Prerequisite:
• The measured variable is in direct proportion to the pressure.
• This is a theoretical calibration i.e. the pressure and volume values for the lower and
upper calibration point must be known.
• The values entered for "Empty calib./Full calib.", "Empty pressure/Full pressure" and
"Set LRV/Set URV" must be at least 1% apart. The value will be rejected, and a
message displayed, if the values are too close together. Further 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.
• Due to the orientation of the device, there may be pressure shifts in the measured
value, i.e. when the vessel is empty or partly filled, the measured value is not zero.
For information on how to perform position adjustment, see →  43.

1. Select the "Level" measuring mode via the "Measuring mode" parameter.
 Menu path: Setup → Measuring mode
L
WARNING
Changing the measuring mode affects the span (URV)
This situation can result in product overflow.
‣
If the measuring mode is changed, the setting for the span (URV) must be checked in
the "Setup" operating menu and readjusted if necessary.
2. Select a pressure unit via the "Press. eng. unit" parameter, here "mbar" for example.
 Menu path: Setup → Press. eng. unit
3. Select the "In pressure" level mode via the "Level selection" parameter.
 Menu path: Setup → Extended setup → Level → Level selection
4. Select a volume unit via the "Output unit" parameter, here "l" (liters) for example.
 Menu path: Setup → Extended setup → Level → Output unit
5. Select the "Dry" option via the "Calibration mode" parameter.
 Menu path: Setup → Extended setup → Level → Calibration mode
6. Enter the volume value for the lower calibration point via the "Empty calib."
parameter, here 0 liters for example.
 Menu path: Setup → Extended setup → Level → Empty calib.
7. Enter the pressure value for the lower calibration point via the "Empty pressure"
parameter, here "0 mbar" for example.
 Menu path: Setup → Extended setup → Level → Empty pressure
