* Accuracy is fulfilled by > 90% of the sensors after calibration. The indicated accuracy is
conserved only if the automatic calibration is activated or if the manual calibration is done
regularly. For proper function of the automatic calibration algorithm, the sensor has to be
exposed to air with CO2 concentrations <400 ppm regularly, considered as "fresh air"(please,
refer to the dedicated calibration section).
