1) Evaluated only is the sensor is intended for this purpose.
2) Corresponds to the averaging time and is used to calculated the STEL
exposure level.
3) Corresponds to the averaging time and is used to calculated the TWA
exposure level.
4) The deactivation of the ATEX-conformity leads to the loss of the tech-
nical suitability test.
