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.
(6) Eliminate any constant error in heading. These are
normally checked for by using shore-based transits, once
the error is known it can be eliminated by entering the
value into the HS 2000 under:
NAVIGATE ? HEADING, CALBRATE ? CAL VAL1
For example, the compass was reading 320 degrees and it should
read 316, then the value to enter would be -4.
3.3.4 Halcyon 2000 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
which would ruin the calibration). The flatter the water
and the less the wind the easier it will be to meet the
conditions for calibration.
(3) Check for any large steel structures nearby, that
may cause additional, erratic deviations.
(4) Scroll to the NAVIGATE menu and select COMP
CAL on the top half of the display. The display shows
OFF.
(5) Press Scroll Down until the lower text shows
CALBRATE flashing.
(6) Press the Enter key twice to display START and a
default setting of ‘0’.
