6 Select a level unit via the "Height unit" parameter,
here "m" for example.

A0031029
7 Select the "Wet" option via the "Calibration mode"
parameter.
Menu path: Setup  Extended setup  Level 
Calibration mode
8 The pressure for the lower calibration point is
present at the device, here "50 mbar" (0.75 psi) for
example.
Enter the volume value for the lower calibration
point via the "Empty calib." parameter, here 0 liters
for example. (The pressure currently measured is
displayed as the height, here 0.5 m (1.6 ft) for
example.)
Menu path: Setup  Extended setup  Level 
Empty calib.
9 The pressure for the upper calibration point is
present at the device, here "450 mbar" (6.75 psi) for
example.
Enter the volume value for the upper calibration
point via the "Full calib." parameter, here "1000
liters" (264 US gal) for example. The pressure
currently measured is displayed as the height, here
"4.5 m" (15 ft) for example.
Menu path: Setup  Extended setup  Level 
Full calib.
8 If calibration is performed with a medium other
than the process medium, enter the density of the
calibration medium in the "Adjust density"
parameter, here
"1 g/cm
3
" (1 SGU) for example.
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 
