2. Meanwhile, please put the detector in a ventilated place for 10 minutes and the equipment will do calibration automatically. When the backlight symbol on the display screen stops flickering, the calibration is finished.

Therefore, please keep away from such materials as alcohol cosmetics contain alcohol perfume, etc. ) cigarettes (containing carbon monoxide), smoke(containing acrylic acid) and fruits (containing ethyl alcohol) before detection.
5. It's better to close the windows and doors for 10 minutes at first before testing formaldehyde in bedrooms, sitting rooms and cloakrooms. The average value of various locations test data in a room is the average content of formaldehyde in the room
