Calibration of the sensor
The sensor can be calibrated using three different methods:
When typing in the active wire length and the distance between the fins the basic calibration is calculated, and the
sensor is working, but the accuracy can be improved by making a zero calibration. The calibration is always done when
the evaporator is dry and without significant ice
Using the green button in the box
Press the green button until the red LED turn off
Press the green button once and the calibration is done
Using the HB-tool

Calibration - when using the thin wire
When the sensor is installed and the evaporator is dry
and without ice, connect the sensor to the HB-tool
using a USB cable.
