Tests
8.2 Available test types
8.3 Performing the tests
8.3.1 System test and leakage test
Prerequisites:
– Electronically controlled gas mixer: Central O
2 supply or central Air supply is
connected
– Mechanically controlled gas mixer: Central O
2 supply is connected
– The anesthetic gas receiving system is correctly connected.
Both tests consist of a checklist followed by an automatic test. The automatic test
consists of a pretest (the initialization), which may require manual actions by the
user, and a fully automatic main test.
System test
Type and duration: Automatic, approximately 8 min
Perform the test: Daily
Description: Initialization:
– Checking of components which frequently cause
operational restrictions: e.g., high leakage, incor-
rect setting of APL valve
– Calibration of the O
2 sensor (every 7 days)
The initialization takes approximately 2 to 3 minutes.
Remain by the device during this time. Make correc-
tions if necessary.
Scope of test:
– Calibration of all valves and sensors
– Test of all device functions
– Performance of leakage test
Leakage test
Type and duration: Automatic, approximately 2 min
Perform the test: – 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 inserting the piston diaphragm
– After replacing the flow sensors
– If leakage at vaporizer is suspected (see "Check-
ing a vaporizer for leakage", page 130)
Description: – Determining leakage, system compliance, and
system resistance
– Calibration of valves and flow sensors, if required.
In this case, the test is extended by
approximately 3 minutes.
