Calibration

CO2 Concentration Calibration

The device features a calibration function for the CO2 concentration value to ensure accuracy. This process should be performed in a well-ventilated area, away from people, to ensure accurate baseline readings.

  1. Ensure the device is powered off.
  2. Take the device to a well-ventilated outdoor area.
  3. Press and hold all three buttons (Power, DOWN, UP) simultaneously.
  4. The product will enter the automatic calibration state for 200 seconds. The screen will display a countdown.
  5. Once the calibration is complete, the device will return to normal operation.

AQI Alarm Function

The device provides visual and audible alerts based on the Air Quality Index (AQI) levels. The AQI is categorized into three stages:

  • Normal Mode: AQI 0-50 (Green indicator)
  • Warning Mode: AQI 51-100 (Yellow indicator)
  • Danger Mode: AQI 101-500 (Red indicator)

When the AQI index exceeds 100 (Danger Mode), the device will emit an audible alarm. To stop the alarm sound, press the "UP" button (marked with '+').
