Press the
ADJUST
key. The display will
switch to show the current type of
compass selected.
This should be
already correct.
Press the
ADJUST
key. The display will
switch to 'C.AdJ'.
Press either the up or down
ARROW
key
to bypass the compass adjustment
routine. All adjustments have now been
turned off, and the raw compass
information is now shown on the display.
The compass adjuster can use this
display to adjust the compass manually.
After the compass adjuster is finished,
re-swing the vessel using the automatic
method described above to remove any
minor errors which may persist.
The ComNav Marine Fluxgate
Compass
, like most self compensating
compasses, removes the effect of the
deviating magnetic field, but does not
actually remove the field itself.
If the field is sufficiently large, when the
vessel rolls, the portion of the field in the
plane of the sensor changes, and is
interpreted as a turn by the compass,
causing the vessel to wander.
The compass adjuster, by placing
magnets around the compass removes
the deviating field itself from the vicinity
of the compass, resulting in much more
accurate steering in all sea conditions.
Place the vessel on a known heading.
If the reading on the autopilot display
disagrees with the vessels actual
heading, correct it with a permanent
heading offset.
To do this, place the master select switch
in the
STANDBY
position, press the
ADJUST
key twice to display the heading
offset, and adjust it up or down by the
amount of the error using the up or down
ARROW
keys.
The display will change back to show the
vessels heading in 5 seconds, which
should now be correct.
If the autopilot is using a ComNav
Fluxgate compass,
the final adjustment
is the heeling adjustment.
To access the heeling adjuster, remove
the screw from the top of the compass.
Reach in through the hole with a small
non-magnetic screwdriver to make an
adjustment.
This manual adjustment corrects for any
vertical magnetism in the vicinity of the
compass.
During the remainder of the sea trials, if
the vessel seems to wander on some
headings (particularly North or South)
while steering well on other headings,
turn the heeling adjustment clockwise or
counter-clockwise until wandering stops.
This adjustment may cause some
additional deviation in the compass, so
the compass should be re-swung using
the automatic method after any change
of the heeling adjustment.

The 1001 Autopilot offers
instant selection of pre-adjusted FAST
and SLOW vessel control settings.
Adjust or fine-tune these settings to
your vessel characteristics as follows:
