- WCL-°F (Wind chill in Fahrenheit)
- WCL (Wind Chill): A physical quantity characterizing the relationship between wind speed and cooling.
- DP (Dew Point): The temperature at which air becomes saturated with moisture (the temperature at which fog will form).
5.7. MAX/MIN/AVG Function
- Press the AVG (⑥) button repeatedly to select "MAX" (maximum), "AVG" (average), or "MIN" (minimum) wind speed values.
5.8. Backlight
- To turn on the backlight, press and hold the Backlight (sun icon) button for over 3 seconds.

- The backlight will also turn off automatically within 15 seconds if not manually turned off.
6. Maintenance
6.1. General Care
- Keep the device clean and dry. Wipe with a soft, damp cloth if necessary. Do not use abrasive cleaners or solvents.
- Avoid exposing the device to extreme temperatures, humidity, or direct sunlight for prolonged periods.
- Protect the fan blades from dust and debris to ensure accurate readings.
6.2. Battery Replacement
When the low battery indicator appears on the LCD, replace the batteries promptly to ensure continuous and accurate operation. Refer to section 4.1 for battery installation instructions.

9. User Tips
- For the most accurate wind speed readings, ensure the anemometer's fan is directly facing the wind source.
- When measuring temperature, allow a few moments for the NTC thermometer to stabilize and provide a precise reading.
- Remember that altitude readings are derived from atmospheric pressure and can fluctuate with weather changes. For critical applications, cross-reference with other reliable altitude sources.
- The device has a stated accuracy of ±5% for wind speed measurements.
