– 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).
➭ The 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’re working with the SECUT-
EST in a system which does not lie
within 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 Sys-
tems”) is activated. An attempt has
been made to start an active leak-
age current measurement or a
measurement with reference to PE
at the mains connection end (or a
test sequence which includes such
measurements).
➭ Select measurement type “pas-
sive”.
or
➭ Conduct the desired tests in a TT/
TN system instead of an IT system
and configure the SECUTEST ac-
cordingly.
or
➭ Deactivate leakage current mea-
surements in the sequence param-
eters 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
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.
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.
➭ 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 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-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!
