IV. Operation Instruction
A. Measurement of Wind Velocity
1. Press the on/off button to turn on the anemometer.
2. Select the desired units by moving the unit selection
button.
3. Determine the approximate wind direction.
4. Hold the anemometer so that the air flow will pass
through the vane from the back to the front.
5. Wait for 4 seconds for a stabilized reading.
6. For mor accurate results, try to keep the axis of the
vane within 20° of the wind direction.
B. Measurement Temperature
1. Press the on/off button to turn on the anemometer.
2. Select the desired units by moving the unit °C/°F
selection button.
3. Let the wind pass through the vane (A thermocouple
is built into the center of the vane).
4. Read the temperature in the display.
C. Holding the Reading
Press the hold button to hold the reading of wind
velocity or temperature.
D. Finding the Max. / Min.
Press the max/min button, the max wind velocity or
Max./Min. temperature measured during the
measurement shall be displayed and updated on
LCD.
