Simrad AP27, AP26 manual Compass calibration

Simrad AP26 and AP27 Autopilots

Compass calibration

This function will activate the compass calibration procedure for Simrad compasses connected to Robnet2 and the Autopilot Computer terminals (HS).

Notes !

1.The RC36 Rate Compass that comes with the autopilot as standard will store the calibration and off-set data in its own memory.

2.Compass calibration for a second compass connected to the HS terminal will be stored in the Autopilot Computer memory.

3.Calibration is made on the compass that is active for the autopilot. The active compass is the one that is displayed on the compass calibration screen.

RATE-0 = Rate compass, FLUX-0 = Fluxgate compass on HS terminals.

4.If an optional NMEA compass from Simrad or another manufacturer is installed, also refer to the optional compass’ manual regarding calibration. This compass will not be calibrated by the autopilot.

Before you start the compass calibration, make sure you have enough open water around you to make a full turn with the boat.

The calibration should be done in calm sea conditions and with minimal wind to obtain good results. Use about 60-90 seconds to make a full circle.
