Product Description
Fault description:
The machine suddenly shut down by itself, rebooting only lasts a second or two, or it can not turn on.
Solution: If the TF memory card is full, please replace it with a new card in time. Otherwise, there may be a sudden automatic shutdown of the machine, and can not open the machine.
If the above problems occur, try the following steps to rectify the fault:
1. Take out the TF memory card on the bottom of the machine
2. After power off, connect the charger to charge for more than 6 hours and then turn it on without the TF memory card to see if it can work.

The percentage of constant constituents in the air is almost constant within 100km from the ground. In terms of volume content, oxygen accounts for approximately 20.95%, nitrogen accounts for approximately 78.09%, and CO2 is approximately 0.03%. The carbon dioxide concentration in the atmospheric environment is very stable, with a value of about 400ppm, even in a clean environment.

Precautions for Use
Regarding machine reading is high on first use Reason: Because the packaging material itself contains interference gas, and it is sealed in the box for a long time, the charge attached to the surface of the sensor will increase, causing the value of the machine to be biased when it is turned on. Solution: After receiving the machine, put it in an outdoor clean and ventilated environment for about 8 hours, so that the charge can be released. (Charger can be connected to ensure the power supply)
Regarding the high TVOC level Please check your measuring point if there are some human activities such as cooking, smoking, drinking or some chemical gases such as perfume, air freshener, detergent, etc. Then try to put the machine in an outdoor clean and ventilated environment for more than 3 hours to see if the machine value will drop.
About CO2 sensor calibration The CO2 sensor adopts 72-hour automatic baseline calibration. Plug in the charger, turn on the machine, click the test button, and let the machine run continuously for more than 72 hours.
About TVOC and HCHO calibration
We should calibrate the equipment in fresh outdoor air, because particulate pollution and chemical pollution are two different types of pollution. Very low particulate matter does not mean that chemical pollution and interfering gases do not exist.
To verify whether the machine sensor is normal, please pick up the machine to the mouth, blow hard into the air inlet of the machine, see if the value changes.
Test purifying effect of purifier: light a cigarette in a room, place our machine in this room, wait for the readings to go up, and then place the machine next to the hePA filter in another room to see if the high readings go down.
Put our machine directly next to the purifier and the reading might not change much. Because there is no change in the air concentration in a normal environment, and when you turn on the purifier, it is impossible to make the reading of air quality monitor become very low.
To ensure accurate readings, please test more than 20 minutes: After the machine is turned on, click the yellow test button and the machine will start reading. When the machine is just started to run, the value is constantly changing, because it takes a process for the value to rise from 0. After the machine runs for about 20 minutes and the reading tends to be stable.
When we test the air quality in a room, in order to ensure accurate results, we should keep the machine away from some interference factors, such as some perfume, incense, freshener, detergent and other interference gases, as well as smoking, cooking, drinking, human breathing and other human interference factors.
