Although the compass calibration removes most of the alignment error, small errors
(a few degrees) may remain. Once you have completed the initial compass
calibration, you can make further adjustments to the alignment without having to
swing the compass again.
Check the heading reading against a number of known headings, plot a deviation
curve, and determine the heading alignment value that will give the lowest average
alignment error. You can then enter this value on the Heading Alignment screen, as
described above.
If the average heading error is more than 5°, check there are no items close to the
compass that could cause an unwanted magnetic influence. You should also consider
moving the fluxgate compass and performing the compass deviation correction
procedure again, circling more slowly and in more favorable conditions.
Aligning rudder bar
If the rudder reference transducer is fitted, use this procedure to align the rudder bar
on the Pilot Controller display:
1. Access the ALIGN RUDDER screen in Seatrial calibration:
i.
From Standby mode, hold down
to see the SEATRIAL CAL screen.
i.
Press
ALIGN RUDDER screen
2. Steer straight ahead then use
played rudder bar to zero.
AutoLearn
CAUTION:
When using Autolearn you must have significant clear water both in
front and to the sides of the vessel. This is needed to accommodate
a series of maneuvers, which include sudden, sharp turns.
The next stage of the Seatrial is to carry out an AutoLearn routine. This is a self-
learning calibration feature that automatically adjusts rudder gain, counter rudder and
AutoTrim for optimum performance on your boat.
If you need to return to manual steering at any time during an AutoLearn routine or any
other procedure, press the standby button. NEVER compromise vessel safety.
Clear water
The Autolearn set up feature performs a series of 7 or 8 turns at normal cruising
speed. The amount of clear water required depends upon the cruising speed of your
vessel.
For example:
•
Minimum 100 m wide and 500 m ahead (typical non-planing vessel at 6 kts).
•
Minimum 500 m wide and 2000 m ahead (typical planing vessel at 20 kts).
