NOTE: Due to the differences in test meters battery polarity, results other than specified may be obtained. In
such a case, reverse meter leads and re-test. If test results then read as specified on all tests CDM is O.K.. The
diode measurements above will be opposite if using a Fluke
equivalent multimeter.
