NOTE!

During the measurement, the same mains voltage is present at the measuring
socket which powers the tested appliance.

During the measurement of a faulty appliance, RCD switch may be triggered off.

PE leakage current is measured directly in PE conductor, which gives an accurate
result even if the appliance consumes a current of 10 A or 16 A. Note that if the cur-
rent does not leak to PE, but to other earthed elements (e.g. water pipe)
– it cannot
be measured in this measurement function. In that case it is advised that the differ-
ential leakage current I
Δ
method of testing should be used.

Ensure that the location of the tested appliance is insulated.

When Change polarity is set on Yes , after the set time duration is over the tester
automatically changes the polarity of the test mains socket and resumes the test.
As a test result it displays the value of the higher leakage current.

If the tested appliance is damaged, signaling a 16 A fuse burnout may also mean
that the overcurrent protection device in the mains from which the meter is powered
has tripped.
