Functional Verification
Welch Allyn CP 100 and CP 200 Electrocardiograph
Functional Verification Overview
This section describes the procedure for a complete functional test to support
recommended preventive-maintenance schedules.
A checklist of the functional tests is provided on
. It is recommended that you
print a copy of the checklist each time you perform the functional verification procedure,
so you can record and save the test results. If the electrocardiograph ever requires
service, the records of test results often facilitate troubleshooting.
Functional verification does not require opening the device case.
Full Functional Check
Whenever the electrocardiograph is serviced or problems are suspected, Welch Allyn
recommends a Functional Check.
