Perform the test:
1. Touch the Start button.
a. Wait until the leakage value is stable. Memorize the value.
b. Set the anesthetic gas concentration on the vaporizer to >0.2 Vol% (>2 Vol%
c. Wait until the leakage value is stable. Memorize the value.
d. If the two values differ from one another by more than 50 mL/min, check the
e. Set the anesthetic gas concentration to 0 Vol%.
2. Touch the OK button to switch back to the display of available tests.

Checking a coaxial breathing circuit for leaks with the leakage assistant
With a coaxial breathing circuit, it is always necessary to test the inner and the outer
hose. The inner hose of a coaxial breathing circuit cannot be checked by the normal
system test.
The leakage assistant can be used to determine the leakage of the inner hose of
Dräger coaxial breathing circuits with the help of a special test adapter. To do so,
the inner hose has to be directly connected to the expiratory port of the breathing
system via the test adapter.
Prerequisites:
– All flow control valves of the gas mixer are closed.
– The vaporizers are closed.
– The APL valve is set to 30.
– The Verify O
deactivated in the system setup (see "Vertical tab "System test"", page 219).
1. To test the inner hose, connect the breathing circuit as follows:
a. Connect the hose (1) to the inspiratory port (2).
b. Connect the coaxial test adapter (3) to the expiratory port (4).
c. Remove the elbow (5) from the hose (6). Connect the hose (6) to the coaxial
