Compass Calibration
The standard TMQ compass
(COMMAG or E-Compass) supplied
as part of the AP56 autopilot system
has been calibrated after manufacture
and this calibration will be satisfactory
for most 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.
NOTE:
The calibration should only be
done if the compass is known to be
inaccurate when compared to a chart
bearing.
If the AP56 compass heading
displays a constant offset when
compared to a correctly calibrated
ships compass (eg: the autopilot
compass reads 3 degrees high on all
headings), simply rotate the compass
sensor to align the displayed
headings with the ships compass.
In this case it is not necessary to
re-calibrate the compass as
described below.
If the AP56 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. AUTO mode must not be
selected to carry out the calibration.
To calibrate compass:
•
Press MODE button eight times
• Display will read CCAL
•
Press ◄ and ► together to start
calibration
• Display will read StrC
• Commence turning the boat slowly
in one direction for two full circles
(720º). Each circle should take a
minimum of 1 minute.
• On completion of the turns press
◄ and ► together to store the
calibration.
• Display will revert to read heading
• Check the compass alignment by
steering boat due north 000º by
boat’s compass
• Rotate autopilot compass (if
necessary) so that display also
reads 000
NOTE:
The effectiveness of the
compass calibration is dependent upon
all steps being completed. Should you
wish to abort the calibration procedure
at any time during the process, simply
press MODE button to return the pilot
to MANUAL.
