Measuring the device leakage current according to the differential current method (mea-
suring setup according to (Fig.4/p.15)) is the preferred method, as the person carrying
out the measurement or other persons are not endangered during the measurement.
However, observe the minimum resolution of the leakage current measuring device and
additional manufacturer specifications which limit usage of the measuring device.
Fig. 4: Measuring circuit for measuring the leakage current according to the differential current
method in compliance with DIN VDE 0751-1/2001-10, Fig. C6 for protection class I.
Pos. 1 = System
Pos. 2 = Application part type B (if available)
Pos. 3 = Measurement setup (integrated into measuring device)
If direct measurement of the device leakage current is used (measuring setup according
to (Fig.5/p.16)), the system must be installed in an insulated way and must not be
touched during measurement.
