CALIBRATION
Note !
When connected to an IS15 system as per instructions, use the IS15 calibration
procedure.
The calibration is carried out using the following procedure:
1.
Switch on the autopilot to supply power to RC37, or use a separate switch if it is a
stand alone compass.
2.
Make two 360 degree turns to starboard within 5 minutes
after switch on. Ensure smooth and slow movements. A
minimum of roll and acceleration will give the best result.
Use 60-90 seconds each turn and make sure the boat passes
3 times through North (see figure). As soon as north is
passed for the 3rd time, there will be a confirmation in the
autopilot display (see below).
•
Provided you have an AP45 with software version V1R3 or V1R4 (latest), you
will read "Fluxgate compass compensated" in the info display when the
calibration is completed. Press the alarm button to reset. There will be no
confirmation in the display if the AP45 has a software revision earlier than V1R3.
•
On AP9Mk2 and Mk3 there are no verification codes. However, when passing
through north for the 3
rd
time, the course display shows 045 for a short moment
(less than a second).
