Parameter name Description
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. Deltabar S, Cerabar 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 or Cerabar S with gauge pressure sensors or Deltapilot S.
– POS. INPUT VALUE: Cerabar S with absolute pressure sensors.
• The pressure difference between zero (set point) and the measured pressure is known.
– CALIB. OFFSET: Deltabar S, Cerabar S with gauge pressure sensors, Cerabar S with absolute pressure sensors or
Deltapilot S.
POS. ZERO ADJUST (685)
Entry
Position adjustment – the pressure difference between zero (set point) and the measured
pressure need not be known.
Example:
– MEASURED VALUE = 2.2 mbar (0,033 psi)
– 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 CALIB. OFFSET parameter displays the resulting pressure difference (offset) by which
the MEASURED VALUE was corrected.
