3. Operation Safety

1. Please check the meter and accessories before use and beware of any damage or abnormal phenomenon. If the case is damaged, the LCD shows nothing, or the meter appears not to work properly, stop using it immediately.
2. Observe the operating instructions while measuring.
3. Do not open the meter or change internal wiring at will to avoid damages.
4. When the LCD displays the low battery symbol [?], replace the battery timely. Remove the battery if the meter is not used for a long time.
5. Do not store or use the meter in high temperature, high humidity, flammable, combustible, or strong electromagnetic environments.
6. Clean the case with a soft cloth and neutral detergent for maintenance. Do not use grinding agents or solvents to avoid case corrosion or damage.

Warning: Based on the principle of magnetic induction wind speed measurement, the product may be interfered with by strong electromagnetic radiation. Please stay away from such environments when using it.

6. Key Functions and Setup

The device features several function keys for operation:

1. ON/OFF: Short press to turn the device on or off.
2. UNIT: Short press to cycle through wind speed units (m/s, km/h, ft/min, knots, mph). Long press to switch between Celsius (°C) and Fahrenheit (°F) for temperature.
3. MAX/AVG: Press to select measurement mode: Maximum (MAX), Average (AVG), or normal value. When MAX is selected, the meter displays the highest reading recorded. When AVG is selected, it displays the average reading.
4. HOLD/BL:
   • HOLD: Short press to freeze the current measurement. Short press again to resume normal measurement.
   • BL (Backlight): Long press to turn the backlight on or off.
5. Automatic Shutdown: The device automatically powers off after 5 minutes of inactivity (default setting). To disable this feature, press and hold the "HOLD" key, then press the "ON/OFF" key. The LCD will display "APO OFF" to confirm.
