General notes
– This device may only be used in pollutant-free non-precipitating air without above-atmospheric or below-atmospheric pressure at the sensor element.
– The CO2 sensor is shock-sensitive. Due to the mechanism's design, the measuring result may vary if shaken.
– Dust and pollution falsify measurement results and are to be avoided. Slight pollution and dust sediments can be removed by using compressed air.
– In case of pollution, we recommend cleaning and recalibration in the factory.
– In any case, the sensor must not get in contact with chemicals or other cleaning agents.
– The device must be connected to one power supply only.
If you use the USB socket for power supply (5V), the connection terminals on the circuit board must remain unused, and vice versa.
– A cyclical fresh air supply must be provided because incorrect measurements can occur.
– The device must be permanently energized to measure the CO2 concentration correctly.
– If this device is operated beyond the specified range, all warranty claims are forfeited.
Our "General Terms and Conditions for Business" together with the "General Conditions for the Supply of Products and Services of the Electrical and
Electronics Industry" (ZVEI conditions) including supplementary clause "Extended Retention of Title" apply as the exclusive terms and conditions.
In addition, the following points are to be observed:
– Devices must only be connected to safety extra-low voltage and under dead-voltage condition.

from the catalogue representation are not explicitly mentioned and are possible in terms of technical progress and continuous improvement of our products.
– In case of any modifications made by the user, all warranty claims are forfeited.
– This device must not be installed close to heat sources (e.g. radiators) or be exposed to their heat flow.
Direct sun irradiation or heat irradiation by similar sources (powerful lamps, halogen spotlights) must absolutely be avoided.
– Operating this device close to other devices that do not comply with EMC directives may influence functionality.
– This device must not be used for monitoring applications, which serve the purpose of protecting persons against hazards or injury,
or as an EMERGENCY STOP switch for systems or machinery, or for any other similar safety-relevant purposes.

Once the aforementioned values have been reached, the respective LED becomes active
(with increasing luminosity of 20 %, 40 %, 60 %, 80 % and 100 %);
LEDs that are already active continue to be illuminated.
