15.8.4 Leakage Current from the Applied Part – IA
Direct Measuring Method
–
Measurement type: direct 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. Switching takes place via the polarity softkey.
After activating
test voltage and line voltage , leakage current from
the applied part is measured between the short-circuited termi-
nals of the applied parts and PE (DUT mains plug).

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