HB-3001-02 32
The rate of change of heading must not fall below 0.2 of a degree per
second during the 360° turn, i.e. the turn must not take longer than 12
minutes.
The rate of change in heading is reasonably constant.
The compass is installed in a location a safe distance from magnetic
interference such as iron keels, engines, loudspeakers etc.
Consideration should also be given to electrical cables which may carry
high currents (e.g. large motors).
The compass is installed in a location as close to the centreline of the boat
as possible. Avoid areas such as the fore peak and the sides of the hull
where the effects of pitch and roll are at their greatest.
On steel hulled vessels, the compass will need to be installed above decks
away from the effects of the hull.
HALCYON 2000 COMPASS CALIBRATION
PROCEDURE(Auto Swing)
Check for any magnetic devices placed near the compass, especially ones
that are out of their normal places.
On a calm day select a stretch of open water with little traffic (so you will
not have to take avoiding action which would affect the calibration). The
flatter the water and the less the wind the easier it will be to meet the
conditions for calibration.
Check for and avoid sailing close to any large steel structures nearby, that
may cause additional, erratic deviations.
Now select:-

The display will now show the degrees of turn completed so far. When the
full 360 deg turn has completed within the limits described earlier, the
display should say “PASS” to indicate a successful swing.
