GENERAL DESCRIPTION
1
The KELLER Intelligent Manometer is a precise
pressure measuring instrument. Its high accu-
racy, solid construction and its long battery life
make it to an ideal measuring instrument, espe-
cially for measuring tasks where independence
and flexibility are required.
In its standard version, the pressure transducer
is built into the housing as shown below. The
transducer is retained with a counternut.
Mounting:
Screw the male port of the Intelligent Mano-
meter into the female pressure port and tighten
using the lower hexagon of the transducer.
Adjusting the face:
Loosen the upper hexagon of the counternut
and rotate the Intelligent Manometer to the desi-
red position. Retighten.
The face of the Intelligent Manometer can be
rotated through 355°. This feature allows the
Intelligent Manometer to be mounted in all pos-
sible positions; vertical, horizontal or upside
down.
The splash-proof cover of the Intelligent Mano-
meter is sealed with an O-ring and may easily
be removed by hand by turning the display ring
beyond the limit stop (see “Battery Change” in
Chapter “Notes” ” on page 12).

OPERATION
Depressing the front key (marked by a pointed
triangle) sets the Intelligent Manometer into
operation.
After turning on the instrument, all segments of
the display flash three times for operational test.
Between the segment tests, the Intelligent
Manometer displays:
- the measuring range on the upper display
(i.e. 20.00)
- the software program number on the middle
display (MR01)
- the year and calendar week of the program
version (94:23) on the lower right display

KELLER
After this test, the instrument will lead into the
function from which the instrument was pre-
viously turned off.
All commands are selected with the front key.
When the front key is depressed and held, all
commands appear in succession. Releasing
the front key executes the displayed command.
This cycle (constantly depressing the front key
and letting go the key at a desired command) is
subsequently called activation.

MANO-MODE / COMMAND STRUCTURE
3
The Mano-Mode is the standard mode of the
Intelligent Manometer. Since the function of
secondary displays can be selected (see Dise-
Mode), the individual segments are described
with the peak- and trough pressure display:
The arrow with a flashing minus sign re-
presents a “1”, i.e. at 10bar in the over-
pressure range (here 10.034bar).
The two lower displays can also show the tem-
perature or the time since turn on (more infor-
mation see “Dise-Mode” on page 6/7).
The following commands, appearing in the shown
order, can be activated from the Mano-Mode:

EXE resets the peak- and
trough values

ZERO-MODE
The zero of the system can be adjusted with the
command ZERO.
Activate ZERO.
The display shows:
- Upper display: Actual pressure
- Lower left: ZEro
- Lower right: The actual zero
The zero is now ready to be reset. Activate
ZERO once more for permanent zero reset.
After setting the new zero, the Intelligent Mano-
meter returns to the mode it was prior to activa-
ting the ZERO-command.
Note:
If the above setting was activated by mistake,
turn off the instrument with the command OFF.
When restarting, the instrument will lead into
the Mano-Mode.
The Intelligent Manometer may be supplied fit-
ted with two sensors. Within ZERO, one has the
possibility to switch back and forth between the
two sensors with the command EXE. The arrow
on the upper left display points upwards if sen-
sor 1 is active, downwards if sensor 2 is active.
After the selection of the desired sensor, the
zero of the corresponding sensor can now be
reset by activating the command ZERO.

5
MECY-MODE
The measuring cycle can be adjusted between
once per second up to once per hour (59:59).
Longer measuring cycles extend the battery life.
STEP
Activate MECY.
The display indicates CYCL
and the lower right shows
the time in minutes and se-
conds.
The first digit flashes.
EXE increases the digits
(1, 2,…5).
STEP switches to the next
digit.
The second digit flashes.
EXE increases the digits
(1, 2,…9) etc.
Activating RES programmes the new selected
measuring cycle and switches back to the Mano-
Mode.
If the peak- and trough pressure are displayed,
the time period set here has no meaning. When
set in peak/trough mode, the instrument will
always measure in a 1/2-second interval.
MECY (MEsure CYcle)= Adjusting the measuring cycle.

DISE-MODE
6
(MANO RECORD ONLY)
Display Select enables the selection of the dis-
play position, and allocates the measured para-
meter to the chosen display.
There are three selectable display positions:
Upper Display / Lower Left / Lower Right.
These displays can be occupied by the follo-
wing variables:
Symbol Variable
1 Sensor 1
2 Sensor 2 (only if two sensors
are connected)
1-2 Difference (only if two sensors
are connected)
HIGH Peak Value for Sensor 1*
LOW Trough Value for Sensor 1*
25° Temperature
00:00 Time Meter
*If this variable is selected, the
instrument will always measure
in a 1/2-second interval, indepen-
dent from the set measuring cycle.
The selected configuration is valid for both the
Mano-Mode and the Record-Mode.
Please note that not all possible combinations
are programmable.
DISE (DIsplay SElect) = Selection of Display

After activating DISE, the instrument displays
the actual settings. The display that is now flas-
hing can be changed by activating EXE.
If another display possibility is to be adjusted,
activate STEP.
When all possibilities are defined to your needs,
you may return to the new configured Mano-
Mode from any position within DISE by activa-
ting RES.

8
SAVS-MODE
(MANO RECORD ONLY)
The settings programmed in DISE, which are
now active, can be selected for storage under
SAVS. Only the variables which are selected
under SAVS will later actually be stored in the
Record-Mode.
Four different combinations of variables are
offered in the Mano Record. One of the follo-
wing combinations can be selected with the
commmand EXE:
1. Only the variable of the upper display
2. The variable of the upper display and the
lower left display
3. The variable of the upper display and the
lower right display
4. All three variables
Note that the operating hours will never be stored
as an individual variable.
If you have nevertheless selected the operating
hours for storage, they will be neglected during
the storing cycle.
If peak- and trough measurements were selected
for storage, the Record-function will reset the
peak- and trough values after each measure-
ment. Peak- and trough values are monitored
every 1/2 second, the max./min. values occur-
ring during the measurement interval are stored.

SAVS (SAVe Select) = Selection of the values to be stored in the Record-Mode.
Attention:
Each selected variable requires one storage place! If, for example, three variables are to be
measured, the available place will only last for 300 measurements (with three variables) instead
of 900 measurements with one variable!

REC-SEL-MODE
9
(MANO RECORD ONLY)
RECS (REcord SElect) = Preparing the storage
parameters
Activating RECS leads either to Rec-Sel- or to
the Rec-Cont-Mode. The command STEP swit-
ches between these two modes. EXE initiates the
selected function.
In the Rec-Cont-Mode, continuous, endless sto-
rage can be activated (ON) and deactivated
(OFF). Record Continuous=ON means, that the
once started recording can only be interrupted
manually. Record Continuous=OFF means, that
only the specified number of values will be stored.
The Rec-Sel-Mode sets up the number of mea-
surements to be stored and to adjust the recor-
ding interval. The lower left display indicates the
number of measurements, the lower right dis-
play the recording interval in minutes and
seconds.
The value of the flashing digit can be increased
with the command EXE.
STEP switches to the next digit which may be
increased with the command EXE, and so on.
When continuous, endless storage is active
(Rec-Cont=ON), only the measuring cycle can
be adjusted. The lower left display therefore
indicates the message “cont” (for “continuous”)
instead of the numbers of values to be stored.
The command RES leads back to the Mano-
Mode, both from the Rec-Cont-Mode and from
the Rec-Sel-Mode. The new settings are now
made and are active in the Record-Mode.

(MANO RECORD ONLY)
In the Record-Mode, the measured values can
be stored. The measured parameters (see
SAVS-Mode), the number of measurements
and the interval (in minutes and seconds) are
programmable (see Rec-Sel-Mode).
Recording of measuring values:
Activating STEP during the Mano-Mode first
leads into the Prep-Mode (preparation mode)
showing the actual pressure, on the lower left
display the number of the values to be stored
and on the lower right display the measuring
cycle in minutes and seconds.
Activating EXE starts the recording of the mea-
sured values. During the recording, the lower
left display indicates the number of values yet to
be measured, the lower right display shows the
time remaining to the next recording.
The actual measured values are not shown bet-
ween two recordings. They can be displayed by
activating EXE, without interrupting the recor-
ding.
The recording can be ended at any time by acti-
vating RES.
The display END indicates the end of the recor-
ding. Activate EXE to return to the Prep-Mode
or RES to directly access the Mano-Mode.
The starting and ending of the continuous, end-
less recording (see Rec-Sel and Rec-Cont)
takes place the same way. Except that such a
recording can only be ended with the command
RES.

READ-OUT OF THE STORED VALUES
11
DATA TRANSFER TO PC
(only with Logger-Option):
In order to transfer the data from the Intelligent
Manometer into the PC, the special cable K101
and special software is required. The transfer of
data is accomplished over the RS232 serial
interface connected to rear socket of the
Intelligent Manometer.
LOGGER-SOFTWARE
This software serves to transfer the data to a
PC, offering many further processing possibili-
ties of the read-out data.
The LOGGER-Software meets all the require-
ments of modern Windows-Software:
- Graphical Display
- Tabulated Display
- Export into other Windows-Programs
The transfer of the data always starts at the last
recording and can be extended to read out the
entire memory. The memory may be read out as
many times as needed. A detailed manual for
the LOGGER-Software is included when orde-
ring with Logger-Option.
TIME ALLOCATION
After each recording the Intelligent Manometer
writes the status of the Manometer’s time meter
into the memory. When transferring, the abso-
lute time-axis is calculated from the time set in
the PC, the time meter of the Manometer and
the recorded time. The Manometer should the-
refore not be turned off between the recording
and the transfer.
During the recording process, five additional
recording locations for the storage of time are
used for each complete recording cycle.

NOTES
MEMORY
The function REC saves measured values into
the memory of the Intelligent Manometer. New
data is always archived after the last recorded
value, continuously filling the memory. Since
these instruments feature a ring-memory, new
data will only overwrite the oldest data. This
ensures that the maximum amount of most
recent data is always at your disposal when the
memory is full.
TOTAL STORAGE LOCATIONS
Standard: 900
Extended: 8000 (only with memory option)
RESTARTING THE INTELLIGENT MANOMETER
If the Intelligent Manometer program appears to
be locked (the instrument will not respond to
front key operations). This can be rectified by
disconnecting the battery for a period of longer
than 20 seconds. Follow the procedure for
changing the battery. Then restart the instru-
ment.
OVERFLOW/OVERPRESSURE LIMIT
The Intelligent Manometer displays the pressure
until 5 to 10% above the rated pressure range.
If this range is being exceeded, the display indi-
cates “OVFL” (overflow). Do not increase the
applied pressure any more!
If the pressure exceeds the indicated pres-
sure range by more than 20%, the sensor
may be destroyed.
BATTERY CHANGE
Turn the display ring beyond the limit stop. It will
detach from the main housing. Disconnect the
battery connections and remove the old battery.
Insert the new battery with the same pin assign-
ment. Set the display ring back in place.
Settings of DISE, ZERO, RECS, SAVS or
MECY will be lost when the battery is dis-
connected. The Intelligent Manometer will
revert to the original default/factory settings.
This feature can be used to reset the instrument
if necessary.
The Intelligent Manometer will not indicate a
battery low. If the display starts to fade, it’s an in-
dication that the battery charge is weakening.At
this point, we recommend changing the battery.
The batteries can be acquired from KELLER.
After a battery change, it is possible that the
recorded values cannot be interpreted correctly
by the Logger-Software! We therefore recom-
mend that all data is downloaded and safely
stored on a PC before changing the battery.

INSTRUMENTS WITH ANALOG OUTPUT
13
The Intelligent Manometer may be supplied fit-
ted with an optional 0…10V or 4…20mA ana-
log signal output.
The analog signal output must be powered from
an external DC supply. The signal output will
only function when the supply is connected, it is
completely independent of the Intelligent
Manometer’s battery powered measuring cir-
cuits. A battery is still required to power the
instrument.
The connector for the external power supply is
located on the rear side of the Manometer hou-
sing. The corresponding 5-pin plug is included
in delivery.
