– Momentary line voltage at the
SECUTEST test instrument is out-
side of the range permitted for a
10 A/25 A-R
PE
measurement (110
to 120 V or 220 to 240 V).
➭ Th
e 10 A/25 A-R
PE
measurement
is only available when line voltage
is between 220 V and 240 V or
110 V and 120 V at 50 Hz or
60 Hz.
➭ If you’r
e working with the SECUT-
EST in a system which does not lie
withi
n this voltage range, use one
of the 200 mA test currents in
order to determine protective con-
ductor resistance.
– IT system option (see section 4.1.1
Measurements in IT Systems) is
activated. 
An attempt has been made to
la
unch an active leakage current
measurement or a measurement
that refers to the PE at the mains
connection end (or a test sequence
which includes such measure-
ments).
➭ Selec
t measurement type 
"passive"
or
➭ P
erform the requested tests in a
TT/TN system rather than in an IT
system and configure the SECUT-
EST for that purpose.
or
➭ De
activate the leakage current
measurements in the sequence
parameters if possible.
Connection Error at the Test Socket
– Test probe P1 is not connected.
Or
– The test instrument’s 10 A/25 A
transformer is overheated.
Or
– One of the fuses has blown (fuse
h
older 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
is not suitable for continuous
operation!
– A short-circuit has been detected
at the test socket between L and
N.
➭ De
termine 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 resistor (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-I I I E).
➭ You can skip over this short-circuit
message at your own risk and
place the device under test into
service. Any damage resulting from
skipping over this warning is ex-
cluded from the guarantee!
