6. Operation
6.1. Power On/Off
- To Turn On: Push the MODE button for 1 second. The LCD will display wind speed, temperature, and a battery icon. The backlight will activate for 5 seconds.
- To Turn Off: Push the SET button to turn off the unit.
6.2. Setting Wind Measurement Units
- Push the MODE button for 3 seconds until the "m/s" symbol starts to blink.
- Push the SET button to cycle through the available measurement units: m/s (meters per second), km/h (kilometers per hour), ft/min (feet per minute), knots (nautical miles per hour), mph (miles per hour).
- Push the MODE button again to confirm the desired measurement unit.

6.3. Measurement Modes
The device supports three measurement modes:
- Cu (Current Wind Speed): Displays the real-time wind speed.
- MAX (Maximum Wind Speed): Shows the highest wind speed recorded during the measurement session.
- AVG (Average Wind Speed): Calculates and displays the average wind speed over the measurement session.

6.4. Temperature Unit Switch (°C/°F)
Press the °C/°F button to switch between Celsius and Fahrenheit temperature units.
6.5. LCD Backlight
Pressing any key will activate the LCD backlight for 5 seconds, improving readability in low-light conditions.
6.6. Wind Chill Indication
When the ambient temperature drops below 0°C (32°F), a wind chill symbol will appear on the LCD, indicating the perceived temperature due to wind.
6.7. Measurement
Once powered on and configured, simply hold the anemometer in the airflow. As the wind vane (impeller) turns, the LCD will instantly display the wind speed and temperature according to the selected mode and units.

7. User Tips
- For accurate readings, ensure the anemometer's impeller is directly facing the airflow.
- When measuring in fluctuating wind conditions, use the MAX or AVG modes to get a better understanding of the wind profile.
- Always check the battery level before critical measurements.
8. Maintenance
- Clean the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Keep the impeller free from dust and debris to ensure accurate measurements.
- Remove the battery if the device will not be used for an extended period to prevent leakage.
- Store the device in a cool, dry place, away from direct sunlight.
9. Troubleshooting
- Device does not turn on: Check battery installation and ensure the battery has sufficient charge.
- Inaccurate readings: Ensure the impeller is clean and unobstructed. Verify the correct measurement unit is selected.
- LCD display is dim: Replace the battery.
