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.

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.

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.
