、The instrument adopts sampling mode through the free circulation and diffusion of air, and the air quality is different when the different time it enters the detector. So it is normal that the values go up and down for the same detection point. 4、Do not blow or block the sensor detection port of instrument.This will interfere with the normal operation of the instrument. 5、The instrument is a precision instrument ,please do not disassemble the housing and internal devices by yourself.
