4.4.3 Three-wire measurement of protective lead resistance using 10/25 A
current
Connect the mains plug of the tested device into the test socket of the me-
ter. Use the power probe (or Kelvin crocodile clip) connected to
U2
and
I2
sockets and touch metal parts of the tested device connected to PE.
The method of measurement and observations are the same as for the measurement of 200 mA.
4.4.4 Four-wire measurement of protective lead resistance using 10/25 A
current
Connect one probe (or crocodile clip) connected to
I1
,
U1
sockets, to PE of
power cable of the tested device. Use the power probe (or Kelvin crocodile
clip) connected to
U2
and
