Pos. zero adjust (007)
Navigation Setup → Pos. zero adjust
Write permission Operators/Service engineers/Expert
Description Position adjustment – the pressure difference between zero (set point) and the measured
differential pressure need not be known.
Options • Confirm
• Cancel
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.

9.10 Configuring level measurement
9.10.1 Information on level measurement
You have a choice of two methods for calculating the level: "In pressure" and "In
height". The table in the "Overview of level measurement" section that follows
provides you with an overview of these two measuring tasks.
• The limit values are not checked, i.e. the values entered must be appropriate for the
sensor module and the measuring task for the device to be able to measure
correctly.
• Customer-specific units are not possible.
• There is no unit conversion.
• The values entered for "Empty calib./Full calib.", "Empty pressure/Full pressure",
"Empty height/Full height" and "Set LRV/Set URV" must be at least 1% apart. The
value will be rejected, and a warning message displayed, if the values are too close
together.
