b) Semi-automatic
linearisation
After callibration, p. 26, the semi-automatic
linearisation can be made:
•
Enter known volume V/weight G in
V2H3/V6H3
•
Level is displayed in V2H4/V6H4

Deletion of value pairs
To delete a pair of values:
•
Enter table number in V2H2/V6H2
•
Enter 9999 in V2H3/V6H3 or V2H4/V6H4
Deletion of linearisation
There are two possibilities for deleting a
linearisation:
•
Enter "0" in V2H0/V6H0:
the linearisation is de-activated but the
table remains stored
— Enter 1 (horizontal cylinder) or
3 (linearisation table) to re-activate.
•
Enter "4" in V2H0/V6H0:
the manual or semi-automatic
linearisation is deleted, V2H0 = 0
— The linearisation for horizontal
cylinders is deactivated but remains
stored.
