Questions & Answers:
Q: How to test in normal condition?
A: Start up device for 10 minutes (at any place) , then you can check out the data on the display screen.

Q: How to get formaldehyde readings accurately?
A: 1. Keep the indoor environment ventilate.
2. Closing all doors and windows for 12 hours.
3. Do not use perfumes, facial-creams, make-ups, cooking condiments, and things contain artificial chemical ingredients near the device, to avoid interference of high reading values.

Q: Why the VOC value always stayed 0?
A: The reason is that you did not reset the device for the first time. Please follow the above procedures to operate it in outdoor environments.

Q: HCHO readings suddenly increased to a high value?
A: If you encounter the situation of sudden increase in formaldehyde, pay attention to the environment whether in your room there is cooking, alcohol using, perfume spreading (fragrance gas), smoking, or other interference. During the formaldehyde testing, you need to avoid these artificial cross-interference matters. For the standard test we recommended first ventilation, then sealed the room for 12 hours. This operation mostly takes in new decoration rooms or none settled-in rooms.

Q: Can I stay in the new house while the HCHO reading is around 0.08 ~ 0.09?
A: If the test of the room is at night, and it has been someone settled in the room. Then this value could be caused by windows and doors sealed too long, cooking fumes, or none ventilation air and other chemical interference, etc. Generally by opening the window, making the air ventilate again, the values can drop to 0.05 or less, the house is in good condition to live in, there is no need to worry. If it is a new home, no one settled in, and there is no human behaviour interference, the reading value is around 0.09,  or more than 0.1, then you can not move in, keep the house`s air ventilate for a period of time, then check it again before consider moving in.

Q: Components did not plug in? How to check it out?
A: This device is using hot-swappable parts design, if one of the components probe is not plugged in, the screen values will display N / A.
