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.
If the adjustment ranges are exceeded, then the entered value will not
be taken over. Editing can be interrupted with [ESC] or corrected to a
value within the adjustment ranges.
Proceed as follows:
1. Select with [->] the menu item max. adjustment and confirm with
[OK].
2. Edit the percentage value with [OK] and set the cursor to the
requested position with [->].
3. Set the requested percentage value (e.g. 90 %) with [+] and save
with [OK]. The cursor jumps now to the pressure value.
4. Enter the pressure value for the full vessel (e.g. 900 mbar) suit-
able for the percentage value.
5. Save settings with [OK]
The max. adjustment is finished.
For an adjustment with filling, simply enter the actual measured value
indicated at the bottom of the display.
If the adjustment ranges are exceeded, then the entered value will not
be taken over. Editing can be interrupted with [ESC] or corrected to a
value within the adjustment ranges.
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
