Before starting the measurement, similarly to
sec. 4.2 , following parameters must be set: test volt-
age , test duration , limit and test method: probe-socket (measurement between shorted L-N and
PE of the test socket or T2 probe), probe-probe (measurement between T1 and T2 probes) or IEC
(IEC cord test).

Tested appliance must be turned on.
