5. Operating Instructions

The BT-5800S is designed for straightforward operation to monitor various air quality parameters.

5.1 Taking Measurements

1. Ensure the device is powered on and has completed its warm-up phase.
2. Place the device in the area where you wish to measure air quality. For accurate readings, ensure the air intake vents are unobstructed.
3. Press the RUN/STOP button to begin continuous measurement. The display will update with real-time readings for PM2.5, PM10, HCHO, and TVOC.
4. To pause measurements, press the RUN/STOP button again.

5.2 Understanding the Display

The LCD screen provides a comprehensive overview of air quality. Key indicators include:

• PM2.5: Particulate matter with a diameter of 2.5 micrometers or less. Displayed in µg/m³.
• PM10: Particulate matter with a diameter of 10 micrometers or less. Displayed in µg/m³.
• HCHO: Formaldehyde concentration. Displayed in mg/m³.
• TVOC: Total Volatile Organic Compounds concentration. Displayed in mg/m³.
• Hazard Indicator: A visual icon (e.g., happy, neutral, sad face) or color-coded bar indicating the overall air quality level based on the readings.
• Battery Indicator: Shows the current battery charge level.
• REC: Indicates data recording status.
• CAL: Calibration option.
• Set Up: Accesses device settings.
