5.4.9 Instantaneous Rate
While the Halcyon Display is showing the vessel’s mean rate of
turn, press the Scroll Down key, the DEG/S legend is shown to
indicate rate of turn displayed as degrees per second. The centre
analogue bar graph will now show the instantaneous rate of turn to
port or starboard.
Note
This is a useful feature when performing an automatic compass
swing on the Halcyon 2000 Compass, where it is necessary to
maintain a suitably slow and steady rate of turn. If the rate is kept
between 1 and 3 deg/s, a satisfactory calibration should be
achieved.
5.5 HALCYON 2000 COMPASS
The Halcyon 2000 Compass is a high performance electronic
transmitting compass which interfaces directly with your HS 2000
System. Heading and direction information may be selected for
display on any of the FFDs or on a Halcyon Display. In addition
analogue compass card type displays may be added if your
system has the optional Wind Board (402-10-005) PCB fitted.
Software incorporated within the Halcyon 2000 Compass allows
the unit to learn the magnetic fields in the vessel which may cause
deviation errors. These errors can be reduced to an insignificant
level by following the Calibration procedure described in Part 3.
