1 Safety Precautions
The test adapter has been manufactured
and tested in accordance with the following
safety regulations:
I
EC/EN 61010-1/VDE 0411-1,
DIN EN 61326-1/VDE 0843-20-1
Safety of the operator, as well as that of the
test adapter, is only assured when it’s used
for its intended purpose.
Use for intended purpose stipulates application for loop and line impedance measurement Z
L-PE and ZL-N as well as insulation
resistance measurement R
combination with the
– PROFITEST MTECH+, as of FW V03.04.00
– PROFITEST MXTRA, as of FW V03.04.00
– PROFITEST PRIME, as of FW V03.05.00
test instruments. Any other application (e.g.
voltage measurement or use in combination
with other test instruments) are not permissible.
Read the operating instructions carefully and
completely before placing your test instrument
into service. Follow all instructions contained
therein. Make sure that the operating instructions
are available to all users of the device.
Read the operating instructions for the respective
test instrument as well, in particular the sections
concerning the measurement of insulation, loop
and internal line resistance.
Tests may only be performed by a qualified electrician, or under the supervision and direction of a
qualified electrician. The user must be instructed
by a qualified electrician concerning performance
and evaluation of the test (see also training seminars listed at www.gossenmetrawatt.com).

PROFITESTREMOTE Safety Precautions
Observe the following safety precautions:
• The device may only be connected to electrical systems with a maximum of 230/
400 V which comply with applicable safety
regulations
(e.g. IEC 60346, VDE 0100) and are protected with a fuse or circuit breaker with a
maximum rating of 16 A.
• The test adapter may only be used for tests
described in the section entitled “Applications”.
• When using a test probe with coil cord:
Grip the tip of the test probe firmly, for
example if it has been inserted into a jack
socket. Tensioning at the coil cord may
otherwise cause the test probe to snap
back resulting in possible injury.
• Insulation resistance can only be measured at voltage-free systems.
• Do not touch the test probes during
measurement!
Fuse Replacement
All fuses for the test adapter’s neutral and
phase conductors are accessible from the
outside (see section 6.3). The fuses may
only be replaced when the instrument is voltage-free, i.e. the instrument must be disconnected from mains supply power and may
not be connected to a measuring circuit. The
fuse type must comply with the specifications in the technical data or the labeling on
the instrument (see section 5).
Opening the Device / Repairs
The test adapter may only be opened by
authorized, trained personnel in order to
ensure flawless operation and to assure that
the guarantee is not rendered null and void.
Even original replacement parts may only be
installed by authorized, trained personnel.
If it can be ascertained that the test adapter
has been opened by unauthorized personnel, no guarantee claims can be honored by
the manufacturer with regard to personal
safety, measuring accuracy, compliance
with applicable safety measures or any consequential damages.
The test adapter may not be used:
• If external damage is apparent, for example if parts which conduct dangerous
touch voltage are freely accessible, and
in the event of defective LEDs
•
With damaged connection and/or measurement cables, e.g. interrupted insulation or
kinked cable
• If it no longer functions flawlessly
• After extraordinary stressing due to transport
In such cases, the test adapter must be
removed from operation and secured against
unintentional use.

PROFITESTREMOTE Applications
2 Applications
Use of the test adapter eliminates bothersome replugging, and thus reversing of the
phases as well during measurement of RISO,
Z
L-PE and ZL-N.
The following measurements are supported:
L1-PE, L2-PE, L3-PE,
N-PE, L+N-PE,
L1-N, L2-N, L3-N,
L1-L2, L1-L3, L2-L3
The following test instruments are suitable
for use with the test adapter:
– PROFITEST MTECH+, as of FW V03.04.00
– PROFITEST MXTRA, as of FW V03.04.00
– PROFITEST PRIME, as of FW V03.05.00
Indication of Conductor Connections
The LEDs indicate conductor continuity
between the connected system and the test
instrument’s input:
– Red LED: Switch closed,
– Green LED: Switch open, no connection
The line circuit-breaker is opened and
closed via the test adapter controller at the
respective test instrument.
conductor continuity
Measuring Loop and Line Impedance Z
L-PE and
ZL-N
Loop impedance is the sum of all resistances within the distribution network and
the conductors in the branch circuit.
In order to be able to determine the effectiveness of residual current devices, loop
impedance Z
L-PE must be ascertained
between the phase conductor and the protective conductor. The same measuring procedure is used for line impedance Z
also the case for loop impedance Z
L-N as is
L-PE.
However, the current loop is completed via
neutral conductor N, rather than protective
conductor PE as is the case with loop
impedance measurement.
Observe the corresponding chapters in the
operating instructions of your test instrument
concerning correct measurement procedures.
Thanks to 4-wire measurement,
there’s no need to determine the test
adapter’s offset value.
Measuring Insulation Resistance
RISO in Electri-
cal Systems
In order to be able to detect faults in electrical systems which are caused by defective
insulation, insulation resistance must be
measured between each active conductor
and the protective earth conductor.
Observe the corresponding chapters in the
operating instructions of your test instrument
concerning correct measurement procedures.
Thanks to 4-wire measurement,
there’s no need to determine the test
adapter’s offset value.
