Note!
•
For this procedure the tank can be filled for calibration then emptied for linearization.
•
If a volume calibration is performed, Section 4.3, then the value displayed at field
V2H4 is a »volume« not a level.
•
Set analogue output in same units as used for linearization
Corrections to manual
linearization
An incorrect entry can be overwritten by selecting the appropriate table number at V2H2
and entering the new value at V2H3 or V2H4.
•
If 9999 is entered, the entire point is deleted from the characteristic.
•
On activation the linearization is resorted and subjected to a plausibility check.
