Sequence
Current, which would flow during leakage current measurement con-
ducted in accordance with device regulations and with nominal line volt-
age, is displayed during this type of equivalent leakage current measure-
ment.
Leakage current measurement in accordance with the respective device
regulations is usually not possible, because the device would have to be
set up in an electrically isolated fashion, or connected to an earth isolated
power supply to this end.
Equivalent Leakage Current I
EL
DIN VDE 070x / 2 K
Select the I-EL measurement and start.
Equivalent leakage current is measured between short-circuited N and L,
and the protective conductor PE.
Measuring circuit resistance is equal to 2 kΩ for VDE 0701/0702 for
simulation of mean body resistance of a human being.
Equivalent Device Leakage Current I
EDL
for VDE 0751 / 1 K
Select the I-EDL measurement and start.
Equivalent device leakage current is measured between short-circuited N
and L, and the probe.
Measuring circuit resistance is equal to 1 kΩ for VDE 0751 for the
simulation of mean patient resistance.
9.5 Probe Voltage U
probe
– Max. 300 V
Voltage is measured between the mains PE terminal at the test instrument
and the probe. In this case the probe can also be used as a phase finder.
Start the U
probe
measurement.
