Safety instructions and warnings
Please read these instructions before installing and starting up the
digital manometer.
Failure to follow the instructions will make all guarantee, warranty
and compensation claims null and void.
• Please ensure that the digital manometer is suitable for your
application.
• Please check that the materials that come into contact with the
medium are compatible with the media that are going to be
measured.
• Perfect function and operating reliability of the device can only be
guaranteed for the values specified in the technical data sheet.
• Only qualified persons are permitted to install the equipment and
make the electrical connection, and the correct tools must always
be used.
• Damaged devices must not be started up. If damage occurs
during operation, suitable measures must be taken to
preventpersonsorpropertyfrombeingputatriskbythedamaged

2. Digital manometer description
Thedigitalmanometerisavailableintwoversions PDC-1 and PDC-2
for most varied areasofuse.
The digital manometer offers the user numerous measuring units
(bar, psi and MPa). Additional functions such as MIN/MAX memory,
tare adjustment plus bar graph with trailing pointer function round
off the digital manometer’s profile. The programmable parameters
are adjusted by means of user-friendly keys on the front.

Correct purpose of use
The equipment is only authorised for proper use for its correct pur-
pose. Failure to do this will invalidate all warranties and release the
manufacturer from all responsibility!
The equipment is constructed in compliance with IP65 and should be
protected from excessive amounts of water and dust.
The equipment must be installed so that it is protected from external
damage.
It must be ensured that the manometer is correctly installed and has
the relevant IP protection.
The limits specified in the data sheet must be complied with.
3. Commissioning
Installation
The digital manometer must be connected to the pressure tapping
point in a suitable manner using your own tools. In this case
there must be no occurrence of pressure which exceed the device’s
maximum pressure values. Pressures which exceed the digital
manometer’s maximum range can lead to permanent damage to the
measuring device.
Voltage supply
The digital manometer is operated with 2 Mignon AA batteries.
A flashing battery symbol appears on the display screen if the batte-
rychargeis lowandthebatteriesshouldthen be replacedas soonas
possible. Open the battery compartment lid on the back of the digital
manometer. Replace the batteries with 2 new Mignon cells. Replace
the battery compartment lid.

Min/Max Memory
The min/max memory is updated with the current measured value in
every measuring cycle.
The min. value is displayed by pressing the min. key.
The max. value is displayed by pressing the max. key.
Pressing and holding the appropriate key (min. or max.) and quickly
pressing the menu key at the same time resets the device to the
current measured value.
Bar Graph with Trailing Pointer Function
The integrated bar graph display with trailing pointer function addi-
tionally indicated on the display shows the trend in current working
pressuredirectlyregardlessofthedigitaldisplay.Withthehelpofthe
trailingpointerfunction,themax.storedvalueisalsoindicatedinthe
bar graph display in addition to the digital display in the form of a bar
segment. This bar segment is also updated to the current measure
value when the min./max. value is reset.

Tare Function PDC-2
In this mode the positive deviation of the measured value from the
tared value (max. 20% of the measuring range) is constantly indica-
ted by the main display. The untared pressure value is always shown
on the bar graph display. Thus the digital manometer’s actual wor-
king load can be read off even if the tare function is active. When the
tare function is active, a function indicator appears on the display.
There are 2 possible ways of activating this mode:
1) Select the tare function and set the value to be tared using
the keys . When set, the measured value to be tared is
backed up as tare. The main display and the auxiliary display then
show the value “0000” in the unpressurised state. Example: If a
value to be tared is set as 2 bar, the main display indicates 0 bar
in the unpressurised state.
2) Load the digital manometer with the pressure to be tared.
The current measured value appears in the main display
field of the main display. Select the tare function and then
operate both keys simultaneously . The current measured
value will be backed up as tare. The main display and the auxiliary
display are set to (0000).
Setting the tare value to (0000) resets the tare function in both
models.
