Empty height/
LEVEL_OFFSET_EASY
Entry/Display
Index: 95
Data type: FLOAT
Access: OOS
Enter the level, volume, mass or percentage value for the lower calibration point
(empty container).
The values entered for the Empty calibration/LOW_LEVEL_EASY and Empty
pressure/LOW_LEVEL_PRESSURE_EASY parameters form the pressure/level
value pair for the lower calibration point. The unit is selected via the Unit before
Lin./OUT_UNIT_EASY parameter (→ Seite 191).
Prerequisite:
• Level selection/LEVEL_ADJUSTMENT = in height or Primary Value/
PRIMARY_VALUE parameter is set to "Level height" or "Lev height+LinTab"
• Calibration mode/LEVEL_ADJUST_MODE_EASY = Dry
Factory setting:
0.0
Full height/
LEVEL_100_PERCENT_EASY
Entry/Display
Index: 96
Data type: FLOAT
Access: OOS
Enter the height, volume, mass or percentage value for the upper calibration
point (container full).
The values entered for the Full calib./HIGH_LEVEL_EASY and Full pressure/
HIGH_LEVEL_PRESSURE_EASY parameters form the pressure/level value pair
for the upper calibration point The unit is selected via the Unit before Lin./
OUT_UNIT_EASY parameter
(  ä 191).
Prerequisite:
• Level selection/LEVEL_ADJUSTMENT = in height or Primary Value/
PRIMARY_VALUE parameter is set to "Level height" or "Lev height+LinTab"
• Calibration mode/LEVEL_ADJUST_MODE_EASY = Dry
Factory setting:
100.0
Process density/
LEVEL_MEASUREMENT_DE
NSITY_EASY
Entry
Index: 97
Data type: FLOAT
Access: OOS
Enter a new density value for density correction.
The calibration was carried out with water as the medium, for example. Now the
container is to be used for another medium with another density. The
calibration is corrected appropriately by entering the new density value for the
Process density/LEVEL_MEASUREMENT_DENSITY_EASY parameter.
See also the Adjust density/LEVEL_ADJUST_DENSITY_EASY parameter.
Factory setting:
1.0
Meas. level/
MEASURED_ACTUAL_LEVEL
_EASY
Display
Index: 98
Data type: FLOAT
Access: read only
Displays the level currently measured.
The measured pressure is converted to a height using the Density unit/
DENSITY_UNIT_EASY and Adjust density/LEVEL_ADJUST_DENSITY_EASY
parameters.
Full calib./HIGH_LEVEL_EASY
Options
Index: 99
Data type: FLOAT
Access: OOS
Enter the height value for the upper calibration point (container full). Select the
unit via the Height unit/HEIGHT_UNIT_EASY parameter ( ä 190).
• In the case of wet calibration, the level (container full) must actually be
available. The associated pressure is then automatically recorded by the
device.
• In the case of dry calibration, the level (container full) does not have to be
available. The associated pressure has to be entered in the Full pressure/
HIGH_LEVEL_PRESSURE_EASY parameter for the "In pressure" level
selection. The associated height must entered in the Full height/
LEVEL_100_PERCENT_EASY parameter for the "In height" level selection.
