1 See Table, Step 6.
2 See Table, Step 7.
3 See Table, Step 8.
4 See Table, Step 9.
5 See Table, Step 11.
6 See Table, Step 12.
6 Enter the volume value for the lower calibration point
via the "Empty calib." parameter, here 0 liters for
example.
Menu path: Setup  Extended setup  Level  Empty
calib.
7 Enter the pressure value for the lower calibration point
via the "Empty pressure" parameter, here 50 mbar (0.75
psi) for example.
Menu path: Setup  Extended setup  Level  Empty
pressure
8 Enter the volume value for the upper calibration point
via the "Full calib." parameter, here 1000 liters (264 US
gal) for example.
Menu path: Setup  Extended setup  Level  Full
calib.
9 Enter the pressure value for the upper calibration point
via the "Full pressure" parameter, here 450 mbar (6,75
psi) for example.
Menu path: Setup  Extended setup  Level  Full
pressure
10 "Adjust density" contains the factory setting 1.0 but this
value can be changed if required. The value pairs
subsequently entered must correspond to this density.
Menu path: Setup  Extended setup  Level  Adjust
density
11 Set the volume value for the lower current value (4 mA)
via the "Set LRV" parameter.
Menu path: Setup  Extended setup  Current output
 Set LRV
12 Set the volume value for the upper current value
(20 mA) via the "Set URV" parameter.
Menu path: Setup  Extended setup  Current output
 Set URV
13 If calibration was performed with a medium other than
the process medium, specify the density of the process
medium in the "Process density" parameter.
Menu path: Setup  Extended setup  Level 
Process density
14 Result:
The measuring range is set for 0 to 1000 l (264 US gal).
