Safety Tests
This section covers tests of the defibrillator’s electrical safety.
These safety tests only need to be performed if the customer normally uses the
defibrillator with the AC Power Module connected. If the defibrillator is nor-
mally used on battery power only, these tests do not need to be performed.
Using the procedures called out by the manufacturer of the analyzer in use,
measure and record the following data. Only test at the AC Mains (line) volt-
age used in the customer’s facility - there is no need to test both 120VAC and
240VAC. Also, test both Normal and Reverse Polarity line connections, and
record the worst case value.
