ST60 Compass Instrument Owner’s Handbook
The Fluxgate Compass transducer must also be sited:
• At least 0.8 m (2 ft 6 in) away from the vessel's steering compass to avoid
deviation in both compasses.
• On a bulkhead below deck.
Note:
On steel vessels the Fluxgate Compass transducer can be mounted above deck.
When mounted above deck, performance may be impaired due to increased motion.
• To allow reasonable access for installation and servicing.
• Away from any equipment or other installation which may shield the trans-
ducer or otherwise disturb the earth’s magnetic field, e.g. large ferrous or
magnetic items, communications equipment or cabling.
• On a vertical mounting surface. Where necessary, make up a suitable non-fer-
rous wedged packing piece to provide the necessary vertical surface.
There must also be a viable route for the transducer cable to be routed to the
instrument.
Instrument
CAUTION:
The presence of moisture at the rear of the instrument could cause
damage either by entering the instrument through the breathing
hole or by coming into contact with the electrical connectors.
ST60 instruments can be fitted either above or below deck, provided the rear of
the instrument is sited where it is protected from contact with water.
Each instrument must also be positioned where it is:
• Easily read by the helmsman.
• Protected against physical damage.
• At least 9 in (230 mm) from a compass.
• At least 20 in (500 mm) from radio receiving equipment.
• Reasonably accessible from the rear for installation and servicing.
