Chapter 4: Calibration 27
Heading alignment
Carry out heading alignment as follows:
1. Align the vessel with a known bearing; preferably a transit bearing.
2. Use the
< and > buttons to adjust the value on the ST60+ Compass instru-
ment digital display until it corresponds to the known bearing.
Locked mode data
The locked mode data screen enables you to select which heading is selected as
the normal operating display in locked mode. This can be either:
• The locked or ‘fixed’ heading.
or
• The live or ‘current’ heading.
Use the
< and > buttons as necessary, to select the required heading. Select:
• F for Fixed heading.
• C for Current heading.
Variation setting
A positive value indicates easterly and a negative value westerly. If the variation
has not been set, or the data is not available, the digital display shows a series of
dashes.
Changes to variation must be accepted before a TRUE heading can be selected,
(see
True/magnetic selection
below).
If the ST60+ Compass instrument is connected to SeaTalk and a value for
variation is present on SeaTalk (e.g. from an autopilot), this is accepted as the
value for the instrument. If a value is not present on SeaTalk, or if the instrument is
not connected to SeaTalk, use the
< and > buttons to set the appropriate value.
True/magnetic selection
Use this option to select either MAG (netic) or TRUE as the heading display
default (indicated by the black square adjacent to either MAG or TRUE , as
appropriate).
If theST60+ Compass instrument is used in a system without a SeaTalk
compatible Autopilot, or it is being used independently, set the digital display to
MAG .
True headings cannot be displayed if variation data is not available.
