If you are not sure of the magnetic suitability of the chosen location, carry out a survey of the site as follows:

1.Temporarily fix a simple hand bearing compass at the intended location.

2.Swing the vessel through 360° while at the same time observing differences between the hand bearing compass and the vessel's main steering compass.

3.If there are no differences, greater than 10° on any heading, then the site is suitable for the Fluxgate Compass transducer.

Using the self-tapping screws provided, mount the Fluxgate Compass transducer vertically on a suitable bulkhead, so that the connecting cable is downmost.

Running transducer cable

Observing the following guidelines, run the transducer cable to the instrument:

•If the cable has to be fed through the deck, always use a good quality deck gland.

•Where cables are fed through holes, always use grommets to prevent chafing.

•Secure long cable runs so they do not present a hazard.

•Wherever possible, route the cable away from fluorescent lights, engines, radio transmitting equipment, as these may cause interference.
