2.6 Test System Verification
Test leads should be checked for continuity and integrity before use. The best means for
checking lead integrity and correct operation of the equipment is to perform the FRA self-
check using a standard test object. This check is especially valuable for checking FRA test
equipment, since there is generally no intuitive way of knowing if the test equipment is
giving correct results when making field measurements.
