EURANEG ALOAIR 20001 1 Instrucciones De Uso página 52

Due to a mechanical shock or a strong vibration, the measuring chamber in the
sensor can easily deform. The result is that the sensor has an "offset" and
displays yellow / red even with fresh air. This does not at all mean a defect of the
AirCop, but only an "offset" of the sensor. Since the AirCop can recalibrate
itself, this is not a big deal.
The last case describes this effect:
The AirCop is "misaligned" and measures 840 ppm CO2 even with fresh air.
To recalibrate the sensor to the correct value, ensure that the AirCop receives fresh
air for at least 20 minutes for 7 consecutive days. After exactly 7 days, the sensor
will automatically detect that 840 ppm is the new minimum and reset this offset to
420 ppm CO2.
You can continue to use the AirCop as before.
