5. Mode d'emploi
5.1 Lecture de l'écran LCD
The EL-USB-2-LCD features a clear LCD display that shows the current temperature and humidity readings. The display cycles between temperature (°C or °F) and relative humidity (%RH) at regular intervals. Alarm indicators (if configured) may also appear on the display.
5.2 Enregistrement des données
Once configured and started, the logger will automatically record data at the specified sampling rate. The LED indicators will provide visual feedback on the logger's status (e.g., green for normal operation, red for alarms).
5.3 Téléchargement des données
