Self-calibration
At least once per week the Gas Mixer must be either turned
off for five minutes or the CO
2
concentration must be set to
0% for five minutes This is necessary for the sensor’s on-
board automatic calibration routine, which needs an atmo-
spheric CO

measurement to combat sensor drift.
