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 applica-
tion for loop and line impedance measure-
ment Z
L-PE and ZL-N as well as insulation
resistance measurement R
ISO exclusively in
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 permis-
sible.
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 elec-
trician, 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 semi-
nars listed at www.gossenmetrawatt.com).
