1 measurement cable red, 1 measurement cable black,
2 measurement cables blue,
2 alligator clips blue for contacting the welding electrodes,
1 set of operating instructions German/English
Applications
In conjuction with a multimeter or a SECUTEST... test instrument, the
SECULOAD-N test adapter is designed for testing welding equipment
(subsequenly referred to as device under test or DUT) in accordance
with standard EN 60974-4:2007. According to this standard, the peak
values of the off-load voltage may not exceed the limit values for any
possible setting.
Attention! The peak value rectifier of the SECULOAD-N uses rectifier
diode 1N 4007 recommended by the standard. This diode is a power
rectifier diode and, due to its design principle, only suitable for voltage
sources with a low clock rate in the line frequency range or for voltage
sources with conventional transformers.
However, there is welding equipment in the market, which uses
pulsed voltage sources with considerably higher clock rates. The
equipment can produce pulses with high voltage which, in turn, are
not completely captured by the peak value rectifier of the SECULOAD-N.
In these cases, the voltage issued by the SECULOAD-N may be dis-
tinctly below the peak values in the output voltage of the welding
equipment. It is imperative that this fact be taken into account in eval-
uating the measured values!
Special case: Welding instruments with an open-circuit voltage of less
than 30 V *
In this case, the SECULOAD-N does not provides for any load control.
Measurements are performed with a load resistance of 5 k. For
such low voltages, load control can be neglected, so that the mea-
suring result is shown on the display even without pressing the START
key.
* For the purpose of verification, perform a direct voltage measurement of
your welding unit by using a multimeter or a SECUTEST... test instru-
ment (without having the test adapter connected in this case).
Special case: Welding instruments which deactivate open-circuit voltage
In this case, a certain key at the welding instrument must be pressed
consistently in order to prevent deactivation. Please refer to the oper-
ating instructions of the welding instrument or contact the manufac-
turer for details on such cases.
Safety Instructions
This instrument fulfills the requirements of the applicable European
and national EC guidelines. We confirm this with the CE marking. The
relevant declaration of conformity can be obtained from GMC-I
Messtechnik GmbH. The test adapter is manufactured and tested in
accordance with safety regulations IEC 61010-1/EN 61010-1/VDE
0411-1.
When used for its intended purpose, the safety of the operator, as
well as that of the instrument, is assured.
Please make sure that the output of the DUT is de-energized for connecting it
to or disconnecting it from the test adapter.
Before using the test adapter, the off-load voltage of the welding equipment
must be checked. Input voltages at the test adapter of more than 130 V are
not permissible and result in the destruction of the test adapter. In this case,
the welding equipment must be repaired prior to testing it with the test
adapter.
In order to protect the internal resistor against overloading between
the red and black socket connectors of the test adapter, these two
socket connectors may not be short-circuited. Wait until the measured
voltage is no longer applied and/or the respective capacitors are dis-
charged (this is performed automatically during operation with a
SECUTEST... test instrument).
If the test adapter should nevertheless be overloaded once, voltage
measurements are no longer possible. You are kindly requested to
send the test adapter to GMC-I Service GmbH for repair in this case.
The test adapter may not be used

Test Sequence
Carefully read the operating instructions before use, in particular the op-
erating instructions included with the test instrument with which you in-
tend to use the adapter.
A test procedure for welding equipment is integrated in the
SECUTEST S2N+w.
➭ For all other SECUTEST... testers, select measurement type UAC/
DC for individual measurements.
➭ Switch the DUT on and wait for approx. 5 seconds.
➭ Connect a multimeter with min/max value memory (e.g.
METRAHIT X-
) or a SECUTEST... test instrument (via test sock-
TRA
ets 2 and 3) with the output sockets of the test adapter.
The red socket marks the plus pole, the black socket the minus
pole of the DC voltage supplied by the test adapter. When using a
multimeter, activate its min/max value memory.
➭ Connect the welding current outputs with the input sockets of the
test adapter (blue sockets).
➭ Press and hold the START key at the test adapter. After about 1 to 2
seconds a rising test current is present and LED
➭ As soon as the maximum current is reached and the Stop LED
lights up, release the START key at the test adapter.
➭ Read out the maximum voltage value saved to the multimeter and
check whether it is below the maximum value specified for the re-
spective welding equipment.
In the SECUTEST... test instrument, the min/max values can be
displayed with key
as from firmware version 7.1.
➭ Separate the DUT from the voltage source.
!
Attention!
When the Temp. LED lights up, the test adapter must be
disconnected from the DUT. Allow the test adapter to
cool down for 10 to 20 minutes before using it again.
Note
Always disconnect the test adapter from the DUT when it is
not required in order to avoid unneccessary self-heating.
