Calibration
The calibration is carried out on-site with a completely empty then a full tank. The
minimum level is chosen to be approx. 3% of the measuring range. This ensures that
compensation is not triggered when the probe is temporarily uncovered due to
turbulence etc..

Note!
•
If appropriate, perform linearization for channel 1, see Chapter 5.
•
Configure analogue outputs, see Chapter 6.
-
Output 2 follows the correction factor at V4H0
•
Configure limit switches, see Chapter 7.
-
Default is relay 1 level, relay 2 correction factor
-
Assign relay 2 to output 1 at V5H4 (= 1)
