Mains-On-Applied-Parts-Leakage-Current Test
The Mains-On-Applied-Parts-Leakage-Current test measures the current that flows in
response to an isolated AC voltage applied between a selected applied part, or ALL
applied parts, and Earth (and any conductive part connected to the RED terminal). Figure
5-7 shows the electrical connections between the ESA601 and the DUT. The table below
the diagram indicates the position of switches in the diagram during the test. DUT power
is on.
The test is performed with
