Available test types
Test Type and
duration
Perform the test Description
System test Auto-
matic,
about 8
min
– Daily
– After service activities
Initialization:
– Checking of components which fre-
quently cause operational restriction:
e.g., high leakage, incorrect setting
of APL valve.
Test:
– Calibration of all valves and sensors
– Test of all device functions
– Includes the leakage test
– The test can be programmed, see
page 136
Leakage test Auto-
matic,
approx.
2min
– After filling the CO
2
absorber
– After changing the hose
configuration (e.g.,
changed hoses,
changed lengths of
extendable hoses etc.)
– After replacing the
breathing system
– After replacing the flow
sensors
– Calculation of leakage, system com-
pliance, and system resistance
– Calibration of valves and flow sen-
sors, if required. In this case, the test
is extended by approx. 3 minutes.
Leakage assistant Manual,
as
required
– After occurrence of prob-
lems with leakage during
automatic tests
– If leakage in breathing
system and breathing
circuit is suspected
– If leakage at vaporizer is
suspected
– If coaxial breathing cir-
cuits are used
– Continuous display of the test pres-
sure and the leakage to support the
manual check. Changes are immedi-
ately visible.
– Leakage test of a connected vapor-
izer
– Leakage test of the inner hose of a
connected Dräger coaxial breathing
circuit. Use the coaxial test adapter
for this. For more information, see
page 124.
