Description Select the calibration mode.
Options • Wet
Wet calibration takes place by filling and emptying the vessel. In the case of two
different levels, the level, volume, mass or percentage value entered is assigned to the
pressure measured at this point in time ("Empty Calib." and "Full Calib." parameters).
• Dry
Dry calibration is a theoretical calibration. For this calibration, you specify two pressure-
level value pairs or height-level value pairs via the following parameters: "Empty Calib.",
"Empty Pressure", "Empty Height", "Full Calib.", "Full Pressure", "Full Height".

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. 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.
Factory setting 0.0
Empty Pressure (029)/(185)
