1) The set capture range can be read out on the gas detector and activated or deactivated. The
capture range is activated in measuring mode ex works. The capture range is always deacti
-
vated in calibration mode.
2) An LEL factor can be adapted to national regulations using the Dräger CC-Vision PC software.
