Calibrating the MSC 10

Calibration of the MSC-10 is done in a similar fashion to other NMEA 2000 heading sensors (GPS 24xd, 9-axis Compass, etc.), accessed via the MFD Communications Menu:

1. Select Settings > Communications > NMEA 2000 Setup > Device List

2. Select the MSC 10 from the device list

3. Select Review > Compass Cal. > Begin

4. Follow the on-screen instructions until the compass calibration is complete

MSC 10 Basic Calibration

When performing basic calibration, first calibrate the compass and then align the heading in one continuous procedure. 

Note: The boat must be able to reach a cruising speed of at least 6.4 km/h (4 mph) to perform the heading alignment. 

1. Drive the boat to a location with calm, open water

2. Set the display to view heading data from the connected compass 

   • NOTE: Do not use GPS Course Over Ground (COG) to perform basic calibration

3. Disconnect the compass from the NMEA 2000 network or turn off the power to the NMEA 2000 network

4. Wait while the boat becomes level and stationary

5. Turn on power to the compass and wait until the heading data appears on the display

   • NOTE: If this is the first basic calibration after a factory reset, the heading is blank

6. Within three minutes, complete two full slow, tight circles taking care to keep the boat as steady and level as possible; the boat should not list during calibration

7. Continue turning in the same direction at the same speed for approximately one and a half rotations until the heading data appears. When the heading data appears, the compass has been calibrated successfully and you can align the heading (optional)

8. Select an option:

   • To align the heading to match the front pf the boat, proceed to the next step

   • If choosing to not align the heading, stop turning and wait, keeping the boat stationary. Over the next two minutes the heading data should disappear and then reappear. When the heading data reappears, the compass should be calibrated and no heading offset should be applied

     • NOTE: If an unwanted heading offset is applied, repeat the calibration procedure

9. Continue turning in the same direction at the same speed for approximately ten seconds, until the heading data disappears from the display

10. When it is safe, straighten the boat and drive in a straight line at cruising speed (must be at least 6.4 km/h (4 mph)) until the heading data appears; when the heading appears, the compass has been calibrated, and the heading has been aligned

11. Test the results of the calibration, and repeat this procedure if necessary
