The ADC measures ambient temperature,
wind speed, and it also tells compass
directions.
One of the propeller blades is red-colored to
indicate the magnetic north pole.
Four reference points were engraved on the
ADC as reference points.
To check bearing of an object, make sure
that the propeller cover is opened, and the
blades are entirely exposed to air.
Tilt the ADC until the propeller blades are
parallel to the horizon, and the propeller
blades rotate freely.
The red-colored blade of the propeller will
points to the magnetic north pole. Make use
of the reference points (marked on the
product) to check the direction of the target
object.
