selected process variable correctly, an allocation of the output signal
to 0 % and 100 % must be carried out (adjustment).
During adjustment, the pressure is entered e.g. for the level with full
and empty vessel, see following example:

Fig. 19: 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 filling levels of e.g.
10 % and 90 % is also possible. By means of these settings, the real
filling height is then calculated.
The actual 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.
Note:
If the adjustment ranges are exceeded, the entered value will not be
accepted. Editing can be interrupted with
[ESC]
or corrected to a
value within the adjustment ranges.
Proceed as follows:
1. Select the menu item "

" with
[->]
and confirm with
[OK]
.
Now select with
[->]
the menu item "

" and confirm with
[OK]
.
2. Edit the percentage value with
[OK]
and set the cursor to the
requested position with
