Before starting the carbon dioxide self-calibration
function, please first place the device in a well-ventilated
environment and provide sufficient power. The
self-calibration function takes 180 hours (approximately
7.5 days); during this period the power of the device
cannot be turned off. Suggested optimal carbon dioxide
concentration is between 400~500 PPM.
Do not start the carbon dioxide self-calibration function
(ABC) in places with poor ventilation or where the
stability of the power system cannot be guaranteed for
extended periods of time in order to prevent unnecessary
damage to the sensor.
