Electronic Compass (Elecom) - TMQ C-Drive 5 Installation And Service Manual

Compass Mounting Options
Calibration:
The compass unit will need to be
rotated for the correct heading to be
displayed. During sea trials further
adjustment may be required to
reduce any heading error displayed.
The compass is calibrated in the
factory. This will certainly be good
enough for sea trials and in most
cases will be as good or better than
the results of any auto calibration
on the vessel. Further calibration
should not be necessary unless
you find after seas trials that the
compass heading readings have
significant errors. If so, then follow the
calibration section.

Take care when handling the
compass - it is a sensitive piece of
equipment. The compass position
is the most important item in the
installation of the autopilot. Good
course holding is dependent on the
compass being free from magnetic
interference and excessive rolling or
pitching.
Position:
• Select a dry position free from
magnetic interference. (Note other
side of bulkhead for magnetic type
objects)
• Avoid positions near radios, aerial
cables, other current carrying
cables or speakers
• Mount the compass horizontally
with arrow (bow) facing in the same
direction as the vessel bow. Use
non magnetic screws (304 grade
stainless steel)
• R un cable to the C-drive amplifier
position (keep away from other
cables)
• Connect compass cable to the
NMEA socket of the C-Drive
