The product conforms with the provisions of EU guidelines.
1.1.1. Accuracy of the measurement
Measurement variations from sources of interference (see chapter Installation posi-
tion ) must be corrected in the ETS in order to ensure the specified accuracy of the sen-
sor (offset). To ensure a correct CO
2
measurement, the device must be installed in a
windproof socket.
The indicated accuracy of the CO
2
measurement will be achieved after a run-in pe-
riod of 24 hours (without interruption of the bus voltage) if the sensor has been in con-
tact with fresh air (350…450 ppm) at least once in this period.
After this, the CO
2
sensor will recalibrate every two weeks by defining the lowest meas-
ured value captured during that period (without interruption of the bus voltage) as a
reference for fresh air.
