3.1 General
The instrument head is fully waterproof and can, therefore, be installed on
deck or below. The connections should be protected from water penetration
and should, if possible, allow rear access to remove the desiccant pack, if
required. The position selected should, in the first instance, meet the
requirements of the helmsman, or crew.
The selected surface for the instrument must be flat and even to within 0.5mm.
Before installation, note the Serial Number and keep it in a safe place.
Great care should be taken when deciding on the location for the heading
sensor; it should be mounted away from areas of magnetic interference, and as
close the vessel’s centre of pitch and roll, as possible. The mounting should
also be solid and free of vibration. On steel vessels, the sensor should be
mounted on the mast, approximately one to three metres from the main
structure; although in other cases, do not install the sensor at the flybridge or
the mast as the display reading will swing as the boat rolls.
As a guide to minimising magnetic interference, the sensor should be a
minimum of:
ONE
metre from:
Radios and loud-speakers
RDF Instruments
Other compasses
Cables carrying more than 1/2 Amp
