Figure 5.29: Examples of differential current measurement result
Displayed results:
Main result I ........... Differential leakage current
Sub-result P............Apparent power
Notes:
For this test the instrument must be connected to the mains voltage.
During the test, 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.
Measurement can be aborted by pressing ESC key.
5.2.9 Touch leakage
This test determines the current that would flow if a person touches accessible conductive
parts of the DUT.
The instrument measures:
The touch leakage current flowing through the S/EB probe into earth.
The DUT can be powered from the test socket or directly from the installation (fixed
installed equipment).
