"Rotation Angle X"- is the inclination angle of the sensor around the X axis when the
vehicle is stationary on a level plane. Sensors directed towards the inside have a positive
angle. This angle must not be > 5°; otherwise the counting accuracy is reduced.
Measure the sensor's angle of rotation (e.g. using a suitable smartphone app) and enter the
value measured.
