7. Operating Instructions
7.1 Power On/Off
- Press the Switch button (power symbol) to turn the anemometer ON.
- Press and hold the Switch button again to turn the anemometer OFF.
- The device will automatically shut down after 14 minutes of no operation to conserve battery life.
7.2 Wind Speed Measurement
Once powered on, the device will immediately begin measuring wind speed. Ensure the impeller is exposed to the airflow you wish to measure.
- The probe can be rotated 180 degrees to position the impeller correctly relative to the wind direction.
- The current wind speed will be displayed on the main screen.
7.3 Unit Selection
- Press the Unit button to cycle through the available wind speed units: m/s, Ft/min, Knots, km/h, Mph.
- The selected unit will be displayed next to the wind speed reading.
7.4 Temperature Measurement and Unit Conversion
- The ambient temperature will be displayed below the wind speed reading.
- Press the °C/°F button to toggle between Celsius (°C) and Fahrenheit (°F) temperature units.
7.5 Measurement Modes (Max/Min/Average/Current)
- Press the Mode button to cycle through different measurement modes.
- Available modes typically include:
- Current: Displays the real-time wind speed.
- MAX: Displays the maximum wind speed recorded since the device was powered on or reset.
- MIN: Displays the minimum wind speed recorded since the device was powered on or reset.
- AVG (Average): Displays the average wind speed over a period.
- Refer to the display indicators to identify the active mode.

- Keep the impeller free from dust and debris to ensure accurate readings. Use a soft brush or compressed air if necessary, being careful not to damage the blades.
8.2 Battery Replacement
- When the low battery indicator appears on the display, replace all three AAA batteries promptly.
- Follow the battery installation steps in Section 6.1.
- Dispose of old batteries according to local regulations.
8.3 Storage
- If storing the device for an extended period, remove the batteries to prevent leakage.
- Store in a cool, dry place, away from direct sunlight and extreme temperatures.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Dead or incorrectly installed batteries | Check battery polarity; replace with fresh AAA batteries. |
| Inaccurate wind speed readings | Impeller obstructed or damaged; device not positioned correctly in airflow | Ensure impeller is clean and rotates freely. Position the anemometer directly into the airflow. |
| Display is dim or not visible | Backlight off; low battery | Activate backlight (hold °C/°F button for 2s). Replace batteries if low battery indicator is on. |
| Automatic shutdown occurs too quickly | Normal operation (14 minutes inactivity) | This is a power-saving feature. Press any button to reactivate. |
10. User Tips
- For the most accurate wind speed readings, ensure the anemometer's impeller is facing directly into the wind source.
- When measuring temperature, allow a few moments for the sensor to stabilize and reflect the ambient conditions accurately.
- Utilize the Max/Min modes to capture peak gusts or lowest wind speeds over a measurement period, which can be useful for various applications.
- The compact size makes it ideal for quick spot checks in hard-to-reach areas or for carrying in a toolkit.
