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. Precondition: DIP switch 6 is in OFF position.
4. 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 (optional).
Zero point calibration takes place after the countdown period. This is
indicated by continuous LED light and at the display (optional) by
switching from "AUTO 0" to "PROG 0".
Note: By releasing the pushbutton during the countdown
(counter > 0), zero point setting is immediately cancelled!

In the display in the 1
st
line the actual pressure is indicated up to
the measuring range limit.
Switching between the units Pa and hPa (100 Pa = 1 hPa) happens
automatically. Characters displayed:
Pa = pascal
hP = hectopascal

visible (in form of a circle) as well as an indication of the pressure
switchpoint in Pa (adjustable via set potentiometer).

Indication of range exceedance respectively underrunning
When the pressure range is exceeded or underrun, the limit
exceedance is indicated in the 2
nd
display line.
The exceeded pressure range is depicted blinking in Pa, showing
the direction of overrunning.
