OPERATING INSTRUCTIONS
NOTICE: DO NOT TURN GAUGES ON UNDER PRESSURE
INTRODUCTION
The Vaetrix Digital Pressure Indicator is a high accuracy pressure indicator/calibrator. It
has multiple channel sensing capability allowing the operator to monitor the:
(1) Static pressure
(2) Fluid temperature
(3) Ambient temperature
(4) Barometric pressure
The functions are monitored simultaneously and the results are displayed on graphic
LCD. The eGauge1 and eGauge3 are microprocessor-based devices, capable of
displaying 11 different engineering units for pressure and 2 different engineering units
for temperature and barometric. The eGauge1 and the eGauge3 are housed in aluminum
bodies and will be hereafter referred to as eGauge. A MIN/MAX function captures the
extremes of varying pressure signals. The data logging function allows the capability to;
pause, change logging intervals, and switching between “Gauge and Log” mode while in
operation. The log will capture in excess of 100,000 data points and stores the information
under one of 100 different les. The adjustable
damping feature helps eliminate the effects of
pulsation in the system. The eGauge supports a
true auto zero function and is the only gauge to
run a complete system diagnostics to verify the
gauge is in calibration prior to every start up.
It maintains the tightest specications overall
system accuracy in the industry at 0.05% of
Indicated Reading with the combined error
of nonlinearity, hysteresis, and temperature
effects on both span and drift.

OPERATION
The eGauge is initiated by pushing the ON/OFF key.
When the button is pushed there will be a “Snap”
or tactile response, no further force is necessary to
stimulate the gauge to respond. When the gauge is
turned on the screen shown to the right will appear
on the eGauge. The initialize screen will show the
current date and time and current rmware revision.
The second screen will display Full Scale Pressure,
eGauge Serial Number, Last Calibration Date,
and Current Update Rate.
When “MENUS” is displayed, two menus are displayed
as the screen below shows.
The two menu’s available are Pressure Units
Enabled and the Gauge Update Rate. To select
a menu, use the “NEXT” and “PREV” buttons to
navigate to the desired menu. Once the menu has
been selected, press “SEL” to display it. The screen
to the right shows the Pressure Units which are
enabled. To navigate to a unit, use the “NEXT” and
“PREV” buttons. When a unit is selected it will ash.
The “SEL” button will toggle the value either “Y” or
“N”. When all of the desired units have been enabled
or disabled, press the “EXIT” button to return to the
top menu. The default from the factory is all units
are enabled.

OPERATION
The Gauge Update Rate menu allows the user to
change the display update rate to improve battery
life. The menu is shown to the right.
The user can use the “NEXT” and “PREV” buttons
to navigate to an update selection. Pressing the
“SEL” button will select change the update rate to
the current selection. The selections are: 1 every 10
minutes, 1 every 5 minutes, 1 every minute, 1 every
30 seconds, 1 every 15 seconds, and 4 per second.
The gauge must be in 4 per second mode to use
the logging function. Also if one of the lower update
rates is used it is possible to get update in between the timed updates by pressing the
“SAMP” button. When a lower update rate is selected, the status will be show between
RTD 2 and Pressure Units area of the display. The status will show “LP-W” which is Low
Power Waiting or “LP-S” which is Lower Power Sampling.
Pressing the “DONE” button at the menu top level will save the changes to permanent
memory. The eGauge will continue the boot up process.
It will take approximately 30 seconds for it to process through the diagnostics, verication
and zeroing process, during the course of this procedure the display will indicate at what
point in the process the gauge is. The display will briey indicate the full scale pressure
of installed transducer, serial number, date of last calibration, current date and time, and
the barometric pressure reading. During startup the display will show in the status eld
calibrating zero, calibrating RTD, calibrating bar (barometric), and the estimated run time
remaining in the batteries, the hours of operation are based on four batteries installed in
the gauge. The gauge will now be operational indicating the pressure reading, which
should be zero (or if in absolute the barometric pressure), a temperature reading of a RTD
if one is attached.
During the course of startup, if a problem is detected the gauge will terminate and indicate
an error. (See list of error codes). If this occurs, turn the gauge OFF, wait 2 minutes,
verify pressure is not being applied to the static pressure sensor, and turn the gauge
back on, if problem continues, contact the factory for further assistance.
Note: If the gauge is turned off, wait at least 2 minutes before turning it back on. Allow
the gauge a minimum of 45 seconds to go through the self-diagnostics, verication and
auto-zero functions. Turning the gauge ON while pressure is being applied to the Static
sensor will NOT damage the gauge but a ZERO error will occur because the auto-zero
function will perceive a problem and shut gauge down.

KEYPAD FUNCTIONS
In the Gauge Mode the display will indicate the
Static Pressure in the units selected. If the optional
RTD is connected the Test Temperature will be
displayed in the appropriate units.
While in the Gauge Mode, if the UNITS button is
pressed, the display will change the reading from
current units of measure to an alternate pressure
measure unit.
The eGauge is equipped with 6 buttons to
control its operation. The keys are the ON/OFF,
BACKLIGHT, F1, F2, F3, and F4 buttons. The
F1 – F4 keys are soft buttons. Their functions are
dened depending on the operating mode of the
eGauge and are shown on the display above each
key.
ON/OFF Button has one function and purpose,
to turn the eGauge on or off. When the eGauge is
turned on it defaults to eGauge mode. When the
eGauge is turned off it will preserve the last unit of
measurement selected and Log sampling time.
Note: When in log mode, previous les will not be affected but addition points will be
collected. It is recommended to return to gauge mode prior to turning the eGauge off.
BACKLIGHT Button turns on/off the backlight. The backlight will automatically
extinguish after 60 seconds of on time. Pressing the BACKLIGHT button when the
backlight is on will turn the backlight off.
GAUGE MODE

GAUGE MODE
The standard engineering units available are:
(1) PSIG Pounds/inch2Gauge
(2) Kg/cm2Kilograms/centimeter2
(3) MPa MegaPascals
(4) KPa Kilopascals
(5) Bar Bar
(6) IN WC Inches of Water
(7) IN HG Inches of mercury
(8) MM WC Millimeters of Water
(9) FT SW Feet of Sea Water
(10) PSIA Pounds/inch2Absolute
(11) mmHG Millimeters of Mercury
If some of the units have been disabled, then the eGauge will bypass those units.
Note: The conversion factors for inches/millimeter of mercury and water are based on
60oF or 20oC uid temperatures respectively.
When engineering units are changed in the Gauge Mode they will also be changed in the
Log Mode.
Data Acquisition
Data acquisition in the Gauge Mode is accomplished in the following format:
(1) Static pressure measurement and ambient temperature are monitored in real-
time; the display is updated four times per second.
(2) Fluid temperature is acquired through the RTD every 30 seconds and the
display is updated at the time of acquisition.
(3) The barometric pressure is updated every six minutes.
Peak and Valley Pressures
While in the Gauge Mode pressing the MAX button will cause the gauge to display the
maximum or Peak pressure measured since it was turned on. The display will show
this value for approximately 15 seconds. To clear and reset the current value press the
CLEAR Button while it is being displayed, the gauge will automatically record a new
Peak.
Pressing the MIN button in the Gauge Mode will cause the gauge to display the
minimum or Valley pressure measured since it was turned on. The display will show
this value for approximately 15 seconds. To clear the stored value from memory press
the CLEAR Button while it is being displayed, the gauge will automatically record a
new Valley.

LOG MODE
Initiate the Log Mode by pressing the LOG Button.
The gauge will begin the logging setup process.
If the user had programmed through ePlot program
a stage Log Mode, then the user will be given the
opportunity to select the stage mode or regular log
mode. See ePlot documentation for more information
on Log Stage mode.
(Fxxx) is the le number currently selected where
xxx is a number from 1 to 100. It is the rst empty
le in the Log Memory. If the user selects a le which
previously had data in it, the pressure units will revert
to the original value if they are not the same as current pressure units. Also if an RTD was
used, it should also be used in the current log. To change the le number use the INCR
and DECR buttons. The le number can only be changed before logging starts.
(1) Txxx SEC is the time interval between samples. The xxx is the number of
seconds between samples.
(2) START button, will start the logging process.
(3) GAUGE button will stop the logging process and return to the gauge mode of
operation.
If all information is correct at this point, proceed to the next step and press the START
button. The status line will show the estimated time left on the batteries.
(4) The status line of the display will show how
many seconds are left to the next sample.
If the sample time is greater than 10 sec,
the SAMP button is enabled. When this
button is pressed it will capture the current
values of pressure and temperature.
(5) The sample time can be changed by
pressing the INCR or DECR buttons.
The buttons can be held down for auto
increment/decrement.
A Data Point will be taken when one of the following
events occur:
(1) When the log is initiated
(2) At time interval selected
(3) If low battery mode shuts the gauge off

LOG MODE
STATIC PRESSURE
A Data Point consists of:
(1) Date Time Stamp (dd:mm:yy hh:mm:ss)
(2) Test Number or File Identier
(3) Sample Number *
(4) Static Pressure
(5) Barometric Pressure
(6) Test Temperature - If RTD is being used
(7) Ambient Temperature
* The sample number is the nth sample of the current le. When the memory is
erased this number is reset to zero.
To stop the logging process and return to normal operation press the GAUGE button and
the display will show normal gauge valves. When memory storage is full, the display will
indicate MEMORY FULL in the status line and stop logging.
If the gauge is used for more than one test, the Test Number will always show the
rst non-used log. If the log data is to be appended to an existing le, select the le by
pressing the DECR button.
Note: Recommended practice is to download the data stored in memory, verify information
transfer was complete then erase data in gauge before being a new logging operation.
This will ensure enough storage space is available when gauge is logging.
Static pressure measurement is taken from the transducer mounted in the eGauge. (This
very special transducer is the only repairable pressure-sensing device in the market. Ask
your supplier about more details). When the eGauge is rst turned on, the full-scale
pressure range of the device is displayed. The eGauge is designed to be accurate within
the range of 10% to 100% of the full-scale value.
(1) The eGauge is designed to operate with an overpressure limit of 100% of full
scale. Operating above this limit could damage the transducer or affect the
accuracy of the gauge. When operated in access of 100% of full scale, the
operator will see the display numbers start to ash showing unit is passed
100% of full scale.
TEMPERATURE MEASUREMENT
If the eGauge was supplied with the optional Resistive Temperature Device (RTD), the
operator will be able to measure uid or test system temperature. To activate this option,
the RTD must be plugged into the connector on the side of the gauge prior to turning the
gauge on. During the process of verication in the startup phase, the program searches
9

for the RTD. If one is present, it will detect, calibrate and display a temperature reading.
If one is not present, it will not detect it and will continue the process without temperature
indication. The eGauge will operate with or without the RTD attached. The measurement
is in either Standard or Metric and is automatically selected when the Static pressure unit
of measure is changed. In addition to the RTD, the gauge is equipped with an on-board
temperature measure device, which is continuously monitoring ambient temperature. The
only indication of this is during the Log Mode. The temperature is displayed as the log is
started. This temperature is also recorded as part of the log record and will be present in
the le when downloaded. The measurement is in degrees Fahrenheit.
BAROMETRIC PRESSURE
STATUS INDICATORS
The eGauge is equipped with an on-board barometric transducer. The information from
this sensor is displayed in the Gauge Mode and is stored as part of the data record in
the Log Mode. The measurement is in either Standard (inHg) or Metric (mmHg) and is
automatically selected when the Static pressure unit of measure is changed.
Prior to turning the unit on, inspect the vent port to verify nothing is obstructing the
barometric transmitter. If the port is obstructed DO NOT attempt to clear with high
pressure air. Blowing into the barometric vent will cause damage to the transmitter.
When cleaning the eGauge, take special care not to spray water or solvent into the vent
port, any pressure in excess of atmospheric pressure will result in damage to this very
sensitive transducer.
The eGauge has a status eld where Errors or informational data is displayed.
LOW BATTERY INDICATOR
When the battery voltage drops to approximately 2.2 volts, the gauge display will
indicate LOW BATTERY on the status line. The batteries should be replaced as soon as
practical, but the gauge will continue to operate for several more hours, until the battery
voltage drops to below 1.8 volts. At this voltage the gauge will not maintain accuracy,
the system will detect error in the readings and the gauge will automatically switch off.
ERROR CODES
The eGauge has a set of error codes, which will display in the event a parameter violation
is detected. When an error code is displayed, the gauge will not function and may have to
be returned to the factory. The valid error code list is shown in the table below:
Error Code Meaning
“01” Over Pressure
“02” Zero Error
“04” Barometric Error
“05” Calibration Data Error
If an error code is displayed, turn the gauge off, make sure NO pressure is being applied,
wait 2 minutes and then turn the gauge back on. If the problem persists contact the factory.

COMMUNICATION
CHANGING THE BATTERIES
The eGauge is equipped with Blue-tooth device to support communication from the
gauge to a desktop or laptop computer. The Vaetrix PLOT software package provides
access to information stored on the gauge. The program is designed specically for the
eGauge and will not support other forms of communication or other pressure measure
devices. A computer with a Blue-tooth capability is required to communicate with the
eGauge.
The eGauge has a built in routine to verify calibration every time the gauge is turned
on, and a diagnostics to search for abnormal operation, but the accuracy of the eGauge
can be veried by using a certied pressure measurement standard with an accuracy of
+/- 0.0035% of indicated reading.
eGauge3
To replace the batteries, locate the battery cover on the back of the gauge body. At
the center top of the eGauge3, on the cover, there is a self-retaining screw holding
the cover closed and maintaining pressure against the moisture seal. With a at tip
screwdriver, turn the screw counter clockwise to open the battery compartment. The
cover is hinged at the bottom and should swing open freely. Remove the batteries from
the holders.
eGauge1
On replacing the batteries in the eGauge1, use a Phillips head screwdriver. Turn each
screw evenly until lid is loose from body. When replacing, verify that the polarity is in
correct orientation with connector before pushing into holder.
The eGauge has reverse polarity protection, but it will not operate with polarity
reversed. After the batteries are snapped into place, inspect the seals on the lid and
body; any foreign material should be removed prior to closing. (A coating of light
grease or petroleum jelly at the hinge pin locations will prevent problems with
corrosion.) To close and reseal, thread the self-retained screw in the lid clockwise until
resistance can be felt while turning the screw. When the lid and body are parallel the
seal will be activated.
If the batteries need to be replaced while the eGauge is in operation, remove either
the right or left set of batteries. The eGauge will continue to operate on the remaining
two batteries. It is highly recommended that if the eGauge is stored for 90 days or
more without use, that the batteries be removed from the eGauge.

12
When a verification test is required, JM Test Systems recommends two cycles of an
eleven point test procedure be used for the evaluation:
(1) 0% of full scale applied pressure cycle starting point
(2) 20% of full scale applied pressure
(3) 40% of full scale applied pressure
(4) 60% of full scale applied pressure
(5) 80% of full scale applied pressure
(6) 100% of full scale applied pressure
(7) 80% of full scale applied pressure
(8) 60% of full scale applied pressure
(9) 40% of full scale applied pressure
(10) 20% of full scale applied pressure
(11) 0% of full scale applied pressure cycle end point
The following corrections must be made to the dead-weight test system prior
to testing:
(1) The correction factor for local gravity must be determined and applied.
(2) Temperature corrections must be applied to the dead-weight tester if different
from the certied calibration temperature of the device.
(3) Engineering pressure units on the eGauge need to be adjusted to the dead-
weight test units.
(4) Verify the system has NO LEAKS.
(5) Effect of system head is corrected by the AUTO ZERO function of the eGauge.
The evaluation performed will conrm calibration at the test temperature, to verify
temperature effects it is necessary to perform the above test at three temperatures; 0oC,
25oC and 50oC.
If this evaluation indicates performance outside the specications of the eGauge, the
product must be returned to the factory for evaluation, repair and recertication. If
your gauge is malfunctioning, in need of repair, needs calibration or recertification you
must obtain a Return Material Authorization number (RMA) from JM Test Systems.
When returning the gauge, provide an explanation of the problem in as much detail as
possible to facilitate the repair and return. When getting a RMA please provide a PO
number or credit card number at this time.
NOTE: When gauge has been turned off, you will need to wait 2 minutes before
turning gauge back on. Always make sure gauge is turned on in the position that
unit will be used in.
DO NOT TURN GAUGE ON UNDER PRESSURE!!

TROUBLE SHOOTING
The eGauge is a very high performance gauge. Due to the high resolution of this
product, you may observe conditions that appear to be defects in the product, but are
in fact a result of being able to resolve and measure pressure to a degree not possible
with other instruments.
Noisy or Unstable Readings When Used with Fluids
When calibrating or comparing the indicated pressure from an eGauge against a
hydraulic deadweight tester or piston gauge, the reading on the eGauge may appear
unstable–the least signicant digit jumps up and down several counts.
√Reason: Gas (usually air) is trapped in the line between the gauge and the dead
weight tester. What is actually happening is the mass is oscillating up and down, and
the combination of gas and uid is acting like a spring. At higher pressures (above
2000 psi, typically) this may eventually diminish, as the gas dissolves into the uid.
tSolution: Evacuate all tubing with a vacuum pump, before introducing uid into
the system.
Non-repeatability of Pressure Measurements
When checking the gauge against a hydraulic dead-weight, increasing pressure
measurements do not match decreasing pressure measurements.
√Reason: As in the previous note, gas has dissolved into the hydraulic uid. When
decreasing the pressure, the dissolved gas then leaves the uid, but at an uneven
rate, so small pressure differential (due to uid head pressure) may exist between the
reference dead-weight and the gauge being tested.
tSolution: Evacuate all tubing with a vacuum pump, before introducing uid into
the system.
Gauge Display is Blank
√Reason: Battery Dead
tSolution: Install 4 new AA batteries.
After installing batteries Display is still Blank
tSolution: Non Field repairable consult factory.
Batteries Do Not Last
√Reason: Not changing all four batteries at the same time.
tSolution: Change all four batteries at the same time and Switch gauge off when not
in use. continued

18
Display Reading increases with pressure but will not return to zero
√Reason: Debris in probe, probe adapter or hose.
tSolution: Remove connection from end of gauge then use WD 40 and washout
transducer.
Display reading does not increase with pressure increase
√Reason: Debris in probe, probe adapter or hose, reading not above rst .2% of Full
Scale, gauge was turned on under pressure.
tSolution: Clean out probe and adapter or hose, make sure that reading is above rst
.2% of Full Scale and restart gauge making sure not under pressure, if gauge still won’t
read then consult factory.
Readings are not correct
√Reason: Batteries are bad.
tSolution: Replace all 4 AA Batteries.
After Replacing Batteries readings are still not correct
tSolution: Check gauge against standard that is 4 times as accurate as the gauge if
calibration is off will need to consult factor.
