3-16
The display will show the amount of turn completed so
far. Continue to turn the boat until the display shows
PASS or FAIL.
Notes
1. The compass calibration swing may be aborted at any time.
To do this, press the Enter key once. Next, using the Scroll
Down key change the value from ‘1’ to ‘0’, and then press Enter
to store. The display will now show OFF.
2.
The first time the system is switched on, or after a system
reset, the Heading will alternate with CAL. This is to indicate to the
user that the compass must be calibrated. This will disappear after
the compass has been calibrated.
(10) 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 Hydra 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.
3.5 HEEL ANGLE/LEEWAY CALIBRATION
Calibration of Heel Angle and Leeway is only necessary if a Heel
Angle Sensor is fitted to the yacht. The fitting of this sensor is
highly recommended because it allows the calculation of Leeway
and hence course corrected for Leeway which is used in the
calculation of Dead Reckoning.
3.5.1 Heel Angle Calibration
The Heel Angle Sensor should be mounted as upright as
possible, to read zero when the boat is upright. However any error
can be removed by means of Heel Angle Calibration.
The heel angle should be recorded by a visual check from astern,
on a calm day with the boat lying on slack warps in the dock, head
to wind, all the gear stowed in its normal place, and anyone
onboard standing on the centreline.
