arduino MHZ19 calibration. What to do for a not ...

20200924· I have 2 MHz19 for measuring indoor CO2 calibration. One is running permanently on a Raspberry Pi, the other one with an Arduino Pro Micro on a handheld device, that is turned on only when I want to measure. The specs say that the MHz19 is auto calibrating every 24 hours. That feature can be turned off and it can be calibrated by sending a zero point calibration command. Does this zero point ...
