Endress+Hauser Liquicap M FMI51 HART - Operating Mode: Full Calibr. and Function - Wet; Operating Mode: Empty Calibr. and Function - Dry

Commissioning Liquicap M FMI51 HART
48 Endress+Hauser
Subfunction: "Confirm cal."
In this function, empty calibration is confirmed and the "Measure capacity" currently
measured is assigned to the percentage level value entered as "Value empty".
7.3.5 Operating mode: "Full calibr." and function - "Wet"
With "Full calibration", the 100% value or the 20 mA value is assigned to the level value.
The procedure applies to the "Wet" type of calibration. Information on "Dry" calibration
is provided further below.
Subfunction: "Value full"
The current level value is entered here, for example 90% partial filling → "Value full" 90%
or 100% filling → "Value full" 100%.
To keep the calibration error to a minimum, the level should be between 70% and
100%.
Subfunction: "Measure capacity"
The capacitance value currently measured is displayed here.
Subfunction: "Confirm cal."
Full calibration must be confirmed with this function.
7.3.6 Operating mode: "Empty calibr." and function - "Dry"
The "Empty" value can be entered directly in units of length if the medium property has
been set to conductive or nonconductive.
Subfunction: "Value empty ", medium property for the conductive and nonconductive
medium
