Notes:

Due to transportation, vibration, aging and other reasons,
the carbon dioxide sensor may cause the zero drift and the
detection accuracy is reduced. In order to restore the
accuracy of the sensor, manual calibration can be adopted
to correct the drift. During the calibration process, place
the product in an environment with an outdoor atmospheric
CO2 concentration level (about 400ppm) to ensure that the
CO2 concentration in the environment is stable.

Due to transportation, vibration, aging and other reasons,
the carbon dioxide sensor may cause zero drift and reduce
the detection accuracy, so the sensor will correct the drift
through the built-in automatic calibration algorithm. About
48 hours after sensor start, will be stored within 48 hours
minimum carbon dioxide concentration values, to amend
the basic value of the atmospheric environment outdoor
carbon dioxide concentration(about 400ppm), since the
time of about 7 days, will be stored within 7 days of the
lowest carbon dioxide concentration values, to amend the
basic value of the atmospheric environment outdoor
carbon dioxide concentration (about 400ppm).The cycle
was then repeated for 7 days.Please ensure that the CO2
concentration is reduced to the outdoor atmospheric
level(about 400ppm) within about 48 hours after the
