10.0 Wind Speed Mode - Before Using the Wind Speed Mode

How Wind Speed is Measured

Before and After Measuring a Wind Speed

To Measure Wind Speed

The ADC is equipped with a propeller that is

similar to a traditional aerovane.

When the propeller faces the wind, it

rotates and generates signal. This product

will pick up the signal and converts it into

wind speed.

Turn the ball-shape propeller by your thumb

and index finger until the propeller blades

are entirely exposed, and it is not sheltered

by the case.

Select Wind Speed Mode. Point the blades

directly towards the wind direction, and

make sure that the blades rotate freely.

When the wind passes through the propeller,

the blades rotate. The ADC starts to

measure, and shows the current, average

and maximum wind-speed readings.

! After a wind speed measurement, rotate the

propeller to a closed position to prevent dirt

from getting into it.
