Heading Sensor Error After Software Upgrade

aurora37,

The autopilot control head software's message Detecting Magnetics is meant to be a visual indication to the operator that the autopilot system has not yet been able to determine the deviation field sensed by the EV-1/2 Sensor Core. The deviation field is determined by the autopilot by taking the autopilot for a relatively short cruise per the information found here. Until completion of detecting deviation, the autopilot control head will display a progress bar with red or green indicator to aid the operator in identifying whether the vessel's speed and rate of turn (slower is better) is appropriate for detecting sensed deviation.
