Sea Trials; Calibrating The Compass; Aligning The Compass And The Rudder; Aligning The Compass (Align Heading) - NorthStar NS3300 AutoPilot Installation Manual

5 Sea trials

Perform the sea trials:
For the sea trials, sail in an open area where there are no other craft or obstructions. The sea should be calm, the
wind speed as low as possible and there should be no currents.

5-1 Calibrating the compass

Note
To calibrate the Compass unit go to Compass in the Setup > Calibrate menu. Follow the on-screen instructions
presented by the calibration wizard (See PILOT 3300 Reference manual).

5-2 Aligning the compass and the rudder

The compass or rudder can be aligned separately.

5-2-1 Aligning the compass (Align heading)

This aligns the PILOT 3300 system compass to display the correct heading.
The compass can be aligned either to a reference compass or to a GPS connected to the PILOT 3300 system. Ensure
there is no cross-wind or current.
To align the Compass unit go to Align heading in the Setup > Calibrate menu. Follow the on-screen instructions
presented by the calibration wizard (See PILOT 3300 Reference manual).

5-2-2 Aligning the Rudder (Centre rudder)

This sets the rudder setting to sail a straight course. Ensure there is no cross wind or current.
To align the rudder go to Centre rudder in the Setup > Calibrate menu. Follow the on-screen instructions
presented by the calibration wizard (See PILOT 3300 Reference manual).

After performing the dockside setup (see section 4).
To check the operation of the PILOT 3300 system.
To exit the calibration at any time, press ESC.
If the boat is not turned as prompted or the compass is not working then calibration can not be completed, the PILOT
3300 system displays an error. Press ESC, fix the problem and repeat the calibration.
Local disturbances in magnetic field may affect the compass. Calibration must be preformed away from large metal
structures such as marinas, large ships etc.; this is the responsibility of the user.
Ensure that both sources are referencing the same north (true or magnetic). If your magnetic compass has not been
calibrated then you can use another source for heading. If using vessel's compass then ensure that the deviation tables
are applied to check the autopilot's compass.
