1. For zero point setting, the device must be in operation for
at least 60 minutes.
2. Connect pressure inputs P (+) and P (–) with a hose.
(Pressure difference between the inputs = 0 Pa).
3. For zero point setting, press pushbutton uninterrupted for 10 seconds.
By pressing the pushbutton, a countdown of ca. 10 seconds is started.
The yellow LED is blinking and the countdown is shown on the display.
Zero point calibration takes place after the countdown period.
This is indicated by continuous LED light and at the display by switching from
"AUTO 0" to "PROG 0".
Note: By releasing the pushbutton during the countdown
(counter > 0), zero point setting is immediately cancelled!

The 1 st line in the display shows the actual pressure .
The 2 nd line shows the unit pascal (Pa).
The 3rd line shows the information regarding the
switching status of the relay (as a circuit) on the left side,
as well as the respective switching value Pa on the right side.
The switchpoint can be adjusted via the "SET" potentiometer.
This depends on the adjusted measuring range.
Please note that the switchpoint is displayed without a comma
for the 25 Pa variant (e.g. 100 = 10.0 Pa)
Display readout:
Manual offset adjustment:
Automatic zero point calibration (optional):
The offset potentiometer functions additionally and
independently for automatically setting the zero point.
With the OFFSET potentiometer, a deviation outside of the zero
point can be aligned.
The range for adjustment is ca. ± 10 % of the pressure range.
A zero point calibration is carried out cyclically via an internal
valve.
Cycle time (approx. 90 minutes) is fixed in the factory.
During the automatic calibration, the output value remains at
its last pressure value.
