Fig. 31: Parameter adjustment example min./max. adjustment level measure-
ment
1 Min. level = 0 % corresponds to 0.0 mbar
2 Max. level = 100 % corresponds to 196.2 mbar
If these values are not known, an adjustment with levels of for exam-
ple 10 % and 90 % is also possible. By means of these settings, the
real filling height is then calculated.
The real product level during the adjustment is not important, because
the min./max. adjustment is always carried out without changing the
product level. These settings can be made ahead of time without the
instrument having to be installed.
Proceed as follows:
1. Select the menu item "Setup" with [->] and confirm with [OK].
Now select with [->] the menu item "Adjustment", then "Min.
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. 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.
