3.5 Automatic Deviation Correction
The ST6000 will correct the fluxgate compass for operation in most deviating
magnetic fields. This should be carried out in calm conditions preferably in flat water.
• To select compass adjust Push and hold Standby for 1 second.
Keeping boat speed below 2 knots, turn the vessel slowly so that it takes at least 3
minutes to complete 360°. Keep turning until control unit beeps, and the display
changes to show the amount of deviation the autopilot has corrected:-
Note: If the amount exceeds 15°, it is recommended the fluxgate should be re-sited.
• Use the course change buttons to adjust the displayed heading until it agrees with
the steering compass or a known transit bearing.
Note: 000° is always followed by OFF. This will suppress the display of compass and
automatic headings on the control unit.
• To exit compass adjust and store the compass settings push and hold Standby
for 1 second.
• To exit compass adjust without saving any new settings push Standby
momentarily.
