I think you might have it the wrong way round, as the product information mentions fresh air as a requirement for manual calibration, not automatic.
"If a drift of the CO2 measurements occurs, calibration feature of the device should be used. Auto calibration mode is utilizing ABC algorithm whereas
Manual calibration mode demands sensor to be exposed to fresh air."
"CO2 sensor of the device is calibrated at standard atmospheric pressure. CO2 readings are pressure compensated and comply with the
specifications down to 750 hPa. If the device has to be used at high altitude for a prolonged period of time, manual calibration of the unit should be
performed for optimal performance. It is not intended to use the device higher than 4000 m (13 000 ft) above the sea level."
