– 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 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.
