1. Application
The measuring adapter helps you to test portable devices. Due
to its robust design, it is particularly suited for being used in in-
dustrial environments. The measuring adapter is easy to use and
thus allows the user to work efficiently and quickly.
You can test devices and extension cables being provided with
the following connectors complying with IEC 60309-1.
CEE connector:
16 A, 50 Hz to 60 Hz, 230 V, L+N+PE, 6h
16 A, 50 Hz to 60 Hz, 380 V to 415 V, 3L+N+PE, 6h
32 A, 50 Hz to 60 Hz, 380 V to 415 V, 3L+N+PE, 6h
To do this, connect the measuring adapter to an appliance
tester for testing portable devices according to
DIN VDE 0701-0702, DIN EN 62353 (VDE 0751-1) or
DIN EN 60974-4 (VDE 0544-4).
For connection of the measuring adapter, the appliance tester
must be equipped with a shock-proof socket.
Depending on the type of test, a CEE 16 A or 32 A socket may
also have to be available. For the CEE 16 A, an optional adapter
cable (part no. 044163) is required.
The measuring adapter is suited to be connected to the fol-
lowing appliance testers:
BENNING ST725
BENNING ST750 / ST 750 A / ST 755 / ST 760
Devices of other manufacturers
The measuring adapter can be used for the following tests:
Protective conductor resistance (RPE)
Insulating resistance (RInsu)
Functional test and phase sequence test of cables
Alternative leakage current:
e. g. protective conductor current (IPE), contact current
(ICont),
device leakage current (ILeak), patient leakage current
(IPLeak)
Differential current measuring method
IPE
Leakage current
Direct measurement
Contact current
Patient leakage current
Functional test
Ua
Welding equipment (ST 760)
PRCD
The manufacturers’ specifications and normative re-
strictions with regard to alternative leakage current
testing and appliance tests must be adhered to.
To do this, thoroughly read the notes stated in the cor-
responding standard, in the manufacturers’ specifica-
tions of the test sample and in the operating manual of
the appliance tester.
1.1. General functional description
The MA 4 measures the fault current from the test sample using
the differential currentmeasuring method. This current is applied
on the N and PE line of the tester, so that this fault current can
be measured by testers using the differential current measuring
method or the direct measuring method with 1 kΩ in the PE of
the tester. Deviating measuring resistances in the PEcan lead to
an incorrect current applied.
2. Safety notes and precautions
2.1. Basic information about safety
The measuring adapter has been designed and tested incompli-
ance with the safety requirements according to
IEC/ EN 61010-1/ VDE 0411-1.
All electrically conductive parts of the housing are connected to
the protective conductor system (according to IEC 61140, pro-
tection class I).
The measuring adapter must be used only for testing in environ-
ments of measuring category CAT II according to
IEC/ EN 61010-1.
Make sure not to connect and test more than one test sample or
one extension cable at a time.
The measuring adapter must be operated under supervision
only.
In case of proper use according to the specifications, the safety
of both the user and the device is ensured.
Read this operating manual and the operating manual of the ap-
pliance tester carefully and thoroughly before using the product.
Please observe all instructions of the relevant operating manu-
als.
The measuring adapter must not be used:
with the housing being open,
in case of visible external damage,
in case of damage of the CEE connectors, CEE sockets,
connecting line or connector,
in case of strong excessive strain or if the load limits
stated in the technical data have been exceeded,
if the device has been stored under unfavourable condi-
tions for a longer period of time (high exposure to dust,
moisture or excessive temperatures).
Non-observance might involve damaging or destruction of the
measuring adapter and/or the connected test sample!

3. Inspection characteristics of the measur-
ing adapter
All tests that can be carried out with your appliance tester for de-
vices with shock-proof socket and that are supported by the
measuring adapter can now be performed in an identical way for
devices with CEE connector.
Please observe the following aspects during tests using
your appliance tester:
 When testing the protective conductor resistance, the value
of the measured protective conductor resistance increases
by the share caused by the protective conductor line of the
measuring adapter.
In case of measuring results near the admissible limiting
value, measure the protective conductor resistance of the
measuring adapter at the PE connection of its CEE socket
and subtract it from the totalmeasuring value of the system.
Alternatively, when using the appliance testers BEN-
NING ST755 / ST 760, a probe calibration can be carried
out at the PE connection of the CEE socket.
If the measuring adapter is not used, the probe must
then be calibrated again at the PE connection of the
appliance tester.
 During insulating resistance or alternative leakage current
tests, the three phases L1, L2, L3 and the neutral conduc-
tor N of the test sample are shorted.

5. Connecting the measuring adapter
The measuring adapter is equipped with a PTC ther-
mistor as short-circuit protection for cable testing, but
not for appliance testing.
Use the measuring adapter only for the intended tests
described in this manual.
The manufacturers’ specifications or normative re-
strictions with regard to all tests involved must be ad-
hered to.
To do this, thoroughly read the notes stated in the
corresponding standards, in the manufacturers’ speci-
fications of the test sample and in the operating man-
ual of the appliance tester.
Before you can start testing, you have to connect the measuring
adapter to your appliance tester.
To do this, proceed as follows:
Make sure that the appliance tester you are using is ready
for operation.
Connect the shock-proof plug of the measuring adapter to
the test socket of your appliance tester.
Connecting the measuring adapter to the appliance tester
This is a connection method for appliance testing and cable
testing.
For appliance testing, the MA 4 must be connected to the
mains. Connect the ST 755 / 760 to the socket of the MA 4.
Connection diagram
6. Testing with the measuring adapter
Testing the adapter for compatibility with third-
party manufacturers / self-testing the device
In the switchposition forappliance testing +1 mA and
in the switch position for appliance testing +3 mA, an
internal fault current is generated in the MA 4. The
fault current becomes detectable for the measuring
instruments when 230 V are applied to their test
socket. For appliance testing, the MA 4 must be con-
nected to the mains via the CEE 32 A cable. If such
a functional test is carried out, no fault current is gen-
erated in the switch position for appliance testing
without any test samples being connected. By select-
ing the position for appliance testing +1 mA, a fault
current of approx. 1 mA is generated. The fault cur-
rent depends on themains voltage. Now, it should be
possible tomeasure this faultcurrent bymeansof the
tester. The fault current is applied on the N conductor
and on the PE conductor of the measuring instru-
ment.
The current in the N conductor can be determined by
any measuring instrument using the differential cur-
rent measuring method. In order to detect the applied
current in the PE, a measuring resistance of 1 kΩ is
required. Otherwise, a deviating applied fault current
will occur. In case of the ST 755 / 760, this load is au-
tomatically selected as soon as three-phase meas-
urement has been activated.
For this test, no test sample may be connected!
Before carrying out the functional test and all tests
for which the test sample must be supplied with
mains voltage and put into operation, make sure
that there are no short-circuits in the test sample
within phases L1, L2, L3 and the neutral conduc-
tor N! Non-observance might involve damaging or
destruction of the measuring adapter and possibly of
the test sample as well!
Within the framework of the functional test, it is not
possible to determine the values of the power and
current consumption of the test sample by means of
the measuring adapter. The displayed values refer
to the power consumption of the measuring adapter
itself.

6.2. Testing of three-phase devices with alterna-
tive leakage current method
The alternative leakage current measuring method must not be
carried out as an alternative to insulating resistance measure-
ment. DIN VDE 0702 para. 5.7 expressly points out thatmeas-
uring the alternative leakage current is an alternative measuring
method for measuring the protective conductor current or con-
tact current after an insulating resistance measurement has
been passed. Exceptions are devices of protection class I with
switched on heating elements and a total connected load of
more than 3.5 kW. If such a device does not pass the insulating
resistance measurement, it is still considered to be in proper
condition if the protective conductor current according to para-
graph 5.5 of the mentioned standard is not exceeded.
