1 Current reading:
The current heading reported by the AR200.
2 Maximum deviation at last calibration:
The maximum deviation reported during the last linearization process.
Important:
• If the Maximum deviation at last calibration is 45° or above, it is recommended
that the AR200 unit is moved and re-installed in a location which is subject to
less magnetic interference.
Calibration in progress:
While linearization is in progress the progress percentage is displayed.
3 Compass offset
Once the linearization process has completed, it is possible that the heading value
may be slightly out of alignment. This is common where installation space is limited
and the AR200 is not properly aligned with your vessel’s longitudinal axis. In this
case, it is possible to manually adjust the Compass offset.
4 Compass lock
When enabled, the Compass lock prevents the continual monitoring and adaptation
of the compass linearization process. For more information, refer to:
Compass lock .
5 Reset calibration
You can reset your AR200’s current linearization settings by selecting Reset
calibration
Continual monitoring and adaptation
To ensure optimum performance, after the initial linearization process is complete the unit continues
to monitor and adapt the compass linearization to suit current conditions.
If the conditions for linearization are less than ideal, the automatic linearization process temporarily
pauses until conditions improve again. The following conditions can cause the linearization process
to temporarily pause:
• significant magnetic interference is present
• vessel speed too slow or too fast
