3. Setup and First Use
- Charging the Device: Before first use, fully charge the Temtop C10 monitor using the provided USB charging cable. Connect the cable to the micro USB charging port on the device and a standard USB power adapter (not included). The battery indicator on the display will show charging status.
- Power On/Off: Press and hold the single button on the device to power it on or off.
- Initial Readings: Allow the device a few minutes after powering on to stabilize its readings. The monitor will immediately begin displaying current CO2, temperature, and humidity levels.
- Unit Switching: Briefly press the single button to switch between Celsius (°C) and Fahrenheit (°F) for temperature display.
4. Operating the Monitor
Understanding the Display:
The large digital display provides clear, real-time readings for all three parameters:
- CO2 Concentration: Displayed in Parts Per Million (PPM).
- Temperature: Displayed in Celsius or Fahrenheit.
- Humidity: Displayed as a percentage (%).

CO2 Level Indicator:
The monitor features a 3-color LED indicator to provide quick visual feedback on CO2 levels:
- Green: 0 – 700 PPM (Good air quality)
- Yellow: 701 – 2500 PPM (Fair air quality, consider ventilation)
- Red: ≥ 2501 PPM (Poor air quality, immediate ventilation recommended)

Smart Connectivity (if applicable):
Some Temtop models offer smart connectivity. If your C10 model supports it, you can connect it to a mobile application to track air quality data in real-time and monitor your family's respiratory health. Refer to the specific app instructions for pairing and usage.

5. Calibration
The Temtop C10 offers two calibration modes to ensure accurate CO2 readings:
Automatic Calibration Mode (ABC OFFSET algorithm):
The device is equipped with an ABC OFFSET algorithm that regularly detects and corrects the surrounding CO2 value. This feature helps maintain accuracy over time by dynamically adjusting readings based on the lowest CO2 concentration detected over a period (typically 8 days), assuming that the lowest concentration represents fresh outdoor air (approximately 400 ppm CO2).
Manual Calibration Mode:
For precise calibration, especially after prolonged use in a stable environment or if you suspect inaccurate readings, manual calibration is recommended. To perform manual calibration, expose the device to fresh outdoor air (approximately 400 ppm of CO2) at least 1 meter away from people for a specified period (refer to the device's on-screen instructions or full manual for exact duration and steps).

6. Maintenance
To ensure the longevity and optimal performance of your Temtop C10 monitor, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners, solvents, or harsh chemicals.
- Storage: Store the monitor in a cool, dry place away from direct sunlight and extreme temperatures. Use the provided storage box when not in use for extended periods.
- Avoid Obstruction: Ensure the sensor vents (typically on the back or sides) are not blocked, as this can affect reading accuracy.
- Battery Care: Recharge the battery regularly, even if the device is not in constant use, to maintain battery health. Avoid completely draining the battery frequently.
7. Troubleshooting
If you encounter issues with your Temtop C10 monitor, try the following troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is garbled or unreadable. | Software glitch, low battery, or internal component issue. | 1. Fully charge the device. 2. Power off and restart the device. 3. If the issue persists, contact customer support. |
| Inaccurate CO2 readings. | Sensor obstruction, need for manual calibration, or environmental factors. | 1. Ensure sensor vents are clear. 2. Perform a manual calibration in fresh outdoor air. 3. Avoid placing the device near strong air currents or heat sources. |
| Short battery life. | Battery degradation over time, frequent use, or background processes. | 1. Ensure the device is fully charged before use. 2. Keep the device plugged in for continuous monitoring if possible. 3. Battery life is approximately 48 hours depending on usage. |
| Device does not power on. | Completely drained battery or power issue. | 1. Connect to charger and allow several minutes for charging before attempting to power on. 2. Try a different USB cable or power adapter. |
