1 See Table, Steps 8 and 9.
2 See Table, Step 10.
3 See Table, Step 11.
4 See Table, Step 12.
5 See Table, Step 13.
5 Select a volume unit via the OUTPUT UNIT parameter,
here l (liters) for example.
6 Select a height unit via the HEIGHT UNIT parameter,
here m for example.
7 Select the "Dry" option by means of the CALIBRATION
MODE parameter.
8 Select a density unit via the DENSITY UNIT parameter,
here kg/dm
3
for example.
9 Enter the density of the fluid using the ADJUST
DENSITY parameter, here 1 kg/dm
3
for example.
10 Enter the volume value for the lower calibration point
via the EMPTY CALIB. parameter, here 0 l (liters) for
example.
11 Enter the height value for the lower calibration point via
the EMPTY HEIGHT parameter, here 0.5 mbar (1.6 ft)
for example.
12 Enter the volume value for the upper calibration point
via the FULL CALIB. parameter, here 1000 l (liters) (264
US gal) for example.
13 Enter the height value for the upper calibration point via
the FULL HEIGHT parameter, here 4.5 mbar (0,0675
psi) for example.
14 Result:
The measuring range is set for 0 to 1000 l (liters) (264
US gal).
