Examples of differential current measurement result
Displayed results:
Main result ............. differential leakage current
Notes:
 During the test, a mains voltage is connected to the DUT. If DUT contains moving
parts, make sure that it is safely mounted or protected to prevent possible danger to
the operator or damage to the DUT or surrounding environment!
 Consider any displayed warning before starting measurement!
 The instrument automatically changes L and N polarity of connected DUT during the
test.
5.2.7 Touch leakage current
This test determines the current that would flow if a person touches accessible
conductive parts of the DUT.
The instrument measures the leakage current flowing through the EB/S probe into
earth.
The DUT can be powered from the mains test socket or directly from the installation
(fixed installed equipment).
