1 V9H5 e.g. 672 Reset transmitter, see Section 4.1 (default = operating mode 1)
- Enter probe constants at V3H5 and V3H6
2 V0H1/V0H2 - Calibrate as described in Section 4.2
3 V2H1 1 Select automatic entry of values
4 - »E« Register entry
5V2H21
…
30 Enter table entry number
6 - »E« Register entry
7 V2H3 e.g. 0 Fill vessel, enter volume in required units
8 - »E« Register entry
9 V2H4 - Display of current level
10 - »E« Automatically writes the level to the support point number
11 V2H5 2
…
30 Second support point number will be displayed
12 - »E« Confirm input, the system jumps to V2H3,
the support point number is addet automatically
13 V2H3 Repeat steps 7 to 12 until the filling volume and level
have been entered for all support points
14 V2H0 3 Select manual linearization table
15 - »E« Press »E« to activate linearization
16 V0H0/V0H9 - Display of volume and level before linearisation
Note!
• For this procedure the tank can be filled for calibration then emptied for linearization.
• Set analogue output and relay switch point 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.
