For the best results, install the sensor parallel to the rudder stock, so the sensor turns exactly as much as the rudder stock and the sensor's reading is at its most accurate. When installing, ensure that the physical zero position of the rudder and the physical zero position of the sensor coincide. NB! The rudder's zero position may not always be the ideal zero position for the vessel's course, and small deviations can be corrected later via software. After the autopilot is first switched on, check if the sensor's reading on the autopilot's display moves in the correct direction.

When installing, ensure that the physical zero position of the rudder and the physical zero position of the sensor coincide. NB!
