How to use
•Switch on / off: In the case of shutdown, press the switch button, the screen lights up, the instrument needs to warm up for 5 minutes before normal measurement can be performed; in the measurement interface, press the switch button to complete the shutdown.
•After receiving the detector, put the battery into the battery box and turn on the instrument. After the sensor is warmed up, take it outdoors or place it on the window sill for 5-7 minutes. Long press the calibration key for 5 seconds and release it. \"Single, the interface displays the number 8 one by one, indicating that the zero calibration is completed, you can take it indoors for testing. (Don't be near the roadside, smelly ditch, garbage bin, industrial pollution area, etc. during outdoor calibration).
•Place it inside the sofa, desk, floor, bed or furniture, and place the instrument in the place to be tested for 5-7 minutes. After 5-7 minutes, the reading displayed on the instrument screen is the detected formaldehyde and TVOC content, and then Get the second location for detection (no need to press the calibration key again), which is also based on the reading after 5-7 minutes of placement, and the method for changing the detection location can be deduced by analogy.
