POSITION ADJUST function group
POS. ZERO ADJUST
Due to the orientation of the device, there may be a shift in the measured value, i.e. when the container is empty, the measured value does not display zero. Cerabar S, Deltabar S and Deltapilot S offer three different ways of performing a position adjustment.
Recommendation:
The pressure difference between zero (set point) and the measured pressure need not be known.
POS. ZERO ADJUST: Deltabar S, Cerabar S with gauge pressure sensor or Deltapilot S.
POS. INPUT VALUE: Cerabar S with absolute pressure sensor.
The pressure difference between zero (set point) and the measured pressure is known.
CALIB. OFFSET: Deltabar S, Cerabar S with gauge pressure sensor, Cerabar S with absolute pressure sensor or Deltapilot S.
POS.ZERO ADJUST:
Position adjustment - the pressure difference between zero (set point) and the measured pressure need not be known. (A reference pressure is present at the device.)
Example:
MEASURED VALUE = 2.2 mbar
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
The current value is also corrected.
The CALIB. OFFSET parameter displays the resulting pressure difference (offset) by which the MEASURED VALUE was corrected.

The pressure difference between zero (set point) and the measured pressure is known.
CALIB. OFFSET: Deltabar S, Cerabar S with gauge pressure sensor, Cerabar S with absolute pressure sensor or Deltapilot S.
POS. INPUT VALUE:
Position adjustment - the pressure difference between zero (set point) and the measured pressure need not be known. (A reference pressure is present at the device.)
Example:
MEASURED VALUE = 0.5 mbar
For the POS. INPUT VALUE parameter, specify the desired set point for the MEASURED VALUE, e.g. 2 mbar.
(MEASURED VALUEnew = POS. INPUT VALUE)
MEASURED VALUE (after entry for POS. INPUT VALUE) = 2.0 mbar
The CALIB. OFFSET parameter displays the resulting pressure difference (offset) by which the MEASURED VALUE was corrected.
CALIB. OFFSET = MEASURED VALUEold - POS. INPUT VALUE,
here: CALIB. OFFSET = 0.5 mbar - 2.0 mbar = - 1.5 mbar)
The current value is also corrected.
Factory setting:

CALIB. OFFSET:
Position adjustment - the pressure difference between zero (set point) and the measured pressure is known. (A reference pressure is not present at the device.)
Example:
MEASURED VALUE = 2.2 mbar
Via the CALIB. OFFSET parameter, enter the value by which the MEASURED VALUE should be corrected. To correct the MEASURED VALUE to 0.0 mbar, you must enter the value 2.2 here.
(MEASURED VALUEnew = MEASURED VALUEold - CALIB. OFFSET)
MEASURED VALUE (after entry for calib. offset) = 0.0 mbar
The current value is also corrected.
Factory setting:
