5
Select a volume unit via the OUTPUT UNIT parameter,
here l (litres) for example..
6
Select the "Dry" option by means of the CALIBRATION
MODE parameter.
7
Enter the volume value for the lower calibration point
via the EMPTY CALIB. parameter, here 0 l for example.
8
Enter the pressure value for the lower calibration point
via the EMPTY PRESSURE parameter, here 50 mbar
(0.75 psi) for example.
9
Enter the volume value for the upper calibration point
via the FULL CALIB. parameter, here 1000 l (264 gal)
for example.
10
Enter the pressure value for the upper calibration point
via the FULL PRESSURE parameter, here 450 mbar
(6.75 psi) for example.
11
Set the value for the lower current value (4 mA) by
means of the SET LRV parameter.
12
Set the value for the upper current value (20 mA) by
means of the SET URV parameter.
13
Result:
The measuring range is set for 0 to 1000 l (264 gal).
