5.2 Wind Speed Measurement

1. Ensure the device is powered on.
2. Hold the anemometer so that the wind flows directly through the rotating vane sensor.
3. The current wind speed will be displayed on the LCD.
4. Press the Unit button to cycle through different wind speed units: meters per second (m/s), feet per minute (ft/min), knots, kilometers per hour (km/h), and miles per hour (mph).
5. Press the Mode button to switch between current wind speed, average wind speed, and maximum wind speed readings. The display will indicate the selected mode.

5.3 Temperature Measurement

• The device continuously measures ambient temperature, which is displayed on the lower part of the LCD screen.
• Press the °C/°F button to toggle the temperature display between Celsius (°C) and Fahrenheit (°F).

5.4 Data Hold Function

• To freeze the current reading on the display, press the H (Data Hold) button. The "HOLD" indicator will appear on the screen.
• Press the H button again to release the hold and resume live measurements.

5.5 Backlight Control

• To activate the LCD backlight for better visibility in low-light conditions, press the backlight button (often integrated with another button or a dedicated light icon).
• Press the button again to turn off the backlight.

5.6 Low Battery Indication
