MHZ19 should disable ABC mode (Auto Base Calibration ...

06/08/2017· The MHZ19 sensor has ABC enabled from factory, or at least two of my sensors now have their baseline messed up because the ABC mode was not disabled. The automatic base calibration will set the lowest measured internal RAW value in the last 24h as new reference point at 400 ppm. This means the base line will make a big jump when being used in a not well ventilated room for more than …
