Direct Measuring Method
–
Measurement type APP - P2
– DUT mains plug (PC1) connected to test socket
– Probe to P2 terminal
– APPs to APP sockets
Schematic Diagram
Leakage current from the applied part is measured between the
applied parts connected to the APP sockets at the test instru-
ment and exposed, conductive parts (test probe P2), which are
not connected to the housing.

This measurement only detects the portion of the leakage current which is gen-
erated due voltage coupling at the DUT’s measuring input.
