Carrying out a multi-gas calibration

All sensors which can be calibrated and are released by the Dräger CC-Vision PC
software are included in the multi-gas calibration.
If no sensors are released, the multi-gas calibration menu item is not available.
With a multi-gas calibration, the sensitivity of the sensors is set to the respective
concentration value of the test gas.
Requirements:
– The gas detector is switched on and warm-up phases 1 and 2 are complete. The
user is signed in with the corresponding user level.
– A suitable test gas cylinder is available.
– The concentration values of the test gas cylinder are sent in the gas detector
using the Dräger CC-Vision PC software.
