In this menu item you can select the function of the first Function

With this you can adjust the value for the Primary Value (PV). Further
settings (SV, TV) must be carried out via PACTware.
The quick setup is finished.
VEGADIF 85 always measures pressure independently of the process
variable selected in the menu item " Application ". To output the se-
lected process variable correctly, an allocation of the output signal to
0 % and 100 % must be carried out (adjustment).
When using the application "
Level ", the hydrostatic pressure, e.g.
with full and empty vessel, is entered as adjustment value. A super-
imposed pressure is detected by the minus side and automatically
compensated. See the following example:

Fig. 7: Parameter adjustment example Min./max. adjustment, level measure-
ment
1 Min. level = 0 % corresponds to 0.0 mbar
2 Max. level = 100 % corresponds to 490.5 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.
