Description
5 If density correction is required, assign the
temperature probe in the "Auto dens. corr."
parameter.
Menu path: Expertc → Application → Auto
dens. corr.
A density correction is only possible for water.
A temperature-density curve that is saved in
the device is used. For this reason, the "Adjust
density" (step 8) and "Process density" (step 13)
parameters are not used here.
6 Select a level unit via the "Output unit"
parameter, "m" for example.
Menu path: Setup → Extended setup → Level →
Output unit
7 Select the "Wet" option via the "Calibration
mode" parameter.
Menu path: Setup → Extended setup → Level →

8 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.
Menu path: Setup → Extended setup → Level →
Adjust density

The process density can be changed only
if automatic density correction is
switched off (see step 5).
9 The hydrostatic pressure for the lower
calibration point is present at the device, here
"0 mbar" for example.
Select the "Empty calib." parameter.
Menu path: Setup → Extended setup → Level →
Empty calib.
Enter the level value, here 0 m for example.
The pressure value present is assigned to the
lower level value by confirming the value.
10 The hydrostatic pressure for the upper
calibration point is present at the device, here
300 mbar (4.35 psi) for example.
Select the "Full calib." parameter.
Menu path: Setup → Extended setup → Level →
Full calib.
Enter the level value, 3 m (9.8 ft). The pressure
value present is assigned to the upper level
value by confirming the value.
11 Use the "Set LRV" parameter to set the level
value for the lower current value (4 mA), here
"0 m" for example.
Menu path: Setup → Extended setup → Current
output → Set LRV
12 Use the "Set URV" parameter to set the upper
current value (20 mA) (3 m (9.8 ft)).
Menu path: Setup → Extended setup → Current
output → Set URV
