Taking into account the slow circulation speed at the level of sensitive elements, the measurement of CO
2
is not affected by dust or water vapour. The
sensor does not require recalibration during its life cycle. It has two infra-red sources with different operating cycles, which enables it to be recalibrated
automatically.

Proportional Mode:
(press start-up between 5 and 10 secs):
The average over the 10 mins should be
greater than 1,100 ppm to be at 100% for
the following 10 mins.
