• the integrity of all relevant accessories.

Power On Test

1 Switch on gas analyzer and patient monitor and check for any INOP messages after the warmup
phase. Make sure that the gas analyzer is not in Standby.
Wait for 12 minutes and make sure that no gas analyzer related INOP messages appear (except
2
"GM No Breath", "GM Alarm Suppress", "GM CAL RUNNING" or "GM ZERO RUNNING).
Ensure that the displayed values correspond to the ambient air (21% O
The expected test result is pass: No unexpected INOP messages and correct ambient air values.

Safety Tests

Safety tests are comprised of the following tests performed on the monitoring system:
• protective earth resistance
• equipment leakage current
Safety test requirements are set according to international standards, their national deviations and
specific local requirements. The safety tests detailed in this Service Guide are derived from
international standards but may not be sufficient to meet local requirements. We recommend that you
file the results of safety tests. This may help to identify a problem early particularly if the test results
deteriorate over a period of time.
Each individual piece of equipment which has its own connection to mains or which can be connected
or disconnected from mains without the use of a tool must be tested individually.
Accessories which can affect the safety of the equipment under test or the results of the safety test must
be included in the tests and documented.

Warnings, Cautions, and Safety Precautions

• These tests are well established procedures of detecting abnormalities that, if undetected, could
result in danger to either the patient or the operator.
• Disconnect the device under test from the patient before performing safety tests.
• Disconnect the device under test from mains before performing safety tests. If this is not possible,
ensure that the performance of these tests does not result in danger to the safety analyzer operator,
patients or other individuals.
• Test equipment (for example, a Safety Analyzer) is required to perform the safety tests. Please refer to
Annex C of IEC/EN 62353 for exact requirements for the measurement equipment and for
measurement circuits for protective earth resistance and leakage currents. Refer to the
documentation that accompanies the test equipment. Only certified technicians should perform
safety testing.
• The consistent use of a Safety Analyzer as a routine step in closing a repair or upgrade is emphasized
as a mandatory step to maintain user and patient safety. You can also use the Safety Analyzer as a
troubleshooting tool to detect abnormalities of line voltage and grounding plus total current loads.
• During safety testing, mains voltage and electrical currents are applied to the device under test.
Ensure that there are no open electrical conductive parts during the performance of these tests.
Avoid that users, patients or other individuals come into contact with touch voltage.
