1 Introduction
CAUTION
Do not attempt to set up the HERMIT without first becoming
thoroughly familiar with Appendix B; it contains informa-
tion that is important to avoid damaging your instrument
when it is set up.
Section 1: Introduction
Your HERMIT 2000 Environmental Data Logger is a versatile, self-
contained, and extremely rugged field instrument that enables you
to accurately perform a wide variety of hydrologic and environmen-
tal tests. To mention just a few of the special features of your HER-
MIT 2000, you have the ability to:
• Measure and record parameters such as level, flow, pressure, tem-
perature, conductivity, and pH using standard In-Situ transduc-
ers.
• Easily reprogram your HERMIT 2000 to measure and record pa-
rameters from most industry standard 4-20 mA (milliampere)
current loop transducers.
• Directly monitor and record flow from orifice plate discharge
pipes.
• Collect fast, accurate time-drawdown data from constant-rate or
stepped-rate pump tests, including the recovery phase. This pow-
erful feature is equally suited to slug tests.
• Perform unattended long-term monitoring of aquifers, lakes,
streams, reservoirs, waste-disposal sites, or any environment
where data collection is critical or difficult.
• Record data in as much as 512K bytes (524,288 characters of
information) of non-volatile data storage. Even if the HERMIT
2000’s battery pack should fail, data will remain safe.
• Display and report all measured parameters in their selected
measurement units. Data may be viewed on the large LCD (liq-
uid crystal) display, printed or plotted on an optional field printer,
or transferred to most personal and portable computers via the
built-in RS232C interface.
• Operate the HERMIT 2000 at extreme temperatures without hav-
ing to supply an external power source.
What’s New in Software Version 3.4
If you are already familiar with a previous version of the HERMIT
2000, you may want to take notice of several new features that have
been added to software Version 3.4:
• When you press START to begin a test with Level type inputs, the
HERMIT 2000 will ask whether you have set a reference. See Sec-
tion 7, Running a Test.
• When Level type inputs were used for a test, you can display the
reference level in PSI while viewing the test data. This informa-
tion is also printed in the data file header. See Section 8, Viewing
Stored Data, and Section 10, Printing Data.
How To Use This Manual
This manual has been designed to enable you to gain the maxi-
mum benefit from your HERMIT 2000 and to answer your ques-
tions concerning field installations. If you have just received your
new HERMIT 2000, read Appendix B before you attempt to operate
the instrument. Appendix B contains unpacking instructions and
other important owner’s information.
Then familiarize yourself with the HERMIT 2000 system by reading
and following through the examples in section 2 of this manual —
with your HERMIT 2000. The best way to feel at ease with the instru-
ment is to sit down with the operator’s manual and the HERMIT
2000 and actually key in the examples provided in each of the sec-
tions. It won’t take long to become familiar with your HERMIT 2000
and it is well worth the time invested to obtain a more complete
understanding of the instrument.
Sections 3 through 11 of the operator’s manual discuss each of the
programming and control features of the HERMIT 2000, in the or-
der you will most likely come to use them.
Sections 12 through 14 present field applications of the HERMIT
2000. The procedures presented in these sections will give you a guide
to programming the HERMIT 2000 to solve several common data-
collection problems.
After you’ve become familiar with the HERMIT 2000 system, you
may wish to enhance your data-collection capabilities with additional
inputs, expanded data storage, new types of transducers, and other
field accessories. Be sure to check the accessories list in Appendix A.

2 Getting Started
Section 2: Getting Started
In this section, we will discuss many topics in relatively few pages so
that you can “get on board” fast. For this reason, some of the more
sophisticated concepts are greatly simplified or reserved for later sec-
tions.
After working through this section, you’ll have enough background
to try things on your own, which is an excellent way to attain a good
working knowledge of your instrument. And don’t worry, you can’t
damage the HERMIT 2000 or its accessories with any keyboard
operation.
The Keyboard
How to Wake the HERMIT 2000
The HERMIT 2000 uses a technique referred to as “sleeping” to mini-
mize power consumption, achieving a battery life measured in years
instead of months. Your HERMIT 2000 is naturally narcoleptic, fall-
ing asleep whenever there is no immediate task for the instrument
to perform. When the instrument is asleep, only its internal clock
and keyboard circuits remain active (the data storage memory is
non-volatile and requires no power to retain stored information).
The HERMIT 2000 will wake up when its internal clock indicates
the time for a data point or when you press a key on the front panel.
The sleep mode is recognized by a
blank display.
Lightly press and release any key. The
HERMIT 2000 will wake and respond
with READY in about 2 seconds.
The HERMIT 2000 will remain
awake as long as you are using the keyboard. If you have not pressed
a key for about 60 seconds, the instrument will go back to sleep and
the display will go blank.
READY

3Section 2: Getting Started
Program/Control Keys
Use these keys to select a specific
control or programming feature
of the HERMIT 2000. Most of
these keys do not perform an im-
mediate action but instead
present a menu, or prompt you
for additional information.
If the instrument has dozed off, press
and release any key to wake it up.
As an example, press the DUMP DATA key.
The instrument responds by display-
ing the dump data menu.
Special Function Keys
The special function keys are used
to select options from menus pre-
sented in the display.
Menus will appear on the bottom line of the display in response to a
program or control key selection. F1 selects the first option, F2 the
second, and so forth from left to right.
Continuing with the previous ex-
ample, press F3 to select the AXES
option in the dump data menu.
The axes setup menu is displayed
(menus are often several levels deep).
This menu consists of three selec-
tions, so only keys F1, F2, andF3are
used.
Press F3 to select the Y-AXIS option
from the menu. The instrument now
prompts us for a numeric entry that
will determine from what value the
y-axis will begin.
The Numeric Keypad
The numeric keypad is used to
enter numeric values. You can
also use the keypad to correct en-
try errors and CLEAR out of
menus.
The HERMIT 2000 prompts for a nu-
meric value by displaying a question
mark and an underline cursor.
The default or currently programmed
value for the parameter is enclosed
within brackets. If you wish to use the
displayed value, just press ENTER
without typing any digits.
The instrument will enter the default
value and continue to the next dis-
play. In this example, the next
prompt is for a numeric entry that
will determine to what value the y-axis will extend.
Key in digits and decimal points just
as you would on a calculator.
The –key changes the sign of an
entry value. Press it once to make the
entry negative. . .
. . . again to toggle the entry positive.
Note: Some parameters may require a positive only or an integer
value. In these cases the HERMIT 2000 will ignore the change sign
and decimal point keys to help remind you of the appropriate entry
limits.
Use the CLEAR key to backspace over
an incorrect digit . . .
. . . then continue keying in the num-
ber. Press ENTER to end your entry.
The HERMIT 2000 will enter your
keyed value and continue to the next
display.
The HERMIT 2000 stores numeric values in scientific notation with
eight significant digits. If you enter a number with more than eight
significant digits, the HERMIT 2000 will truncate the entry to eight
digits. The range of values maintained in the instrument is
-.99999999 × 10127 through -.1 × 10127, 0, and .1 × 10127 through
.99999999 × 10127.

Now key in several digits, but don’t
press the ENTER key.
Press the CLEAR key and hold it
down. After about one half second the
key action will begin to repeat.
Continue holding the CLEAR key
until you return to the READY dis-
play. Notice how you travel back-
wards through all the displays you have encountered.
Note: You can use the CLEAR key to back out of any display. If you
end up in a menu or display that you hadn’t intended to be in, just
press CLEAR to back up.
The CLEAR, SCAN, ENTER, and special function keys F1, F2, F3,
and F4 all make use of the auto-repeat feature (all other keys accept
only one press at a time).
Display Control
The HERMIT 2000 features a large, easy-to-read LCD (liquid crys-
tal) display. The display has excellent readability even in direct sun-
light; in fact, the more light the better.
The LCD is optimized for
comfortable viewing from
below the plane perpen-
dicular to the display as
shown.
When viewing the display in low ambient lighting
conditions, it may be convenient to use the electro-
luminescent backlight. Press the BACKLIGHT key
to turn the backlight on; press it again to turn the backlight off.
Try this while shading the display with the operator’s manual. The
backlight will wash out in normal ambient lighting conditions, mak-
ing it difficult to see.
The backlight will switch off automatically when the HERMIT 2000
goes to sleep.
The POWER SAVE Key
Press the POWER SAVE key and release it. The HERMIT 2000 will
blank its display and go to sleep. This action helps to extend battery
life by cutting short the normal 60-second sleep delay.
The READY Display
Press and release any key. The HER-
MIT 2000 will wake and respond with
READY.
The READYprompt is presented whenever the HERMIT 2000 is awake
and ready to accept a program or control key. The READY display
shown above indicates that:
• The instrument is idle. No test is running or programmed to
start.
• The HERMIT 2000 is operating on its internal battery pack
and the battery pack is in good condition.
• The instrument is ready for you to press a program or control
key. All other keys will be ignored.
As the operating status of the HERMIT 2000 changes, other infor-
mation is added to the READY display.
If the internal battery pack begins to
run low, the low bat indicator will be
displayed.
The ext pwr indicator is displayed
when the instrument is operating on
external power.

CAUTION
When the low bat indicator appears in the READY display,
the internal battery pack has no more than one month
capacity remaining, even less depending on instrument
usage. If you are caught with low bat during a test, con-
nect to external power if possible. You cannot lose stored
data even if the battery becomes completely drained. Sim-
ply connect to external power, dump your data, and re-
turn the instrument for a battery replacement.
READY (ext pwr)

The top line of the READY display is
used to display data collection infor-
mation such as Test 0: RUNNING,
indicating that the HERMIT 2000 is recording data for test 0.
The READY display may show a combination of the various indica-
tors; however, the READY still indicates that the HERMIT 2000 is
ready for a program or control key.
Note: The displays shown throughout the operator’s manual are
presented as though the HERMIT 2000 were operating on its inter-
nal battery pack; however, you may wish to use external power dur-
ing your training sessions.
System Self-Test
You can check the operational integrity and
the configuration of the HERMIT 2000 by
pressing the SELF TEST key.
SELF TEST causes the instrument to run through an electronic check
of all internal components, including program memory, data stor-
age memory, and the display. The self-test operation does not affect
the contents of test data stored in memory.
Press and release any key on the key-
board to wake the instrument and get
the READY display.
Press the SELF TEST key. First, the
display is checked by turning on ev-
ery display element.
The instrument then tests its pro-
gram ROMs (read-only memory
containing the instrument’s person-
ality) . . .
. . .then its RAM (random-access
memory used as a scratchpad for
computing results) . . .
. . . and its data storage memory
(used to store the configurations and
results of your tests).
The HERMIT 2000 then reports the
number of watchdog occurrences
and the most recent error code gen-
erated.
The watchdog is an internal electronic circuit that resets the HER-
MIT 2000 when normal operation is upset by nearby lightning strikes,
static discharges, and other similar types of electrical surges. Ideally
the number of recorded watchdogs will remain zero; however, occa-
sional watchdogs associated with storm events can be considered
normal. Unusually high or frequent watchdogs may indicate a mal-
function. Appendix D contains a list of watchdog error codes.
The final self-test display identifies the HERMIT 2000’s configura-
tion and all installed options:
If FAIL is indicated at any point in the self-test sequence, or a high
number of watchdogs are recorded, the instrument may require ser-
vice. See Appendix B for information on how to obtain repair ser-
vice.
Note: If the HERMIT 2000 is recording data, an abbreviated form of
the self-test is performed. After testing the display, the sequence will
skip to the watchdog count. This allows the instrument to respond
quickly to preprogrammed delayed starts and data point time inter-
vals.
The non-volatile data storage used in the HERMIT 2000 has a limit
to the number of times that data can be written to it, referred to as
the memory “endurance.” The self-test configuration display indi-
cates the amount of memory endurance remaining. Your HERMIT
2000 is shipped with 100%. Typically, over 700,000 data points can
be stored before “wearing out” the memory and reaching 0%.
Press the CLEAR key to return to the READY
display.
Using Your HERMIT 2000
Let’s try a simple data collection problem to get the feel of your HER-
MIT 2000. For the examples illustrated here, it will not be necessary
to connect a transducer to the instrument. If the HERMIT 2000 hap-
pens to fall asleep while you are working through the problem, you
will have to wake it up and repeat the section you were on from the
beginning. If you make an entry error while keying in the example,
just use the CLEAR key to back up.
For our example, we will record pressure for a few minutes using a
standard In-Situ pressure transducer.

Defining the Test
The process of collecting a set of data with the HERMIT 2000 is re-
ferred to as “running a test.” The first step in running a test is to
define the basic test conditions.
• What test number we will be performing.
• At what rate to sample the input channels.
• How many input channels we will be using.
• What type of data will be collected on each input channel.
The HERMIT 2000 allows you to record as many as twenty different
tests in memory, each with its own unique setup and data, without
having to dump the data between tests. Tests are always recorded
sequentially from test 0 to test 19. Let’s clear the memory of any old
tests and begin with test 0.
Press and release any key on the key-
board to wake the instrument.
Press the SETUP TEST key to begin pro-
gramming.
The HERMIT 2000 responds by ask-
ing you what test number you wish
to set up.
The test number shown in the display is the next safe test num-
ber—the next available test number that can be run while still re-
taining data recorded in lower numbered tests. The default number
is also the highest test number you can select since tests are recorded
consecutively. You may select any test number from 0 to the default
selection shown.
Key in test 0 and press ENTER.
The HERMIT 2000 will tell you if
your selected test number will cause
previously recorded tests to be erased.
Press F4 to confirm that the recorded tests are no longer needed and
may be erased.
Note: If you do not wish to have data erased, press CLEAR and use
the default test number.
After pressing F4 you are given one
last chance to change your mind!
Key in the erase code as shown in the
display and press ENTER . The in-
strument will not erase data until the
correct code is entered.
The indicated tests are then erased
and the data storage is set up for our
new test.
The display will show the number of
data points that can be collected with
the current setup, along with the
number of days that we can run at the present rate . . .
Note: The numbers that appear in your display may be different
from those shown here depending on the amount of storage and the
number of input channels installed in your instrument, as well as
the previously programmed setup for test 0.
. . . followed by the test setup menu.
The alarm start option will be explained in detail in later sections.
For the time being, let’s make sure that it is turned off:
Press F1 to select the ALARM option
in the test setup menu.
We are presented with a new menu
selection. The current setting of the
alarm start option is shown enclosed
within brackets. Press F2 to make
sure it is OFF.
Programming the Sample Rate
Press F2to select the RATE option in
the test setup menu.
The instrument prompts us to select
the sample mode. The current selec-
tion is shown in brackets. Press F3
to select LIN1 (linear mode 1, data
points spaced evenly over time).
Next we are prompted to enter the
sample rate in minutes. Since we
want to see things happen fast, let’s
take a data point every minute.
Key in 1 and press ENTER .
Our new data capacities are displayed
. . .
. . . and we are returned to the test
setup menu.

Selecting the Number of Transducers
Next, we need to program the number of input channels and trans-
ducers (abbreviated XD in the displays and on the keyboard) that
will be recorded during the test.
Press F3to select the #XDs (number
of transducers) option in the test
setup menu.
The instrument prompts for the
number of transducers. The current
selection and default value is dis-
played within brackets.
For our example we will be using one
transducer. Key in 1 and press EN-
TER .
Our new data capacities are displayed
. . .
…and we are returned to the test
setup menu.
Defining Input Data Types
The last step in defining our test is to select the type of data to be
collected on each input channel. Selection of the data type will de-
termine both the measurement technique used to sample the trans-
ducer connected to an input and the equations used to convert the
measurement results to appropriate units.
Press F4to select the TYPE option in
the test setup menu.
We are presented with a menu of 4
data types. The type of data is inde-
pendently programmable for each
input channel. The current selection
is shown next to the input channel number.
Press F3 to select the FUNC (func-
tion) option from the menu. The dis-
play will confirm your selection.
The function data type allows you to collect data from any 4-20 mA
transducer and convert the results to the desired units using a simple
linear or quadratic equation. The other data types provide more com-
plex data reduction features and will be discussed in later sections.
Press CLEAR to exit the data type
menu. Our new data capacities are
displayed . . .
. . . and we are returned to the test
setup menu.
Press CLEAR again to exit the test
setup menu and return to the READY
display.
From this point on, all other functions and menu displays will be
automatically tailored to match your SETUP TEST selections. For
this reason it is important to configure the test using the SETUP
TEST function before attempting to alter other programmable set-
tings.
Setting Up the Inputs
Now that we have set up the basic test parameters, we need to pro-
gram the values that will determine how the 4-20 mA outputs of the
transducers will be converted to meaningful units.
If the HERMIT 2000 has dozed off,
press and release any key to wake it
up again.
Press the XD key to gain access to the trans-
ducer menus.
The transducer menu for input chan-
nel 1 is displayed along with a re-
minder that the input has been pro-
grammed as a function type.
Press F4 to select the more option
from the menu. Additional menu
options for our function type input
are displayed.
The linearity (LIN), scale factor (SCALE), and offset (OFFS) pa-
rameters shown in the menu will program the coefficients of a qua-
dratic equation that will convert the transducer output to the desired
units. The values for these “Quadratic Coefficients” are generally
found on a data tag attached to the cable reel.
For purposes of this ex-
ample, our pressure trans-
ducer has a scale factor of
50.078 and an offset of
0.036. These values will
convert readings to PSI
units.

Key in a warmup delay of 1000 mSEC
(milliseconds) and press ENTER.
The HERMIT 2000 will power the
transducer for one second before tak-
ing a reading.
Note: The warmup delay is rarely specified on third-party transduc-
ers and must often be determined by experiment. In-Situ’s standard
transducers use a warmup delay of 50 mSEC unless specified other-
wise. A one-second delay is used here only for the purpose of ex-
ample.
Press CLEAR to exit the parameter
menu . . .
. . . and return to the first input setup
menu. Press F1 to select the READ
option.
The HERMIT 2000 will power the
input channel and wait for the pro-
grammed warmup delay period . . .
. . . and then take a transducer read-
ing and turn off the input channel.
We are warned that no transducer
has been connected to the input
channel.
If a transducer had been connected, the HERMIT 2000 would have
displayed the reading in the programmed units. Press ENTER to
take additional readings from the same transducer. These readings
will confirm that the transducers are properly connected and that
you have programmed the transducer parameters correctly. For this
example, we will leave the transducer disconnected.
Press CLEAR to return to the trans-
ducer menu.
Press CLEAR again to return to the
READY display. We’re now ready to
start collecting some data.
Starting the Test
From the READY display, press the START/
STEP key.
The instrument displays the start
menu. Press F1 to select an IMME-
DIATE start.
The data point display flashes briefly
to indicate that a data point has been
recorded at an elapsed time of 0 min-
utes.
We are then returned to the READY
display. Notice that a test RUNNING
indicator has been added.
The HERMIT 2000 will record a transducer reading once every
minute until you STOP the test or all the available data storage space
is used up.
As you continue with the example,
you will be interrupted occasionally
as the instrument takes another data
point.
Viewing Recorded Data
From the READY display, press the VIEW DATA
key. Recorded data can be viewed while the test
is running or after the test is stopped.
You are prompted to enter a test
number for viewing (you can also
view tests other than the one that is
running). The default selection is the currently running test or the
highest test that has been run. Press ENTER to select our sample
test.
Next select the test step. Press ENTER
to select step 0.

Note: Tests can be subdivided into steps by re-starting the test in
coincidence with a particular test event, such as the change in pump-
ing rate during a stepped-rate pump test. When you first start a test
you are automatically in step 0. Detailed discussions of step testing
are reserved for later sections.
Next select the percentage into the
test data you wish to begin viewing.
Zero percent is at the beginning of
the test; 100 percent is at the end of the test, or the most recent data
point if the test is still running.
Let’s view data from the beginning
of the test by keying in 0 and press-
ing ENTER .
The display shows our recorded data
in PSI at an elapsed time of zero
minutes (the start of the test). Our
pressure readings show negative re-
sults since we did not connect a transducer to the input channel.
Use the SCAN keys to scan through the recorded
data. SCAN UP scans in the direction of in-
creasing elapsed time; SCAN DOWN scans in
the direction of decreasing elapsed time. These
keys will auto-repeat if you continue to hold
them down.
If you press SCAN DOWN while view-
ing data at elapsed time zero . . .
. . . the display will show the start date
and time momentarily (which may
be incorrect since we did not set the
clock before starting the test) . . .
. . . then return to the view data dis-
play.
Note: The arrows in the display indicate that function keys F1 and
F2 may be used to scan through the input channels. Since we have
programmed only one input channel, these keys perform no function.
Press CLEAR to back out of the view
data display. Note that the view per-
centage shows the point at which you
stopped viewing. If you wish, you can move quickly to another point
in the test by entering a new percentage.
Press CLEAR again to exit to the

WARNING
Always begin the setup of a new test by first selecting a test num-
ber with the SETUP TEST function. If you begin with any other
function you may be inadvertently editing the parameters of
your previous test. Your test data is completely secure and
uneditable only after incrementing to the next test number.
Stopping the Test
To stop data recording, press the STOP key.
You are asked to confirm the stop
command by pressing the ENTER
key.
Note: If the STOP key was pressed accidentally or you do not wish to
stop the test, press CLEARto back out.
Press ENTER to stop the test. The
HERMIT 2000 will take a few seconds
to organize the data storage . . .
. . . then will return you to the READY
display.
Data Security
Once you have stopped a test, the raw transducer data recorded in
memory cannot be altered; however, you may edit the transducer
parameters in the XD menus. Since raw data (transducer data be-
fore computing the units) is stored separately from the transducer
parameters, you may correct errors in the parameters without hav-
ing to recalculate your data.
If you set up for a new test by selecting the next test number as
presented by the SETUP TEST function, all previous data and setup
parameters become protected and cannot be altered. Any changes
you make in programming will pertain only to your current test.
Review
As you may have begun to realize, the HERMIT 2000 is capable of
running much more sophisticated tests than the one demonstrated
in this section. We will jump right into the detailed operating and
programming features beginning with the next section. If you are
not yet comfortable with the basic operation of the instrument, you
may wish to review the material presented in this section before con-
tinuing.

10 Section 3: Time of Day Clock
3 Time of Day Clock
The HERMIT 2000 maintains an internal, battery powered, time of
day clock. The clock remains operational when the instrument sleeps,
keeping track of the month, day of the month, and the time of day in
hours, minutes, and seconds. The clock is used to record the start
date and time of a test, and may be used to program delayed start
operations.
Time is kept in the 24-hour, or military, format, where 0 hours is
midnight. A time of 11:00 indicates 11 A.M. and a time of 23:00
indicates 11 P.M. The clock runs on a four-year cycle and does not
keep track of leap years.
Displaying the Clock
Begin at the READY display. The
clock can be displayed while in any
operating mode.
Press the CLOCK key.
The HERMIT 2000 will display the
current date and time.
Press CLEAR to exit to the READY
display. If no key is pressed, after 10
seconds the display will return to
READY automatically.
Setting the Clock
The time of day clock can only be set while the HERMIT 2000 is idle.
The clock cannot be set if the instrument is running a test or if it is
waiting for a delayed or alarm start.
Press the CLOCK key while at the READY display.
The HERMIT 2000 will display the
current date and time. Press ENTER
to begin setting the clock.
Note: If the instrument is not idle, the ENTER prompt will not be
displayed and the ENTER key will be ignored.
The HERMIT 2000 first prompts for
the month. The month must be in
the range 1 to 12. Don’t forget that if
the value shown within the brackets
is correct, you can press ENTER without re-keying the value.
The day of the month must be in the
range 1 to 31 and is checked against
the maximum number of days in the
month just entered.
The hour must be in the range 0 to
23.
Enter minutes in the range 0 to 59.
Seconds must also be in the range 0
to 59. The clock is set as soon as you
press ENTER .
The new date and time are displayed.
If you have set any parameter incor-
rectly, press ENTER and repeat your
entries.
Press CLEAR to exit to the READY

11Section 4: Setting Up a Test
4 Setting Up a Test
In Section 2, the SETUP TEST function was used to program the
four basic parameters of a test:
• Selection of the test number
• The sample rate
• The number of input channels to use
• The type of data to be collected on each input channel
Since other functions and menu displays will be tailored to your
SETUP TEST selections, it is important to properly set up a test be-
fore programming other instrument functions. This section will ex-
pand on the options available in the SETUP TEST menus.
Selecting the Test Number
Begin at the READY display. If the
instrument is asleep, press and re-
lease any key to wake it.
Press the SETUP TEST key to begin program-
ming.
You cannot set up a new test if a test
is running or if the HERMIT 2000 is
waiting for a delayed or alarm start.
A new test can be programmed only
when the instrument is idle. The
HERMIT 2000 responds by asking
you to select a test number.
You can record as many as twenty tests, numbered consecutively
from 0 to 19, each with its unique setup and data. The default test
number shown in brackets on the display is the next available test
number; selecting it will ensure that test data already recorded in
the instrument will not be overwritten. Test numbers cannot be se-
lected out of sequence. The test number shown in the display is the
highest entry you can make.
Press ENTER to select the default test
number. The previous test setup is
copied to the new test . . .
. . . the available data point capacity
and test time in days is displayed . . .
. . . followed by the test setup menu.
Note: The setup parameters are copied from the previous test to sim-
plify re-running a test (you don’t have to re-enter all of the test pa-
rameters). Of course, the test setup can be modified or completely
changed if you wish.
Erasing Old Tests
As you continue to record tests into the memory, you will find that
the amount of memory available for new tests continues to grow
smaller. This translates into fewer days of recording at a given sample
rate, or longer sample rates to achieve the required test lengths. At
some point it will become desirable to erase old test data to free up
the memory for a new test. You can erase old test data by selecting a
lower test number than the default test presented by the HERMIT 2000.
Begin at the READY display.
Press the SETUP TEST key to begin program-
ming.
When you are prompted for a test
number, key in the lowest test num-
ber you wish to erase.
The test number you select, and all higher test numbers, will be
erased. Selecting test 0 will cause all test data to be erased.
The HERMIT 2000 will warn you
when your selection will cause previ-
ously recorded tests to be erased. Press
F4 to confirm the selection.
Note: If you do not wish to have data erased, press CLEAR and use
the default test number.

ment will not erase data until the
correct code is entered.
The indicated tests are then erased
…
. . . the amount of storage now avail-
able is displayed . . .
. . . followed by the test setup menu.
The setup parameters for the selected test are not erased. You may
re-run the test using its old parameters, or modify them as needed
for a new test.
Sample Rate Options
The sample rate determines how often input channel readings will
be recorded. All input channels share the common sample rate set-
ting. There are two parts to the sample rate setting. The sample mode
is set first; the four choices are described on the following pages. The
sample rate (interval between readings) is prompted next.
Press F2 in the test setup menu to
select the RATE option.
You are first prompted to select a
sample mode. The currently pro-
grammed mode is shown in brack-
ets. Use the special function keys F1-
F4 to select one of the four available sample modes:
LOG logarithmic sampling schedule (see below)
USER customized sampling schedule (see p. 13)
LIN1 data points spaced evenly over time (minutes)
LIN2 data points spaced evenly over time (seconds)
You are then prompted for the
sample rate (interval between read-
ings). This prompt will vary depend-
ing on the sample mode. The currently programmed rate is shown
in brackets. Key in the sample rate and press ENTER.
Allowable entries are:
LOG 0-1440 minutes (see below)
USER 1-65535 minutes, 1-65535 points (see p. 13)
LIN1 1-1440 minutes
LIN2 2-59 seconds
The amount of storage and the num-
ber of days that can be run at the se-
lected rate are displayed . . .
. . . and you are returned to the test
setup menu.
Linear Sampling (LIN1 & LIN2)
Selection of a linear sampling mode causes the HERMIT 2000 to
record one reading from each active input channel at the specified
sample rate.
In Linear mode 1 the sample interval can be set from 1 minute to
1440 minutes (one day). This mode is useful for collecting long-
term data and for recording background data prior to running pump
or slug tests.
Linear mode 2 allows faster sampling: 2 to 59 seconds between read-
ings. Use this mode for collecting fast, continuous data for short tests.
The following points should be considered when setting up a test in
the Linear 2 sample mode with a very fast sample rate:
•Transducer Delays: The sample rate must be equal to or longer
than the sum of the transducer delays. These include the warmup
delay, prompted in the transducer menus (Section 5) and the
time required to read each dual-mode probe (5 seconds), plus
one second for the HERMIT 2000 to perform internal calcula-
tions. You will not be allowed to exit the Test Setup menu if the
sum of the delays exceeds the sample rate.
•Keyboard Operation During the Test: Because of the rapidity
of data collection in the LIN2 mode, the HERMIT 2000 can’t do
anything else while the test is running. Only the STOP function
is active (see Section 7).
Logarithmic Sampling
Log sampling optimizes data collection speed and memory usage
for pump and slug tests. Pump and slug tests characteristically be-
ginwith very rapid changes in values, and end with very slowly chang-
ing values. If you were to program a very fast linear rate, you could
characterize the early stages of the test; however, you would be quickly
inundated with excessive data during the later stages of the test, pos-
sibly running out of memory before the test is complete. Conversely,
a slower linear rate would allow you to run a test longer, but would
not provide enough early-time information to properly characterize
the data.

13Section 4: Setting Up a Test
The log sampling mode of the HERMIT 2000 solves these problems
by using the sampling schedule outlined below.
Standard Log Schedule
Log Cycle Elapsed Time Sample Interval Points/Cycle
1 0-20 seconds 0.5 second 41
2 20-60 seconds 1 second 40
3 1-10 minutes 12 seconds 45
4 10-100 minutes 2 minutes 45
5 100-1000 minutes 20 minutes 45
6 1000-10,000 minutes 200 minutes 45
7 > 10,000 minutes 1440 minutes
As you can see, the sample intervals begin closely spaced and are
automatically made longer with each log cycle. To use the standard
log schedule, enter 0 or 1440 at the sample rate prompt.
You can tailor the standard log schedule to suit your requirements
with an appropriate choice of sample rate. In the log mode, the
sample rate you enter determines the maximum sample inter-
val you wish to have occur during the test. The HERMIT 2000 will
collect data according to the standard log schedule until it reaches a
log cycle with a sample interval greater than your programmed
sample rate. Sampling then switches over to the programmed sample
rate for the remainder of the test.
For example, if you select the log sampling mode and key in a sample
rate of 5 minutes, the instrument would record data using the fol-
lowing modified log schedule.
Log Cycle Elapsed Time Sample Interval
1 0-20 seconds 0.5 second
2 20-60 seconds 1 second
3 1-10 minutes 12 seconds
4 10-100 minutes 2 minutes
5 100 minutes . . . 5 minutes
Since the fastest sample rate you can enter is one minute, the instru-
ment will always use the standard schedule through log cycle 3.
Consider the following when setting up a test in the log sample mode:
•Transducer Warmup Delay: During the first ten minutes (log
cycles 1 through 3), the HERMIT 2000 uses a transducer warmup
delay of 50 mSEC for all active inputs, regardless of the warmup
delays programmed. After cycle 3, the programmed warmup de-
lays are used. Make sure that the transducers you choose are com-
patible with the fast data requirements of the log sample mode.
•Dual-Mode Transducers: Due to the time required to read a
dual-mode transducer, all dual-mode data recorded during the
first three log cycles (ten minutes) will be meaningless and should
be ignored. The data recorded during this period will vary de-
pending on the coefficient settings, but the start of good data
should be readily apparent.
User-Defined Sampling
The “USER” sample mode allows you to design a custom sampling
program for your test. The program consists of eight distinct sam-
pling cycles which you define. For each cycle, you specify the sam-
pling rate (interval between readings) and the number of data points
(readings) to be collected. The instrument determines the length of
each cycle based on your entries.
In cycles 1 through 7, samples can be taken at intervals of 0.5 sec-
ond, 1 second, 2-59 seconds, or 1-65535 minutes. In cycle 8, samples
can be taken at 2-59 seconds or 1-65535 minutes.
When you select the USER sample
mode, you are first asked whether to
use a NEW or an OLD user-defined
schedule. Press F1 to define a new schedule; press F2 if you have
previously defined a schedule and wish to use it again, or to select
the default user schedule (see next page).
If you select OLD, no further information will be requested. You will
be returned to the test setup menu.
If you choose NEW, you will be asked
to specify the rate (interval between
readings) for the first cycle. The cur-
rent rate for cycle #1 is shown in brackets. Use the special function
keys F1-F4 to select one of the four available options.
If you choose 0.5 second (F1) or 1.0 second (F2), the selected rate
will be entered and the prompt for Points will come up.
If you choose seconds or minutes,
then use the numeric keypad to en-
ter the rate. The allowable range for
Seconds is 2-59. The allowable range for Minutes is 1-65535. Press
ENTER when you have specified the rate.
Then specify the number of data
points to be collected in cycle #1. The
current number of points is shown
in brackets. Key in a number and
press ENTER. Minimum: 1. Maximum: 65535. Maximum for a cycle
with 0.5-sec or 1-sec sample rate: 255.
Now cycle #1 is defined. The rate times the number of points deter-
mines the length of the cycle. For the example above, a 5-minute
sampling rate for 12 points equals an hour (5 ´12 = 60).
Note: For cycle #1, an initial data point will always be taken at time
= 0. For the example above, the data logger will record 12 points
plus one point at time = 0 for a total of 13 actual points recorded
during cycle #1.
User defined test:

#1 rate (sec) [0.5]?
0.5s 1.0s sec min
#1 rate (min) [2]?
5_
#1 points [10]?
12_

14
When you have set the sample rate and number of points for cycle
#1, you will be prompted for the same information for cycles #2
through #7.
For cycle #8, there are only two rate
options. Press F3 to select seconds,
then key in a number between 2 and
59, or press F4 for minutes, and key
in a number between 1 and 65535.
In cycle #8, you will be prompted only for “rate.” The HERMIT will
automatically calculate the number of points that can be taken at
that rate based on the instrument’s available memory.
You need to define all eight cycles. If your test only requires four
distinct cycles, you can, for example, define cycles 5 through 8 to be
exactly the same as 4. Or make 1 and 2 identical, 3 and 4 identical, etc.
The default user-defined schedule is shown below.
Standard [Default “OLD”] User Schedule
Here are some suggestions to help you set up a USER schedule:
• The schedule shown above remains in the instrument’s memory
as the current “OLD” schedule only until you change any of the
values. Then your changes become the “OLD” schedule.
• To see the settings for the current “OLD” schedule, select NEW;
the most recent settings will be shown in brackets as the defaults.
• You don’t need to make the sampling less and less frequent, as in
the schedule above. You could specify the early cycles to be sparse,
for example, then put in every-minute sampling for one cycle,
then go back to sparse.
• You can use part of the OLD schedule by pressing CLEAR after
you have defined a couple of NEW cycles. If you press CLEAR at
any point while defining a USER schedule, the HERMIT will use
the last-defined schedule for the remaining cycles.
• One day is 1440 minutes.
The Number of Transducers
From the test setup menu, press F3
to program the number of transduc-
ers (#XDs).
You are prompted to enter the num-
ber of transducers to be used during
the test. The current selection is
shown in brackets.
When you press ENTER, the amount
of storage and the maximum test
length are displayed . . .
. . . and you are returned to the test
setup menu.
Input channels are always used sequentially. If you program two
transducers for a test, they should be connected to input channels
one and two, four transducers should be connected to input chan-
nels one through four, and so on.
More About Input Data Types
To review or change input types, press
F4 to select the TYPE option in the
test setup menu.
The display will show the type selec-
tion for input channel 1 and a menu
with four type options.
Use the SCAN keys to review the type
selection for each input. The menu
selections remain the same for all
inputs.
The SCAN keys will auto-repeat when held down longer than about
a half-second.
Use the special function keys to
change the type of the displayed in-
put channel.
When you have set the data type for
all your active input channels, press
CLEAR to exit. The display will show
the amount of free storage . . .

Battery Life Tip
Do not program the number of transducers to a number
greater than the number that will actually be used. Re-
cording data from unused input channels wastes battery
power and data storage space.

. . . and then return to the test setup
menu.
The selection of a data type defines two important characteristics of
an input channel.
• The technique used to power up, and take a reading from,
the transducer connected to the input channel.
• The data reduction equations that will be used to convert the
raw output of the transducer to meaningful results in the
desired units.
In this section we will present a brief description of each of the input
types and their basic uses. The parameters used with each input type
are programmed via the XD function key and are discussed in detail
in Section 5.
Function Type
Press F3 to program an input chan-
nel as a function (FUNC) type.
The function type input uses a flexible quadratic equation to con-
vert the output of any conventional 4-20 mA transducer to its basic
measurement units. Use the function type to obtain direct readings
of pressure from a pressure transducer, temperature from a tem-
perature transducer, flow from a flow transducer, etc. With proper
modification of the quadratic equation coefficients, transducer read-
ings can be reported in any equivalent units of measurements (tem-
perature in degrees Fahrenheit or degrees Celsius, for example).
Level Type
Press F1 to designate an input chan-
nel as a level type.
The level type input allows you to use pressure transducers to solve a
wide variety of water level measurement problems. It first uses the
basic quadratic equation to convert the 4-20 mA output of a pres-
sure transducer to units of PSI (pounds per square inch). PSI units
are then automatically converted to water levels in selectable units
of feet or meters. You can even select surface water or top of casing
orientation and program the specific gravity of the water or fluid
you’re working in.
Flow Type
Press F2 to designate an input chan-
nel as a flow type.
The flow type input gives you the ability to use a pressure transducer
to indirectly measure the flow rate from a discharge pipe equipped
with an orifice plate. In a manner similar to the level type input, the
4-20 mA output of a pressure transducer is converted to PSI. PSI is
then converted to flow using a standard orifice equation and a
programmable calibration coefficient.
Dual Type
Press F4 to designate an input chan-
nel as a dual type.
The dual type selection is used with dual-parameter transducers such
as In-Situ’s conductivity/temperature and pH/temperature transduc-
ers. This type of transducer permits the recording of two parameters
with a single input channel.
Exiting the Test Setup Menu
The HERMIT 2000 checks for illegal test parameters before you can
exit the test setup menu.
If the sum of all the transducer de-
lays exceeds the programmed sample
rate, select a longer sample rate.
In figuring the delays, include:
(1) the warmup delay for each function, level, and flow type trans-
ducer programmed; these are prompted in the transducer
menus (Section 5) and will normally be 50 mSEC, plus
(2) 5 seconds required to read each dual type programmed, plus
(3) 5 seconds for instrument wake-up (log mode and LIN1 only
— the HERMIT 2000 doesn’t go to sleep in LIN2 mode), plus
(4) 1 second for internal calculations.
For example,
10 XD’s with 50 mSEC delays = .5 second
2 dual probes = 10 seconds
Internal calculation = 1 second
Total delays = 11.5 seconds.
You would not be allowed to start this test with a sample rate less
than 12 seconds in the LIN2 sample mode.
Note: If you change transducers and then try to set up a new test
with a fast LIN2 sample rate (say, 2 seconds), it is possible that the
test setup copied from the previous test will include transducer de-
lays that exceed the new fast sample rate. In this case, you will have
to “trick” the HERMIT 2000 into letting you exit the test setup menu:
First, program a sample rate long enough to accommodate the pre-
vious delays. Then access the transducer menus and input the new
delays. Then re-access the test setup menu and set the 2 second LIN2
sample rate.

16 Section 5: Setting Up Transducers
After setting up the basic test parameters using the SETUP TEST
function, you need to identify the transducers that will be connected
to each input channel. Once identified, the HERMIT 2000 will have
enough information to convert the output of each transducer to the
appropriate measurement units.
To access the transducer menus, press the XD
(transducer) key when you are at the READY
display.
Transducer parameters for the current test number can be pro-
grammed or modified while in any test mode (idle, running, etc.).
The display will show the transducer
menu for input channel 1.
Use the SCAN keys to move to the
desired input channel. The menu
selections vary automatically to
match the data type of the input
channel.
Assigning an I.D.
Each input channel can be assigned an eight-character identifica-
tion to help document field test conditions. You can program the
I.D. with a well number, transducer serial number, or any other piece
of meaningful information. The I.D. is optional and may be left
blank.
Press F2 in any transducer main
menu to select the I.D. option.
You will be prompted to enter the I.D.
The current setting of the I.D. is
shown within brackets.
You can key in digits directly using
the numeric keypad . . .
. . . or use the SCAN keys to change a
keyed digit to any character or sym-
bol.
You can key in up to 8 digits, sym-
bols, or characters. Longer entries
will be truncated to the first 8 char-
acters. Entries less than 8 characters
will be left-justified and padded with spaces.
When you press ENTER, the display
will return to the transducer menu.
The I.D. will replace the type descrip-
tion in the top line of the display.
Clearing an I.D.
The input channel I.D. will be output with printouts, plots, and data
transfers, and will be copied along with other transducer param-
eters from test to test. Keying in a new I.D. will overwrite an old I.D.
in the same manner as keying in a new numeric value will replace
an old value. Use the following procedure to completely clear an
unwanted I.D.
Press F2 to select the I.D. option.
When you are prompted for a new
I.D., key in any digit . . .
. . and SCAN DOWN until you reach
the space character. Press the ENTER
key.
5 Setting Up Transducers
IMPORTANT
Do not begin setting up transducer parameters until you
have selected a test number and programmed the basic test
parameters using the SETUP TEST function. Otherwise you
will be editing transducer parameters from the previous test.
