Chapter 3: Calibration

CAUTION:

If you fail to complete calibration, the performance of the Smart

Heading System will be impaired on some compass headings.

This chapter explains how to calibrate the Smart Heading System using a

Pathfinder Plus display. This chapter contains the following sections:

Note: The Pathfinder Plus display must contain software release 2

(or later) to enable the compass calibration feature. Contact your

Raymarine dealer if you need more information or a software upgrade.

Note: You can also calibrate the compass system using a Raymarine

autopilot (see the Appendix).

3.1 Compass calibration overview

When you have completed installation, you must take the boat on a short

seatrial to calibrate the Smart Heading System. This involves:

• linearising the compass – to reduce errors caused by deviating

magnetic fields on your boat

• aligning the heading – so the heading from the Smart Heading System

matches a known reference

You should only perform the initial seatrial:

• in conditions of light wind and calm water

• in waters that are clear of any obstructions, so the boat has plenty of

clear space to maneuver

Note: If you have a GPS connected to your Pathfinder Plus, make sure

you switch it on so you can align your compass heading to COG (course

over ground).

CAUTION: EMC conformance

Always check the installation before going to sea to make sure that it

is not affected by radio transmissions, engine starting etc.
