The value stored on the MHZ19 and is set to 400ppm. This is used as the zeroing point. Zero Calibration: This can be made in two ways: By pulling the zero HD low (0V) for 7 Secs, or be sending command 135 (0x87). As above, the Zero refers to the background CO2 value of 400ppm, not 0ppm. Currently testing is the ability to send an adjustment ...
