Parameter adjustment
• Adjust in the menu item "Adjustment“ the
unit "m“.
• Enter in the menu item "0 % at m…“ and
"100 % at m…“ the values 0.00 and 0.30 (if
30 cm should correspond to 100 %).
Only carry out the offset correction at this
point when both sensors are unpressurised.
If you want to carry out the adjustment in mA
or bar, you have to enter the difference val-
ues of the sensor currents or the pressures.
If you want that the gauge difference of 30
cm is shown in the meas. value indication in
cm, you can carry out a scaling (see "7.4
Scaling“).
Adjustment with level measurement in
pressurized vessels
For the adjustment of measurement loop
TAG1 (level) you can proceed in the same
manner as for the adjustment of a single
measurement loop. The adjustment can be
either carried out with or without medium
(product).
Measurement loop TAG2 (gauge pressure) is
adjusted without medium, preferably in "bar“.
For level measurement (TAG1), an adjust-
ment of TAG2 is not necessary.
Also, the adjustment of measurement loop
TAG3 (total pressure) must not be carried out
if you only want to know the level of TAG1.
Often, the total pressure is requested as
measured value, if e.g. in a filling system, the
filling pressure should be measured and
controlled. In this case carry out the adjust-
ment without medium in "bar“.
Adjustment with level difference and
pressure difference
The adjustment with this linked measurement
corresponds to that of the adjustment with
gauge difference and is therefore not de-
scribed separately.
