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.
Selection • Confirm
• Cancel
Factory setting Cancel
Calib. offset (192) / (008) (absolute pressure sensor)
Write permission Maintenance/Expert
Description Position adjustment – the pressure difference between the
set point and the measured pressure must be known.
Example • Measured value = 982.2 mbar (14.73 psi)
• You correct the measured value with the value entered,
e.g. 2.2 mbar (0.033 psi) via the "Calib. offset" parameter.
This means that you are assigning the value to the
pressure present 980.0 mbar (14.7 psi).
• Measured value (after pos. zero adjustment) =
980.0 mbar (14.7 psi)
• The current value is also corrected.
Factory setting 0.0
