Fig. 31: Calibrating the 1st measured variable
1 See Table, Step 11.
2 See Table, Step 12.
3 See Table, Step 14.
4 See Table, Step 15.
6 Select a pressure unit via the PRESS. ENG. UNIT
parameter, here mbar for example.
7 Select the "Height linearized" option by means of the
LEVEL MODE parameter.
8 Select the "Height + volume" option by means of the
COMB. MEASURAND parameter.
9 Select the unit for the 1st measured value via the
HEIGHT UNIT parameter, here m for example.
10 Select the unit for the 2nd measured variable via the
UNIT VOLUME parameter, here m
3
for example.
11 Select the LEVEL MIN parameter.
Enter the minimum level to be expected, here 0 m for
example.
12 Select the LEVEL MAX
parameter.
Enter the maximum level to be expected, here 3 m (9.8
ft) for example. See also Point 3 in the following note.
13 Select the "Wet" option via the CALIBRATION MODE
parameter (calibration mode for the 1st measured
variable).
14 The pressure for the lower calibration point is present at
the device, here 0 mbar for example.
Select the EMPTY CALIB. parameter.
Enter the level value, here 0 m for example. The
pressure value present is assigned to the lower level
value by confirming the value.
15 The pressure for the upper calibration point is present at
the device, here 300 mbar (4.5 psi) for example.
Select the FULL CALIB. parameter.
Enter the level value, here 3 m (9.8 ft) for example. The
pressure value present is assigned to the upper level
value by confirming the value.
16 Result:
The calibration for the 1st measured variable is carried
out.
Perform linearization (calibration for the 2nd
measured variable)
17 Change the function group.

18 Select the TANK CONTENT MIN parameter.
Specify the minimum tank contents to be expected, here
0 m
3
for example.
19 Select the TANK CONTENT MAX parameter .
Specify the maximum tank contents to be expected, here
5 m
