12.If necessary, press to overrule the stability control. In this case, a calibration
happens immediately.
The new measured value is displayed for confirmation.
The result is displayed as follows:
single-gas calibration successful.
single-gas calibration failed.
13.The single-gas calibration is complete when measuring channel successfully
passed or failed the single-gas calibration.
► Select and then confirm the dialog to discard the result.
► Select to confirm the result.
14.Close the valves on the test gas cylinder.
If there was an error during the single-gas calibration:
– Repeat the single-gas calibration.
– Inspect the sealing contours and surfaces on the calibration adapter as well as
the front cradle of the housing to make sure they are free of damage. Inspect the
thread port for the calibration adapter.
– If necessary, replace the sensor.For further information, see the following

6.4.3 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.
To carry out a multi-gas calibration:
