 Insert the shock-proof plug of the portable test sample into the
test socket of the appliance tester.
 The testing voltage is applied and must be tested in all switch
positions (device functions).
 Use the test probe to scan all accessible conductive parts.
 If the measured value of the alternative leakage current
measurement exceeds 1 mA, the direct current measurement
must be carried out.
Measurement
 Make sure that the test sample is free of mains voltage.
 Connect the mains plug of the test sample to the test socket of
the appliance tester.
 Select a measuring
