b) Semi-automatic
linearisation
After calibration, p. 26, the semi-automatic
linearisation can be made:
•
Enter known volume V/weight G in V2H3
•
Level is displayed in V2H4
No. Matrix Entry Remarks
5 V2H1 1 Semi-automatic
6 - »E« Register entry
7 V2H2 1 Table no.

Note!
•
On error E602 or E604, correct table. Re-activate linearisation in V2H0.
After linearisation
•
Volume/weight is displayed at V0H0
•
Level is displayed at V0H9
•
Density correction, p. 29.

Deletion of value pairs To delete a pair of values:
•
Enter table number in V2H2
•
Enter 9999 in V2H3 or V2H4
Deletion of linearisation There are two possibilities for deleting a
linearisation:
•
Enter "0" in V2H0: 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: the manual or
semi-automatic linearisation is deleted,
V2H0 = 0
— The linearisation for horizontal
cylinders is deactivated but remains
stored.
