6. Operating Instructions

6.1. Power On/Off

Power On: Briefly press the "MODE" button to turn on the device. The LCD display will illuminate.
Power Off: Long press the "SET" button to turn off the device. The anemometer also features an auto power-off function after 14 minutes of inactivity to save battery.

6.2. Selecting Measurement Units

After powering on, you can change the wind speed measurement unit:

Long press the "MODE" button until the current unit (e.g., "m/s") starts to blink.
Briefly press the "MODE" button repeatedly to cycle through the available units: m/s, km/h, ft/min, mph, knots.
Press the "SET" button to confirm your desired unit.

6.3. Switching Temperature Units (°C/°F)

To switch between Celsius and Fahrenheit:

Briefly press the "°C/°F" button located on the device. The display will instantly switch between the two temperature scales.

6.4. Measurement Modes (MAX/AVG/Current)

The anemometer can display current, maximum, and average wind speeds:

Briefly press the "SET" button to cycle through the measurement modes: Current, MAX (maximum wind speed recorded since power-on), and AVG (average wind speed recorded since power-on).

6.5. Backlight Display

The LCD screen has a backlight for improved visibility in low-light conditions. The backlight activates automatically when any button is pressed and will turn off after a short period of inactivity to conserve battery.
