4. Operating Instructions

4.1 Understanding the Display

The monitor's display provides real-time readings for various air quality parameters. Refer to Figure 2 for a visual guide to the display layout.

HCHO (Formaldehyde): Measured in mg/m³.
TVOC (Total Volatile Organic Compounds): Measured in mg/m³.
PM1.0, PM2.5, PM10: Particulate matter measurements in µg/m³. The device cycles through these readings every few seconds.
AQI (Air Quality Index): A numerical scale indicating overall air quality.
Temperature: Displays current ambient temperature in °C or °F.
Humidity: Displays current relative humidity in %.
Time: Shows the current time.
Battery Level: Indicates remaining battery charge.
