Sensors Control Panel
The Sensors control panel lets you see the compass and
accelerometer working, set the magnetic declination
angle, and calibrate the sensors. Select Start > Settings >
System > Sensors.
The Magnetic Declination angle is the difference
„
between True North and magnetic North. Applications
that are using True North use this value to adjust the
readings from the compass.
To calibrate the compass, select Calibrate Compass.
„
Rotate the handheld around all three axis several times in
every orientation possible (for at least 10 seconds). Press
Stop when you are done. Calibrating the compass is
very important and needs to be done often. Changes in
environment, added attachments to the handheld, and
mounting options can affect the sensor readings. If you
are mounting the handheld to a pole, mount it first and
then calibrate the compass.
