Description of Calibration Auto Calibration: Rough installing and influence of transportation might result in reducing of sensor measuring accuracy and baseline drift, sensor will correct the drift by the built-in self-correcting logic, and the auto baseline correction period is 24h+7 days. Powering on the sensor for 24 hours continuously, it will record the lowest CO2 concentration measurement value during the 24 hours, which will be regarded as baseline (400ppm) when sensor do auto calibration after the 24 hours working, and then the sensor will enter regular 7 days correction cycle, auto...
