1) The set capture range can be read out with the Dräger CC-
Vision software. The capture range is continuously activated
in measuring mode and disabled in calibration mode.
2) An LEL factor can be adapted to national regulations using
the Dräger CC-Vision PC software.

the STEL exposure level.
3) Corresponds to the averaging time and is used to calculated
the TWA exposure level.
