7 Select a height unit via the "Height unit"
parameter, here "m" for example.
Menu path: Setup → Extended setup → Level →
Height unit
8 Select the "Wet" option via the "Calibration
mode" parameter.
Menu path: Setup → Extended setup → Level →
Calibration mode
9 The hydrostatic pressure for the lower
calibration point is present at the device, here
"0 mbar" for example.
Enter the volume value for the lower
calibration point via the "Empty calib."
parameter, here "0 liter" for example.
Menu path: Setup → Extended setup → Level →
Empty calib.
10 The hydrostatic pressure for the upper
calibration point is present at the device, here
"400 mbar (6 psi)" for example.
Enter the volume value for the upper
calibration point via the "Full calib." parameter,
here 1 000 l (264 gal) for example.
Menu path: Setup → Extended setup → Level →
Full calib.
11 If the 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

The process density can only be changed
if automatic density correction is
switched off (see Step 4).
12 Set the volume value for the lower current
value (4 mA) via the "Set LRV" parameter (0 l).
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(1 000 l (264 gal)).
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 must be specified in the "Process
density" parameter.
Menu path: Setup → Extended setup → Level →
Process density.

The process density can only be changed
if automatic density correction is
switched off (see Step 4).
15 Result:
The measuring range is configured for
0 to 1 000 l (0 to 264 gal).
