8.7.4 Leakage Current from the Applied Part – IA
Direct Measuring Method
– Direct measurement type (P1)
– DUT mains plug (PC1) connected to test socket
– Probe to P1 Terminal
Schematic Diagram
The device under test (PC1) is operated with mains power.
The measurements must be performed with mains plug polarity in
both directions. Polarity is reversed with the NL/LN key. After acti-
vating test voltage and line voltage, leakage current from the appli-
cation part is measured between the short-circuited terminals of
the applied parts and PE (DUT mains plug).

Alternative Measuring Method
(equivalent patient leakage current)
– Alternative Measurement Type (P1)
– DUT mains plug (PC1) connected to test socket
– Probe to P1 Terminal
Schematic Diagram
After activating test voltage, leakage current from the application
part is measured between short-circuited conductors L-N-PE
(DUT mains plug) and the short-circuited terminals of the applied
parts.
Wiring Diagram
Direct Measuring Method
– Permanent connection measurement type (P1)
– Permanent connection
– Probe to P1 terminal
Schematic Diagram
Leakage current from the application part is measured between
the short-circuited terminals of the application parts and PE at the
mains connection.
