3. Connect the test gas cylinder hose to the adaptor (2).
4. Open the test gas cylinder valve to let test gas flow over the
sensors.
5. Wait until the device displays the test gas concentration
with sufficient tolerance:
Ex: ±20% of the test gas concentration
1 Upon application of the Dräger mixed gas (order no. 68 11 130)
the displays should be within this range. Different concentrations
can be set using the Dräger CC-Vision PC software provided.
