3)Drive in the screws, and pay attention to about 4mm
exposed. Then hang the CO2 meter up.
4）Connect one end of the USB cable to the USB power
adapter, and the other end （round connector）to the
power input port on the side of the device(input voltage ：DC5V )

Working method
Under normal working conditions, don’t do any settings,
just plug USB port to the power adapter and the DC
round head into the device. You can test the current CO2
value and temperature and humidity in real time.
During the first use, please Turn on device and keep
more than 24 hours, the device will automatically
calibrate. (Do not power off and restart halfway when
calibration)
