Operating Instructions
Power On/Off
- To power on, press the MODE/O button.
- The device features an auto power-off function to conserve battery life.
Measuring Wind Speed
Hold the anemometer so that the fan (impeller) faces directly into the wind. The wind speed will be displayed on the LCD screen.

Changing Measurement Units
Press the MODE/O button repeatedly to cycle through different measurement units for wind speed (m/s, km/h, mph) and temperature (°C, °F).
Beaufort Wind Scale
The device displays wind speed using a Beaufort wind scale bar graph, providing a visual indication of wind intensity.
Wind Chill Display
The anemometer can also display the calculated wind chill factor, which indicates how cold it feels due to the combined effect of temperature and wind speed.
Data Hold Function
To temporarily freeze the current reading on the display, activate the data-hold function. Refer to the device's specific button layout for the hold button (often indicated by a 'HOLD' or similar icon).
LCD Backlight
Press the backlight button (if available, often combined with another function or a dedicated light icon) to illuminate the LCD screen for better visibility in low-light conditions.

Maintenance
Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the impeller (fan) is free from dust and debris for accurate readings.
Battery Replacement
When the battery indicator appears on the LCD, replace the CR2 battery as described in the "Battery Installation" section. Remove the battery if the device will not be used for an extended period to prevent leakage.
Storage
Store the anemometer in a cool, dry place, away from direct sunlight and extreme temperatures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Dead or incorrectly installed battery. | Check battery polarity or replace with a new CR2 battery. |
| Inaccurate wind speed readings. | Impeller obstructed or damaged; device not facing wind correctly. | Ensure impeller is clean and rotates freely. Point the device directly into the wind. |
| Display is dim or flickering. | Low battery. | Replace the CR2 battery. |
