5. Operation
5.1. Power On/Off
- Press the Power Switch Button (marked with a power symbol) to turn the anemometer ON.
- To turn OFF, press and hold the Power Switch Button for a few seconds. The device also features an automatic power-off function after a period of inactivity to save battery.
5.2. Wind Speed and Temperature Measurement
Once powered on, the device will immediately begin measuring wind speed and temperature. Ensure the wind speed sensor (rotating fan) is exposed to the airflow for accurate readings. The current wind speed and temperature will be displayed on the LCD.
5.3. Changing Wind Speed Units
- Press the Unit Button to cycle through the available wind speed units: meters per second (m/s), feet per minute (Ft/min), knots (Knots), kilometers per hour (km/hr), and miles per hour (Mph). The selected unit will be displayed on the LCD.
5.4. Changing Temperature Units and Backlight Control
- Press the C/F Button to switch the temperature display between Celsius (°C) and Fahrenheit (°F).
- Press and hold the C/F Button to turn the LCD backlight ON or OFF.
5.5. Mode Selection (Current, Average, Maximum Wind Speed) and Data Hold
- Press the Mode Button to cycle through the display modes for wind speed: Current, Average (AVG), and Maximum (MAX). The corresponding indicator will appear on the LCD.
- To activate the Data Hold function, press and hold the Mode Button. The "HOLD" symbol will appear, freezing the current readings on the display. Press and hold again to release.

7. Maintenance
7.1. Cleaning
To clean the device, use a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the casing or the display. Keep the wind speed sensor free from dust and debris for accurate readings.
7.2. Storage
When not in use for extended periods, remove the batteries to prevent leakage and damage to the device. Store the anemometer in a cool, dry place, away from direct sunlight and extreme temperatures.
7.3. Battery Replacement
When the low battery indicator appears on the display, replace all three AAA batteries promptly to ensure optimal performance.
8. Troubleshooting
- Device does not power on: Check if the batteries are installed correctly with the right polarity. Ensure the batteries are not depleted and replace them if necessary.
- Inaccurate readings: Ensure the wind speed sensor is clean and unobstructed. Make sure the device is held steadily in the airflow. Check for any physical damage to the sensor.
- Display is dim or flickering: This usually indicates low battery power. Replace the batteries.
9. User Tips
- For the most accurate wind speed readings, hold the anemometer vertically with the fan facing directly into the wind.
- Allow a few moments for the temperature sensor to stabilize when moving between environments with different temperatures.
- The backlight is useful in low-light conditions but consumes more battery power. Turn it off when not needed.
