5. Calibration
For accurate readings, especially for CO2, calibration is recommended before initial use and periodically thereafter.
5.1 CO2 Calibration Procedure
Image 5.1: Steps for performing CO2 calibration.
- Charge the device for at least 5 minutes before using it for the first time.
- Place the monitor in a well-ventilated outdoor area for more than 10 minutes with the power on.
- Enter the calibration interface (press and hold Left and Right buttons simultaneously), then select "Yes" for calibration.
- The calibration will complete with a long beep from the buzzer.
6. Understanding Readings and Alarms
6.1 Air Quality Indicators
The monitor uses a color-coded system to indicate air quality levels for various parameters:
- Green: Good air quality.
- Yellow: Moderate pollution.
- Orange: Poor air quality.
- Red: Unhealthy air quality.
Image 6.1: Example of the multicolor indicator for PM2.5 levels.
6.2 Reference Table for Air Pollution Grades
Refer to the table below for specific concentration ranges corresponding to each air quality grade.

6.3 Audible and Visual Alarms
When any monitored value exceeds its normal threshold, the device will emit a ticking alarm sound, the indicator light will flash continuously, and the interface color will change to reflect the severity.

Default alarm values are:
- AQI: 100
- CO2: 1500 PPM
- PM1.0: 75 µg/m³
- PM2.5: 75 µg/m³
- PM10: 150 µg/m³
- HCHO: 0.1 mg/m³
- TVOC: 0.5 mg/m³

7.2 Care and Safety Guidelines
Image 7.2: Important safety and care instructions.
- Prevent Soaking: Do not place the product in bathrooms or areas where it may be drenched by water.
- Prevent Strong Vibration: Avoid strong shock or vibration, such as dropping the device.
- Stay Away from Volatile Substances: Do not place the product near volatile substances like perfume, alcohol, or mosquito coils, as these can interfere with readings.
- Prevent Obstruction of Gas Ports: Do not insert sharp, flammable, or metal objects into the monitor or air inlet to avoid short-circuiting or damage.
8. Troubleshooting
- Inaccurate Readings: Ensure the device has been properly calibrated, especially for CO2. Perform calibration in a well-ventilated outdoor area. Avoid placing the monitor near sources of strong odors or chemicals.
- Device Not Turning On: Check if the battery is charged. Connect the device to a power source using the Type-C cable and try again.
- No Sound/Alarm: Check if the sound function is enabled (press and hold the Left button).
- Screen Not Responding: Try restarting the device by holding the Multi-Function button. If the issue persists, ensure the battery is charged.
- HCHO/TVOC Readings Seem Low/Zero: These sensors may require a baseline period to stabilize. Ensure the device is used in a consistent environment for some time after calibration.
