Preventive maintenance
Power source tests
Power outlet test
Verify with the facilities or biomedical maintenance department 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 safety tests will be inaccurate
unless a properly wired power outlet is used.
Power cord and plug test
Verify the power cord being used with the monitor is good. This can be accomplished
following the
Ground continuity test on page 10-6 .
 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 monitor from a power outlet. If in doubt, test for continuity through
each conductor of the power cord connector and plug.

Verify line, neutral, and ground conductors are properly connected to the power
cord plug and are not short-circuited. Rewire and tighten these, or replace the
power cord, as necessary.
Electrical safety tests
Electrical safety tests provide a method of determining if potential electrical health
hazards to the patient or operator of the device exist.
Electrical safety tests may be performed under normal ambient conditions of
temperature, humidity, and pressure.
The recommended test equipment is listed below.
Ground (earth) integrity
Listed below are two methods for checking the ground (earth) integrity. These tests
determine whether the device's exposed metal and power inlet's earth (ground)
connection has a power ground fault condition. Perform the test method that is
required by your country/local governing safety organization.
Ground continuity test
1. Disconnect the CIC Pro center under test from the power outlet.
