Manually calibrating the sensor
Opening the battery circuit breaker switches off the electro
-
nics in the superstructure (see item: battery circuit breaker).
Now the sensor can calibrate itself. This process takes approx.
three hours. If the battery circuit breaker is then switched on
again, a value of “1” should be shown on the display.
