Calibration without reference pressure (dry calibration)
1 See table, Step 12.
2 See table, Step 8.
3 See table, Step 9.
4 See table, Step 10.
5 See table, Step 11.
9 Enter the volume value for the upper calibration point
via the "Full calib." parameter ( ä 115), here "1000
liter" (264 US gal) for example.
Menu path: Setup  Extended setup  Level 
Full calib.
10 Enter the volume value for the lower calibration point
via the "Empty calib." parameter ( ä 115), here
"0 liter" for example.
Menu path: Setup  Extended setup  Level 
Empty calib.
11 Enter the height value for the upper calibration point via
the "Full height" parameter ( ä 115), here "4 m" (13
ft) for example.
Menu path: Setup  Extended setup  Level 
Full height
12 Enter the density of the medium, using the "Adjust
density" parameter ( ä 115), here 1 g/cm
3
(1 SGU)
for example.
Menu path: Setup  Extended setup  Level 
Adjust density
13 Result:
The measuring range is set for 0 to 1000 l (264 US gal).
0 l corresponds to an output current of 4 mA.
1000 l (264 US gal) corresponds to an output current of
20 mA.
