Also, if the test fails, you should:
Verify that your test connections are correct.
Ensure the equipment connections are torqued to proper specs.
Ensure that cables and adapters meet specifications listed in the Required Test Equipment table.
Check cables and adapters for damage.
Check the input and output connectors on the test equipment for damage.
