4. Fonctionnement
4.1 Affichage terminéview
The large color display provides a comprehensive view of current air quality parameters:
- CO2 Concentration (PPM): Central large number, indicating parts per million.
- Température: Displayed in Fahrenheit or Celsius.
- Humidité: Affiché en pourcentagetage.
- Temps: Heure actuelle.
- Statut d'alarme : Icônes indiquant les alarmes actives.
- Indicateur de batterie : Affiche la durée de vie restante de la batterie.
4.2 Understanding CO2 Levels
The device categorizes CO2 concentration into three stages, indicated by color changes on the display and corresponding icons:
- Normale Stage: CO2 ≤ 800 ppm (Green indicator). Indicates good air quality.
- Avertissement Stage: CO2 801 - 1600 ppm (Yellow indicator). Suggests ventilation may be required.
- Dangereux Stage: CO2 > 1600 ppm (Red indicator). Indicates poor air quality; immediate ventilation is recommended.
4.3 Réglage des alarmes
The LFF CO2 Detector features customizable dual alarms. When the measured CO2 level reaches your set high or low alarm threshold, an audible beep will sound, and the alarm icon will flash. Refer to the device's on-screen menu or specific buttons (usually labeled 'SET' or 'MODE') to adjust the CO2 alarm values.
4.4 Réglage du rétroéclairage
The device offers three levels of backlight brightness (100%, 50%, 0%) to suit different lighting conditions and conserve battery life. Use the designated button (often indicated by a light bulb icon) to cycle through the brightness settings.
4.5 Réglage de l'heure et de la date
To set the current time and date, navigate through the device's menu using the control buttons. Follow the on-screen prompts to adjust hours, minutes, and date. Consult the quick start guide or on-screen instructions for specific button sequences.
5. Entretien
5.1 Nettoyage
Pour nettoyer l'appareil, essuyez délicatement l'extérieur avec un chiffon doux et sec. N'utilisez pas de nettoyants abrasifs ni de solvants et n'immergez pas l'appareil dans l'eau. Assurez-vous que les orifices de ventilation du capteur sont exempts de poussière et de débris.
5.2 Entretien de la batterie
To maximize battery lifespan, avoid fully discharging the device frequently. For prolonged storage, charge the battery to approximately 50% and store in a cool, dry place. If using the device continuously, it is recommended to keep it plugged in to a power source.
6. Dépannage
- Mesures de CO2 inexactes : If you suspect inaccurate readings, take the device outdoors for 10-15 minutes to allow it to recalibrate to ambient CO2 levels (typically around 400-450 ppm). Ensure the sensor vents are not obstructed.
- Durée de vie de la batterie courte : Ensure the device is fully charged before use. Adjust the backlight brightness to a lower setting to conserve power. For continuous monitoring, keep the device connected to a power source via the Type-C cable.
- L'appareil ne s'allume pas : Check if the battery is charged. Connect the device to a power source and attempt to power it on again. If the issue persists, contact customer support.
- L'alarme ne sonne pas : Verify that the alarm thresholds are set correctly and that the alarm function is enabled in the device settings.
