7. Troubleshooting
If you encounter issues with your CO2 monitor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or device does not power on. | No power supply or faulty USB cable. | Ensure the Micro-USB cable is securely connected to both the device and a working USB power source. Try a different USB port or power adapter. |
| Readings appear inaccurate or fluctuate significantly. | Improper placement, sensor not stabilized, or external interference. | Ensure the device is not near drafts, direct sunlight, or heat sources. Allow 10-15 minutes for the sensor to stabilize after moving or powering on. Avoid placing it in enclosed spaces. |
| Device resets (time, history, settings) after a brief power interruption. | Lack of internal battery backup for short power outages. | This device does not have an internal battery to maintain settings during power loss. Re-enter time and desired settings after any power interruption. Ensure a stable power connection. |
| Display backlight is too bright or difficult to view. | Display brightness settings or viewing angle. | Adjust the backlight settings using the 'Mode' and '+' buttons. The display has a limited viewing angle; try adjusting the device's position or your viewing angle. |
