Leakage Current Offset

In leakage current testing, mains power is applied to the device under test (DUT) so that the resulting leakage current can be measured. This measured leakage current can be a combination of leakage current from the DUT, from the fixture and cables attaching the DUT to the test instrument, and also from the test instrument itself. The Offset capability inherent in Chroma’s Guardian Electrical Safety Analyzer 19032-P is very important because it measures the leakage current of the DUT not the leakage of the fixture, cables or the test instrument itself.
