Pos. Zero Adjust (007)
Navigation Expert → Measurement → Basic Setup → Pos. Zero Adjust (007)
Write permission Operators/Service engineers/Expert
Description 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)
• 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 adjust) = 0.0 mbar
• The current value is also corrected.
Options • Confirm
• Cancel
Factory setting Cancel
Calib. Offset (008)
Navigation Expert → Measurement → Basic Setup → Calib. Offset (008)
Write permission Service engineers/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 980.0 (14.7
psi) to the pressure present.
• Measured value (after pos. zero adjust) = 980.0 mbar (14.7 psi)
• The current value is also corrected.
Factory setting 0.0
Empty Calib. (011/28)
Navigation Expert → Measurement → Level → Empty Calib. (011/028)
Write permission Operators/Service engineers/Expert
Description Enter the output value for the lower calibration point (vessel empty). The unit defined in
"Unit Before Lin." must be used.
