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

Description Enter the output value for the lower calibration point (container empty). The unit defined in "Unit
Before Lin." must be used.
Note • In the case of wet calibration, the level (container empty) must actually be available. The associated
pressure is then automatically recorded by the device.
• In the case of dry calibration, the level (container empty) does not have to be available. The
associated pressure has to be entered in the "Empty Pressure (029)" parameter for the "In pressure"
level selection. The associated height has to be entered in the "Empty height" (030) parameter for
the "In height" level selection.
