Notes
(1) Hydra Pilots, Hercules Pilots, HS Pilots and Halcyon FFDs will
also require the Heading Node to be set to your desired choice.
Refer to the relevant user manual for further information.
(2) 20/20 displays will require Heading to be re-selected. Simply
re-select this function and refer to
section 5.6.5 for more
information.
3.4.3 Super Halcyon 3 Compass Calibration Procedure
(1) Check for any magnetic devices placed near the
compass, especially ones that are out of their normal
places.
(2) On a calm day select a stretch of open water with
little traffic, (so you will not have to take avoiding action
that would ruin the calibration). The flatter the water and
the less the wind the easier it will be to meet the
conditions for the calibration.
(3) Check for any large steel structures nearby that may
cause additional erratic deviations.
(4) At a speed of about three knots slowly motor the
boat through a full one and a half turns (540°), taking six
to fifteen minutes to complete the one and a half turns. At
this rate the heading should be changing at no faster than
one degree every second. Having a watch beside the
compass display should considerably assist the
helmsman in monitoring the rate of turn. The rate of turn is
indicated on the Halcyon Display.
(5) When the compass has completed its calibration, the
displayed heading will rotate in the opposite direction for
360° and settle on the correct bearing to indicate the
calibration is complete. You should continue to turn until
you see this.
Note
If the displayed heading does not reverse, the calibration was
discarded because the conditions were not met. You must start
again, or try another day when wind and wave conditions are
calmer.
