Connection Error at the Test Socket
–
Test probe P1 isn’t connected.
or
–
The test instrument’s 10 A/25 A
transformer is overheated.
or
–
One of the fuses has blown (fuse
holder in close proximity to the
mains input).
➭
Repeat measurement with probe P1
connected.
➭
Check the fuses and replace if nec-
essary.
➭
Select a different test current (e.g.
200 mA) or wait until the trans-
former has cooled down and then
repeat the measurement.
Attention!
!
The 10 A/25 A measurement
isn’t suitable for continuous
operation!
–
A short-circuit has been detected
at the test socket between L and
N.
➭
Determine whether or not the de-
vice under test is defective.
➭
In the case of DUTs which are intended
for operation at an outlet that’s pro-
tected with a 16 A fuse, a short-circuit
may be detected under certain circum-
stances if, for example, they include a
PTC thermistor (e.g. large floodlights).
Be sure to use a 3-phase test adapter
in order to test devices of this sort (e.g.
the AT3-IIIE).
➭
You can skip this short-circuit mes-
sage at your own risk and place
the device under test into service.
Any damage resulting from skip-
ping this warning is excluded from
the guarantee!
–
A device under test, whose leak-
age current (measured by means
of the differential current method)
exceeds the limit value specified in
SETUP, is connected to the test
instrument and has been started
up.
➭
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,
there 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 it’s mains con-
nection.
