Example:
After auto-compensation, a comparison of a couple of Sailcomp 103AC
headings with "runs" from a chart indicate that the Sailcomp is reading 2° lower than it
should be. For instance, instead of displaying 180° it is displaying 178°. This means
that the sensor is pointing to the left of the boat's centerline by 2°. To correct this, enter
into the "Compensation Display" by simultaneously pushing the
timer
and
crs
(course)
buttons
until "
CAL
" appears. Now enter the "Alignment Offset" section of the software
by pushing and releasing the
crs
(course)
button
. Apply a short push to the
nav button
to examine the value entered for "A" Offset (from the factory, this will be "00"). You
need to add 2° to all headings to adjust for the "A" error, so push and hold down the
nav button
until "
02
" appears on the display and then release the button. Exit by push-
ing the
crs
(course)
button
again. Now, when you point to your reference of 180°, the
Sailcomp will display 180°.
Very Important! Once the Alignment Error is adjusted, it is stored in memory and
never has to be re-adjusted unless the sensor is moved.
Disabling/Enabling Auto-Compensation
With auto-compensation disabled, your compass will be using the last compensation
that has been stored, but will be unable to update itself if something changes in the
boat's magnetic environment, etc. In essence, it is locked.
If you want to disable or enable auto-compensation, enter into the "Compensation
Display" by simultaneously pressing the
timer
and
crs
(course)
buttons
until "
CAL
"
appears. Release the buttons and "
on
" appears followed by
3 digits
(###). Hold down
the
port button
and the display will toggle between "
oFF
" and "
on
". Release the but-
ton while "oFF" is displayed to disable auto-compensation.
Important Note:
Be sure that
Damping Knob is in Position 1
while disabling or
enabling auto-compensation.
Auto-compensation may be turned on/off in the Sailcomp 103AC whenever desired.
Just be aware of what state it is in. You may check this at any time by entering into the
"Compensation Display" and watching whether "
on
" or "
oFF
" is displayed.
To
exit
the "Compensation Display", apply two short pushes to the
crs
(course)
button
. Whatever was flashing on the display - "
on
" or "
oFF
" - will be activated and
the display will return to compass mode.
