2. Edit the percentage value with [OK] and set the cursor to the
requested position with [->].
3. Set the requested percentage value (e.g. 10 %) with [+] and save
with [OK]. The cursor jumps now to the pressure value.
4. Enter the pressure value corresponding to the min. level (e.g.
0 mbar).
5. Save settings with [OK] and move with [ESC] and [->] to the max.
adjustment.
The min. adjustment is finished.
For an adjustment with filling, simply enter the actual measured value
indicated at the bottom of the display.

To damp process-dependent measured value fluctuations, set an
integration time of 0 … 999 s in this menu item. The increment is 0.1 s.
Depending on the sensor type, the factory setting is 0.1 s.
A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. a horizontal cylindri-
cal or spherical tank - and the indication or output of the volume is
