Automatic compass deviation correction
The ST6000 Plus will correct the fluxgate compass for most deviating
magnetic fields. Compass errors due to deviating magnetic fields can
be up to 15°, depending on your vessel type. The correction procedure
reduces these to a few degrees, so it is essential to perform the
procedure as the first item in your initial sea trial.
CAUTION:
Failure to carry out the deviation correction may result in
impaired autopilot performance on some compass headings.
To allow the system to determine the deviation and calculate any
correction required, you must turn your vessel in slow circles. This
procedure must be carried out in calm conditions and preferably in flat
water.
To perform the deviation correction:
1. Make sure that the autopilot is in Standby mode .
2. Press and hold the
standby
key for 2 seconds to display the User
Setup entry page.
