Corrected press. (172)
Navigation Setup → Corrected press.

Description 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) (gauge pressure sensors))
Write permission Operator/Maintenance/Expert
Description Pos. 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
are assigning the value 0.0 to the pressure present.
• Measured value (after pos. zero adjustment) = 0.0 mbar
• The current value is also corrected.
