Factory setting:
mbar or bar depending on the sensor nominal measuring range, or as per order specifications
Parameter name Description
Corrected press.

Display
Menu path:
Setup → Corrected
press.
Displays the measured pressure after sensor trim and position adjustment.
!
Note!
If this value is not equal to "0", it can be corrected to "0" by the position adjustment.
Pos. zero adjust (007)
Selection
Menu path:
Setup → Pos. zero adjust
Position zero 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)
– You correct the measured value via the "Pos. zero adjust" parameter with the "Confirm"
option. This means that you assign the value 0.0 to the pressure present.
– Measured value (after pos. zero adjust) = 0.0 mbar
– The current value is also corrected.
Options
•Confirm
• Abort
Factory setting:
Abort
