Use the left and right arrow buttons to navigate and select items on the main menu. Press the 'Confirm' button (often labeled 'FUNC' or similar) to enter the selected display interface.
5.2 Fonctions de mesure
Once a measurement function is selected from the main menu, the device will display the corresponding readings. For example, selecting 'Temperature' will show the current temperature.
To switch units (e.g., from Celsius to Fahrenheit for temperature, or m/s to km/h for wind speed), press the 'UNIT/ESC' button. This button also serves to exit the current measurement screen and return to the main menu.
For specific measurements:
- Température et humidité : Ensure the sensors are exposed to the environment you wish to measure.
- Vitesse du vent: Position the device so the built-in fan is facing the wind direction.
- Éclairage: Point the light sensor towards the light source.
- Barometric Pressure & Altitude: These measurements are typically taken automatically by internal sensors.
