8.3 Pos. zero adjust
The pressure resulting from the orientation of the device can be corrected here.
Parameter name Description
Corrected press. (172)
Display
Menu path:
Setup Corrected press.
Displays the measured pressure after sensor trim and position adjustment.
If this value is not equal to "0", it can be corrected to "0" by the position adjustment.
Pos. zero adjust (007)
(Deltabar M and gauge
pressure sensor)
Selection
Menu path:
Setup Pos. zero adjust
Position adjustment – the pressure difference between zero (set point) and the
measured pressure need not be known.
Example:
– Measured value = 2.2 mbar (0.032 psi)
– You correct the measured value via the "Pos. zero adjust" parameter with the
"Confirm" option. This means that you are assigning the value 0.0 to the pressure
present.
– Measured value (after pos. zero adjust) = 0.0 mbar
Options

Calib. offset (192) / (008)

Entry
Menu path:
Setup Calib. offset
Position adjustment – the pressure difference between the set point and the
measured pressure must be known.
Example:
– Measured value = 982.2 mbar (14.24 psi)
– You correct the measured value with the value entered (e.g. 2.2 mbar (0.032
psi)) via the "Calib. offset" parameter. This means that you are assigning the
value 980.0 (14.21 psi) to the pressure present.
– Measured value (after calib. offset) = 980.0 mbar (14.21 psi)
Factory setting:
0.0
