During this wet calibration, a level of 20% is used as the calibration point for "Empty" and a
level of "80%" is used as the calibration point for "Full".
The calibration is then extended to 0% to 100% and lower range-value (LRV)/upper
range-value (URV) are adapted accordingly.
Prerequisite:
• The default value in level mode for the calibration mode is "Wet".
• This value can be adjusted: Menu path: Setup → Extended setup → Level → Calibration
mode
Description
1 Select the "Level" measuring mode via the
"Measuring mode (005)" parameter.
Menu path: Setup → Measuring mode

2 Select a unit via the "Unit before lin. (025)"
parameter, here "%" for example.
Menu path: Setup → Extended setup → Level→
Unit before lin.
3 20% of the vessel is full. Enter the level value
for the lower calibration value via the "Empty
calib. (028)" parameter, here 20% for example.
Menu path: Setup → Extended setup → Level →
Empty calib.
4 80% of the vessel is full. Enter the level value
for the upper calibration value via the "Full
calib. (031)" parameter, here 80% for example.
Menu path: Setup → Extended setup → Level →
Full calib.
5 The pressure values for full/empty calibration
are automatically recorded and applied. The
upper range value (URV) and lower range
value (LRV) automatically accept the values
that were entered in "Empty calib. (028)" and
"Full calib. (031)". These automatically entered
values can be edited if necessary and, for
example, changed to a value ranging from 0 to
100%.
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 (035)" parameter. In
this case, you have to enter the various densities via the following menu path:
• Setup → Extended setup → Level → Adjust density (034) e.g. 1.0 kg/l for water)
• Setup → Extended setup → Level → Process density (035) e.g. 0.8 kg/l for oil)
