Carrying out 1-button calibration
All sensors that are enabled by the Dräger CC Vision PC program take part in the 1-
button calibration.
In the case of the 1-button calibration, the sensitivity of all sensors is set to the value
of the test gas.
When using the test gas cylinder 68 11 130 = mixed gas with 50 ppm CO, 15 ppm

If a mixed gas with another
composition is used, the specified
concentration values in the device
must be changed to the target values
of the mixed gas used using the PC
software Dräger CC Vision.
Connect the test gas cylinder with the
calibration cradle.
Vent the test gas into a fume
cupboard or into the open air (with a
hose connected to the second
connector of the calibration cradle).
Switch on the device and insert it into
the calibration cradle until it engages.
Call the calibration menu, enter the
password and select the 1-button
calibration function, page 20.
Press the key to start the 1-button
calibration.
NOTICE
If no sensors are enabled for 1-button calibration by the Dräger CC Vision PC
program, the 1-button calibration menu function will not be offered.
CAUTION
Health hazard!
Do not inhale the test
gas. Risk to health!
Observe the hazard warnings of the
relevant Safety Data Sheets.
