8 Enter the height value for the lower calibration point via
the "Empty height" parameter, here 0.5 m (1.6 ft) for
example.
Menu path: Setup  Extended setup  Level  Empty
height
9 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.
10 Enter the height value for the upper calibration point via
the "Full height" parameter, here 4.5 m (15 ft) for
example.
Menu path: Setup  Extended setup  Level  Full
height
11 Enter the density of the medium via the "Adjust density"
parameter, here "1 g/cm
3
" (1 SGU) for example.
Menu path: Setup  Extended setup  Level  Adjust
density
12 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
13 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
14 If the process uses a medium other than that on which
the calibration was based, the new density has to be
specified in the "Process density" parameter.
Menu path: Setup  Extended setup  Level 
Process density
15 Result:
The measuring range is set for 0 to 1000 l (264 US gal).
