• Correction function (calibration function)
• If the correction function is ***d continuously for 5 to 7 days with the power ON, accurate automatic correction (calibration) is performed.
• < Automatic Calibration (Correction) >
• It dep***s on the product, but it is a function that considers the minimum measured value of carbon dioxide for 5 to 7 days to be 400PPM and corrects gradually.
• The reason for the reference value of 400PPM is that the World Meteorological Organization (WMO) has announced that the global average of 1 week's CO2 concentration is 400PPM, which is the reference value of 400PPM.
