Wind calibration
Calibrate your wind transducer as follows:
• [Linearise transducer] — Turn your boat in circles until all sectors have
been calibrated (the ring turns green as sectors complete).
• [Align wind transducer] — Head your boat directly into observed wind
and select [Align] .
• [Angle adjustment] — You can apply a specified offset to wind angle
readings.
• [Speed adjustment] — You add a scaling factor to apparent wind speed.
Speed calibration
Calibrate your speed transducer as follows:.
For best results, ensure that there is minimal or no tide/current effect when
calibrating speed through water.
• [Set STW to SOG] — Select to apply a scaling factor to all STW readings,
based on the present difference between STW and SOG.
• [Adjust STW] — Apply a scaling factor to all speed through water values.
Multiple data sources (MDS)
MDS is a Raymarine scheme for managing multiple sources of identical data
types on the same network (e.g.: in an MFD network you may have more than
one source of GPS / GNSS position data).
The MFD will automatically select a preferred data source (device) to use
for that data type.
MDS can be used for the following data types:
• Depth
• Speed through water
• Heading
• GPS
• GPS Datum
• Wind
• Time & Date
If you do not want to use the automatically selected data source you can
manually select your preferred data source.
