" (three digits) are displaying auto-compensation data (a "
000
" indicates that
the system has not been auto-compensated.)
A. The
first digit
(1-9) indicates the
quality of
the compensation
with "9" being the best.
B. The
second digit
(1-9) indicates the
quality
of the magnetic location
with "9" being the
best.
C. The
third digit
is a
rollover counter
incrementing 1 digit each time the Sailcomp
has accepted a new compensation.
For instance, if you got the above "
991
" it would indicates that you had a great com-
pensation (
9
), a great magnetic location (
9
) and that this is your first compensation (
1
)*.
If the first digit is lower than a "
7
", you should turn another 360° to try and get a better
compensation. If the second digit is lower than a "4", you may consider moving the
sensor to a better magnetic location. However, even with a 3 or lower, as long as the
first digit is a "
9
", you should have ±1° accuracy.
Note:
In rare cases, the magnetic field of a particular location may be so different from the fac-
tory calibration, that the sensor will re-compensate every 36° while doing a 360° turn. Do not
be alarmed if the compensation display shows that more than one compensation has taken place
or compensation takes place be-fore you complete a circle. J
ust make sure that you complete
at least one full, slow circle.
Multiple compensations are an indication that the sensor is
rapidly receiving better and better information and is updating its stored information for
greater accuracy.
If you ever significantly change your boat's latitude or make changes on your boat
(install new equipment, run cables, etc.)
which may affect the boat's magnetic field, or if
you are ever in doubt as to the Sailcomp 103AC's accuracy, simply follow the auto-
compensation procedure on pages 17-19 to be assured that it is accurate at all times.

the "Compensation Display" apply

short pushes to the
