Power outlet test
Verify that the power outlet is wired correctly per the country’s electrical
code standard before starting the following electrical safety tests. The
results of the following tests will be inaccurate unless a properly wired
power outlet is used. Use only non-isolated power outlets when
performing safety tests.
Power cord and plug
Verify the power cord being used with the patient monitor is good. The
following are a couple of things to check for in this regard:

Failure of the power cord strain relief is very common. Often times
users of the equipment pull on the power cord itself, rather than the
power cord plug, to unplug the patient monitor from a wall
receptacle. If in doubt, test for continuity through each conductor of
the power cord connector and plug.

Verify line, neutral, and earth conductors are properly connected to
the power cord plug and are not short-circuited. Replace the power
cord, as necessary with a regulatory-approved cord for the country of
use.
WARNING
Use only AC power cords recommended or manufactured
by GE.
