• The device requires an operating time of approx. 10 to 60 minutes for a meaningful
measurement. In small rooms (such as cupboards, drawers etc.) the operating time is
approx. 3 to 15 minutes.
• A frequent fluctuation of the display is normal and shows the constantly repeated
measurements. The overall result is shown as the AQI value (3) .

Specifically by providing the value for the CO2 concentration in the air (8) , conclusions
can be drawn about aerosols with viruses (e.g. Covid 19) present in the air. Although
these are not directly detectable, increased CO2 pollution is at the same time a
measure of virus-contaminated air. This can be remedied by regular airing.
Permanently inhaling bad and stale air can cause tiredness, headaches, eye irritation,
etc. The ability to perform and concentrate decreases noticeably as a result.
The display of the concentrations of carbon monoxide
(9) , formaldehyde (7) and other
volatile compounds (2) also helps to ensure that remedial action can be taken in good
time by means of ventilation. Furthermore, the different displays can help to identify the
corresponding sources: e.g. formaldehyde emissions from furniture, wood panelling,
etc. Respiratory diseases can thus be prevented and a healthy indoor climate created.
7. Reset to factory settings (e.g. after relocation)
• Press and hold Reset (5) for around 3 seconds to reset the product to the factory
default settings.
• All previous measurements are permanently deleted.
