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.

10.7 Configuring level measurement
10.7.1 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.
