68 GMC-I Messtechnik GmbH
– A device under test is connected to
the SECUTEST and has been
started up, whose leakage current
(measured by means of the differ-
ential current method) exceeds the
limit value specified in setup.
➭ If the device under test normally
generates a leakage current of
greater than 10 mA (e.g. large
heaters), temporarily increase the
“residual current protection” value
selected in setup to 30 mA and try
again.
➭ If
values of this magnitude are not
to be expected for the respective
device under test, or if the “residual
current protection” value has al-
ready been set to 30 mA in setup,
ther
e may be a ground fault at the
DUT.
– The fuse for the test socket’s L
conductor has blown (fuse link 2).
➭ Disconnect the test instrument
from the mains and inspect the
fuses next to the SECUTEST’s
mains connection.
– The fuse for the test socket’s N
conductor has blown (fuse link 1).
➭ Disconnect the test instrument
from the mains and inspect the
fuses next to the SECUTEST’s
mains connection.
– One of the two fuses for the test
socket has blown (fuse link 1 or 2).
➭ Disconnect the test instrument
from the mains and inspect the
fuses next to the SECUTEST’s
mains connection.
– A short-circuit has been detected
at the test socket between L/N and
PE.
➭ Determine whether or not the de-
vice under test is defective. Repeat
the vi
sual inspection.
