5. Operating Instructions
5.1 Understanding the Display
The monitor features a clear color display that presents all detected parameters simultaneously. Refer to the diagram below for an explanation of each indicator:
Figure 3: Detailed breakdown of the monitor's display, indicating the location and meaning of each measurement and status icon.
- Speech State Icon: Indicates if voice prompts are active.
- Battery Capacity Icon: Shows current battery level.
- Temperature: Displays ambient temperature in Celsius.
- Humidity: Displays relative humidity in percentage.
- HCHO Concentration: Formaldehyde levels in mg/m³.
- TVOC Concentration: Total Volatile Organic Compounds levels in mg/m³.
- PM2.5 Concentration: Particulate Matter 2.5 levels in ug/m³.
- PM10 Concentration: Particulate Matter 10 levels in ug/m³.
- CO Concentration: Carbon Monoxide levels in ppm.
- CO2 Concentration: Carbon Dioxide levels in ppm.
- AQI: Air Quality Index, providing an overall assessment of air quality.
- Air Quality Level Bar: A color-coded bar indicating the current AQI level (Good, Slight, Moderate, Serious).
5.2 Button Functions
- Power Button (⑂): Press and hold to power on/off. Short press may cycle through display modes or confirm selections (refer to specific model behavior).
- Speaker Button (🔊): Short press to toggle voice prompts on/off.
- Function Button (Fn): Used to access additional settings or switch between different display interfaces if available. Consult the on-screen prompts for specific functions.
5.3 Interpreting Readings
The monitor provides real-time readings for all parameters. The AQI (Air Quality Index) and its corresponding color bar offer a quick visual summary of overall air quality:
- Green: Good air quality.
- Yellow: Moderate air quality, sensitive individuals may experience minor effects.
- Orange: Unhealthy for sensitive groups.
- Red: Unhealthy for everyone.
- Purple/Maroon: Very unhealthy/Hazardous.
For specific pollutant levels, refer to local or international air quality guidelines to understand safe and unsafe thresholds.
6. Maintenance
6.1 Cleaning
Wipe the device gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water. Ensure the air inlets and outlets are free from dust and obstructions.
