The SENSORO ALPHA/ALPHA+ must be calibrated for
accurate heading information. Calibration allows the unit to
separate the earth’s field from the magnetic fields generated
by your vehicle. Before beginning calibration, the SENSORO
ALPHA/ALPHA+ must be installed in your vehicle in the
location you wish to use it.
When to calibrate
• When the unit is used for the first time in a vehicle
• When the unit is mounted in a different location than
where previously calibrated
