Long press the power button for 1-3 seconds to turn on.2. Quickly double-click the power button 1, and the CO2 value will be displayed.3. Click the button 2 to increase the alarm value, each increase of 100ppm, the highest can be set to 2000ppm.4. Click the button 3 to reduce the alarm value, each reduction of 100ppm, the highest can be set to 800ppm.5. Click the power button to confirm the alarm value setting.6. Click the power button to turn on/off the alarm.3-in-1 Device: The NDIR high-precision infrared sensor is multifunctional, can lock current environmental monitoring maximum value, used for CO2 measurement, temperature, and humidity.High Measurement Range: When CO2 is 0-5000ppm, the accuracy is about ±50ppm+5%, and the relative humidity is about 20%-85%, the storage temperature is about -10°C to 60°C.Long Standby Time: There is a built-in rechargeable lithium battery (about 1600 mAh), the long standby time of the air quality monitor can reach more than 48 hours. It is recommended to connect to the port during the entire working hours.Intuitive and Clear: Compared with the traditional old-fashioned air quality detector, the interface design of our monitor is more precise and intui
