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 " 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 m3 for example.
11
Select LEVEL MIN parameter.
Enter the minimum level to be expected, here 0 m for
example.
12
Select LEVEL MAX parameter.
Enter the maximum level to be expected, here 3 m (9.8
ft) for example.
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 EMPTY CALIB. parameter.
Enter the level value, here 0 m for example. Confirm the
value to assign the pressure value present to the lower
level value.
15
The pressure for the upper calibration point is present at
the device, here 300 mbar (4.5 psi) for example.
Select FULL CALIB. parameter.
Enter the level value, here 3 m (9.8 ft) for example.
Confirm the value to assign the pressure value present to
the upper level value.
16
Result:
The calibration for the 1st measured variable is carried
out.
