Description of Device Parameters Deltabar FMD71, FMD72
82 Endress+Hauser
Navigation Setup → Pos. zero adjust (007)

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 position adjustment) = 0.0 mbar
• The current value is also corrected.
Options • Confirm
• Cancel
Factory setting Cancel
Empty calib. (011/028)
Navigation Setup → Extended setup → Level → Empty calib. (011/028)

Description Enter the output value for the lower calibration point (vessel empty). The unit defined in
"Unit before lin." must be used.
Note • In the case of wet calibration, the level (vessel empty) must actually be available. The
associated pressure is then automatically recorded by the device.
• In the case of dry calibration, the level (vessel empty) does not have to be available. For
the "In pressure" level selection, the associated pressure must be entered in the "Empty
pressure (029)" parameter. The associated height has to be entered in the "Empty height"
(030) parameter for the "In height" level selection.
Factory setting 0.0
Full calib. (012/031)
Navigation Setup → Extended setup → Level → Full calib. (012/031)
Write permission Operators/Service engineers/Expert
Description Enter the output value for the upper calibration point (vessel full). The unit defined in "Unit
before lin." must be used.
