After you calibrated the compass and mounted your MAX, we advise you to follow the steps below to ensure accurate data.
A. SET COMPASS MOUNT OFFSET
Is your MAX mounted at an angle compared to the bow? Your MAX needs some correction. If not needed, go to step B.
1. Measure or estimate the angular difference between bow (forward direction) and MAX. Keep in mind: mounting at the right angle on the port is -90°. Mounting at the right angle on the starboard is +90°. Anything in between will work. Rear-facing MAX is possible with +180°.
2. Go to Menu > System > Sensors > Set Compass Offset.
– MINUS OR PLUS DEGREE: hold the left button for two seconds
– CHOOSE POSITION: press top middle button (NEXT)
– MINUS: press left button
– PLUS: press right button
3. Press Save. MAX is now configured for this mounting position and will remember it. Attitude outputs (Heel, Pitch, Compass) will be referenced to the boat and not to MAX. These numbers might not make sense when MAX is not mounted.
B ZERO HEEL AND PITCH
Go to Menu > System > Sensors > Zero Heel and Pitch. Press the top right button to zero Heel and Pitch. The status of your calibration can be found below the screen.
