3.2 Initial Power-On and VOC Sensor Preheating
After installing the battery or connecting via Micro USB:
- Press and hold the red power button (U) to turn on the device.
- When measuring VOC, the VOC sensor requires a preheating period of approximately 5 minutes for accurate readings. Ensure the device is powered on and allowed to stabilize before taking VOC measurements.
4. Operating Instructions
4.1 Power On/Off
- To power on: Press and hold the red power button (U).
- To power off: Press and hold the red power button (U) again until the device shuts down.

4.2 Switching Measurement Modes
Press the 'FUNC' button to cycle through the different measurement modes: Dust (PM2.5), VOC, Temperature, and Humidity. The current mode will be indicated on the LCD display.
4.3 Taking Measurements
Once the desired mode is selected, the device will automatically begin sampling and display the readings on the LCD screen.
- Dust / PM2.5: The device will display the PM2.5 concentration in µg/m³. The sampling cycle is 1 second.
- VOC: The device will display the VOC concentration in ppm. Remember to allow for a 5-minute preheating period for accurate readings. The sampling cycle is 1 second.
- Temperature: The device will display the ambient temperature in °C. The sampling cycle is 2 seconds.
- Humidity: The device will display the relative humidity in RH%. The sampling cycle is 2 seconds.
5. Applications
