CALIBRATION MODE (392)
Selection
Select the calibration mode for the calibration of the 1st measured variable.
Options:
• Wet
Wet calibration takes place by filling the container. This calibration mode requires two
pressure-level value pairs to be entered. In the case of two different levels, the level
value is entered and the pressure measured at this moment is assigned to the level
value.
See also the following parameter description for EMPTY CALIB., EMPTY
PRESSURE, FULL CALIB. and FULL PRESSURE.
• Dry
Dry calibration is a theoretical calibration which you can carry out even if the device is
not mounted or the container is empty.
– For the "Level" measured variable, the density of the fluid (
see Page 88, ADJUST
DENSITY) must be entered.
– For the "%" measured variable, the density of the fluid must be entered and a level
assigned to the 100 % point (
see Page 88, ADJUST DENSITY and 100% POINT).
If the measurement should not start at the mounting location of the device, a level
offset must be entered (
!
Note!
If the change to dry calibration is made after a wet calibration, the density must be
entered correctly using the ADJUST DENSITY and DENSITY PROCESS parameter before
changing the calibration mode.

Factory setting:
Wet
EMPTY CALIB. (314)
Entry
Enter level value for the lower calibration point (container empty).
The container is either empty or part full. By entering a value for this parameter, you are
assigning a level value to the pressure present at the device.
See also EMPTY
PRESSURE.
Prerequisite:
• CALIBRATION MODE = Wet
Factory setting:
0.0
EMPTY PRESSURE (710)
Display
Displays the pressure value for the lower calibration point (container empty).
See also EMPTY CALIB.
Prerequisite:
• CALIBRATION MODE = Wet
FULL CALIB. (315)
Entry
Enter level value for the upper calibration point (container full).
The container is either completely or almost full. By entering a value for this parameter,
you are assigning a level value to the pressure present at the device.
See also FULL
PRESSURE.
Prerequisite:
• CALIBRATION MODE = Wet
Factory setting:
100.0
FULL PRESSURE (711)
Display
Displays the pressure value for the upper calibration point (container full).
See also FULL CALIB.
Prerequisite:
• CALIBRATION MODE = Wet
Factory setting:
High sensor limit (
see PRESS. SENS HILIM, Page 119)
ADJUSTED DENSITY (810)
Display
Displays the density calculated from the upper and lower level point.
Prerequisite:
• COMB. MEASURAND = Height and Volume, CALIBRATION MODE = Wet
• COMB. MEASURAND = Height and Mass, CALIBRATION MODE = Wet
• COMB. MEASURAND = Height and %, CALIBRATION MODE = Wet
