7. Disconnect the leakage tester from the wall receptacle.
8. Disconnect all test equipment from the device.
9. Disconnect the device power cord plug from the leakage tester power
receptacle.
Verify the power cord being used with the 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 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 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.
After re-assembling the monitor, ALWAYS complete the checkout
procedures, electrical safety tests, and regular maintenance procedures
identified and described in this manual.
