5. Setup Guide
Follow these steps to set up your Orium Quaelis 16 CO2 Sensor:
- Unpack: Carefully remove the CO2 sensor and its accessories from the packaging.
- Placement: Place the sensor on a stable, flat surface in the area where you wish to monitor air quality. Ensure it is not obstructed and has good air circulation. Avoid placing it directly next to windows, doors, or ventilation outlets that could affect readings.
- Power Connection: Connect the provided power cable to the sensor and plug it into a 230V power outlet. The device will automatically power on.
- Initial Stabilization: Allow the device approximately 5-10 minutes to stabilize and begin displaying accurate readings after initial power-on.

Position the CO2 sensor in the desired monitoring area, ensuring it is on a flat, stable surface away from direct airflow sources like vents or open windows for accurate readings.
6. Operating Instructions
6.1 Display Interpretation
The sensor's display provides real-time information on CO2 concentration, temperature, and relative humidity. The CO2 reading is indicated in parts per million (PPM) and changes color to visually represent air quality levels:
Figure 3: Green CO2 reading (e.g., 465 ppm) indicates good air quality.
Figure 4: Orange CO2 reading (e.g., 965 ppm) indicates elevated levels, suggesting ventilation is needed.
Figure 5: Red CO2 reading (e.g., 1265 ppm) signifies high CO2 concentration, requiring immediate action to improve ventilation.
The display also shows temperature in degrees Celsius (°C) and relative humidity (%RH).
6.2 Alarm Customization
The visual and audible alarms are fully customizable. You can set specific CO2 thresholds at which the alarms will activate. Refer to the device's physical buttons or on-screen menu (if applicable) for specific adjustment procedures. When an alarm triggers, it provides a clear indication that ventilation is required.
6.3 Manual Calibration
The Quaelis 16 supports manual calibration to maintain long-term accuracy. To perform a manual calibration, place the device in an area with fresh outdoor air (approximately 400 ppm CO2) and follow the calibration instructions provided in the device's menu or user interface. This process helps reset the sensor's baseline for optimal performance.
6.4 Data Logging and PC Connection
The device can store up to 12,700 measurement records. To access and save this data:
- Connect the Orium Quaelis 16 to a Windows PC using a compatible USB cable (not explicitly mentioned if included, but implied for PC connection).
- Download and install any necessary software or drivers from the official Orium website.
- Follow the software instructions to transfer, view, and analyze the recorded data.
7. Maintenance
- Cleaning: Gently wipe the exterior of the device with a soft, dry cloth. Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the sensor or display.
- Battery Care: The integrated 2000 mAh Lithium battery is rechargeable. To prolong battery life, avoid fully discharging it frequently and store the device in a cool, dry place if not used for extended periods. Recharge using the provided power cable.
- Storage: When not in use, store the sensor in a clean, dry environment within its operating temperature range.
8. Troubleshooting
- Q: The device is not turning on.
- A: Ensure the power cable is securely connected to both the device and a functional 230V power outlet. If operating on battery, check if the battery is charged. Connect to power for a few minutes to see if it powers on.
- Q: CO2 readings appear inaccurate or fluctuate excessively.
- A: Perform a manual calibration in fresh outdoor air. Ensure the sensor is not placed near strong air currents, open windows, or direct sources of CO2 (e.g., exhaled breath, burning candles). Allow sufficient time for stabilization after moving the device.
- Q: Alarms are not activating or are too quiet.
- A: Check the alarm settings in the device's menu to verify that the thresholds are set correctly and that the audible alarm is not muted or set to a very low volume. Ensure the visual alarm is not obstructed.
- Q: Cannot connect to PC or transfer data.
- A: Ensure the USB cable is properly connected. Verify that the necessary drivers and software for Windows PC are installed. Try a different USB port or cable. Consult the Orium website for software updates or troubleshooting guides.
