1. Perform "position adjustment" →  43.
2. 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.
3. Select a pressure unit via the "Press. eng. unit" parameter, here "mbar" for example.
 Menu path: Setup → Press. eng. unit
4. Select the "In pressure" level mode via the "Level selection" parameter.
 Menu path: Setup → Extended setup → Level → Level selection.
5. If density correction is required, assign the temperature probe in the "Auto dens. corr."
parameter. A density correction is only possible for water. A temperature-density
curve that is saved in the device is used. For this reason, the "Adjust density" (step 8)
and "Process density" (step 13) parameters are not used here.
 Menu path: Expert → Application → Auto dens. corr.
6. Select a level unit via the "Output unit" parameter, here "m" for example.
 Menu path: Setup → Extended setup → Level → Output unit
7. Select the "Wet" option via the "Calibration mode" parameter.
 Menu path: Setup → Extended setup → Level → Calibration mode
8. If the calibration is performed with a medium other than the process medium, enter
the density of the calibration medium in the "Adjust density" parameter.
 Menu path: Setup → Extended setup → Level → Adjust density
The process density can be changed only if automatic density correction is switched
off (see step 5).
9. The hydrostatic pressure for the lower calibration point is present at the device, here
"0 mbar" for example. Select the "Empty calib." parameter. Enter the level value, here
0 m for example. By confirming the value, you assign the pressure value present to
the lower level value.
 Menu path: Setup → Extended setup → Level → Empty calib.
