COMPASS AUTOCOMPENSATION
On some boats, the Regatta Compass may be strongly disrupted by its environment.
Despite a careful installation and an offset properly adjusted, an important difference remains
between the magnetic heading displayed and the true magnetic heading, throughout the
measurement range between 0 and 359°. In this case, you can perform an autocompensation
of the Regatta Compass to achieve an acceptable level of accuracy.
2.1.5 Autocompensation principle
The operation consists in executing a perfect circle with your boat at a rigorously
constant speed. Thus, your Regatta Compass will be accurately corrected between 0 and
359°.
2.1.6 Autocompensation procedure for the Regatta Compass
In order to achieve a successful autocompensation, you must sail:
- On a smooth sea, with no current,
- Away from large magnetic masses such as cargo ships, buoys, metallic pontoons,…
- At a constant speed of about 2 or 3 knots.
1. Display the magnetic heading channel.
2. Launch the “autocompensation” mode according to the procedure described in the user
guide of your display.
3. Start to describe the circle then launch the autocompensation procedure.
4. One circle is enough to perform the autocompensation correctly.
5. The display then sends out a message to the user indicating that the autocompensation is
successful. The number 3 for the Gyropilot and the number 3000 alternately with dashes
for the other displays (Performance, TL25 and SL50).
6. Exit the autocompensation mode.
Please refer to the user guide of your display to perform the autocompensation procedure.
Should there be a problem during autocompensation, the display will notify the user of the
cause of the fault indicating alternately, for 5 seconds, the message PANNE with the following
code :
- code 11: Failure through timeout (> 5 minutes) or excessively slow rotation (< 30 sec / 45°).
- code 12: Failure through excessive heel.
- code 13: Any other error.
In case of autocompensation error, the measurements are not saved to the memory and the
sensor resumes its normal operating mode.
CAUTION: the autocompensation operation of the Regatta Compass requires precision in
the execution of the circle: it must be done in less than 5 minutes at a constant speed of 2
to 3 knots. If you cannot maintain these two criteria, the autocompensation will not be
successful.
