If the data differs by more than 3° the new reading will not be used. In this
case the color turns to red (flashing). Please repower the sensor and re-do the
calibration.
An unsuccessful calibration can be caused by:
- Bad weather conditions (too high waves and/or strong wind)
- Not the right speed or circle distance performed
- Moving magnetic components close to the sensor
- Electronic equipment close to the sensor
- Inproper positioning of the sensor
Note: Red flashing can also be caused by a different internal failure of the
NavSensor. Please refe
r to chapter “Diagnostic Indication”
Note: After the first successful installation and calibration general aligment
of the Navsensor in respect to the fore and aft line of the boat should be
checked. This is done by performing several plottings to different landmarks
(please take magnetic variation into account as well). If there is a deviation in
the alignment the sensor should be turned on its bracket accordingly (if so, an
additional sensor calibration has to be performed afterwards).
