Onwa Marine Electronics KAP-866 - Manual (Page 20)

2.2.5 Auto Heading Adjust
The compass has been calibrated during manufacture. This calibration will be
satisfactory for almost all installations. If you have a steel vessel, or some
other factor which causes the compass to perform poorly, the calibration
procedure will adjust compass characteristics to compensate.
The calibration should only be done if the compass is known to be inaccurate.
If the KAP-866 display as constant offset (e.g. The compass reads 3 degrees
high on all bearings), simply rotate the Fluxgate Sensor case to align bearings
with the ships compass. It is not necessary to re-calibrate the compass as desc-
ribed below.
If the KAP-866 has inconsistent variation on different headings, the following
calibration procedure can be carried out. This procedure should only be done
in calm waters with adequate sea room.
