Functional verification
Functional verification overview
This section describes the procedure for a complete functional test to support
recommended preventive-maintenance schedules.
The verification includes tests for a monitor configured with the printer, temperature, and
SpO
2
options. Perform only the tests applicable to the actual configuration.
A checklist of the functional tests is provided on “Checklist and test results report form”
on page 31. It is recommended that you print a copy of the checklist each time you
perform the functional verification procedure, so that you can record and save the test
results. If the monitor ever requires service, the records of test results can often facilitate
troubleshooting.
Functional verification does not require opening the monitor case.
