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:
Mano-Mode
EXE resets the peak- and
trough values
OFF turns off the instrument
EXE resets the peak- and
trough values
STEP* leads into the Record-Mode
OFF turns off the instrument

(The numbers shown are home positions.Activa-
ting these numbers will not execute any command.)
*=Mano Record only
= Sensor 1 is active
= HIGH flashes, when maximum pressure
is displayed
= Peak pressure
= Actual pressure
= LOW flashes, when minimum pressure
is displayed
= Trough pressure
4
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!
