4.3 Alarm Function
The device features an audible and visual alarm that activates when CO2 levels exceed a user-defined threshold. This allows for immediate action to improve air quality.
- Refer to the full operation manual for detailed instructions on setting alarm thresholds.
5. Maintenance
5.1 Calibration
The CO2 detector is equipped with a stable NDIR sensor and can be calibrated for optimal accuracy.
Image: The CO2 detector's screen displaying "CAL" and a CO2 reading of 400 ppm, indicating it is in calibration mode. This image highlights the ease of manual calibration.
- To initiate calibration, press the CAL button. Follow the on-screen prompts.
- For best results, perform calibration in a well-ventilated outdoor area with known ambient CO2 levels (typically around 400 ppm).
5.2 Cleaning and Storage
- Clean the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Store the device in its hard carrying case when not in use to protect it from dust and physical damage.
- Remove batteries if storing for extended periods to prevent leakage.
