1 Applications
The test instrument is used to test the electrical safety of monophase and 3-phase
electrical devices. The test instrument allows
for the measurement of protective conductor
resistance, insulation resistance and differential current and/or contact current in
accordance with DIN VDE 0404.
2 Safety Features and Precautions
The test instrument has been manufactured
and tested in accordance with the following
safety regulations:
IEC 61010-1 / DIN EN 61010-1 / VDE 0411-1,
IEC 61557-2/-4 / DIN EN 61557-2/-4 /
DIN VDE 0413-2/-4
When used for its intended purpose, the
safety of the user, the test instrument and
the device under test (electrical equipment
or electrical medical device) is assured.
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 instrument.
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
in the execution and evaluation of tests.
Safety Precautions for MINITEST 3P Master
The instrument is intended for connection
with a 3-phase system up to 32 A.
MINITEST 3P Master
customary CEE and earthing contact outlets via
the adapters included in the standard equipment.
can also be connected to all
The instrument may only be connected to the mains via the adapters
included in the standard equipment.
All mains sockets and/or test sockets
are connected in parallel:
Only one DUT at a time may therefore be
connected to a socket.

Observe the following safety precautions:
!
• MINITEST Master / Pro / Base:
The instrument may only be connected
to electrical supply systems with 230 V/
240 V which conform to the valid safety
regulations (e.g. IEC 60364, VDE 0100)
and are protected with a fuse or circuit
breaker with a maximum rating of 16 A.
• Measurements within electrical systems
are prohibited.
• Be prepared for the occurrence of
unexpected voltages at devices under
test (for example, capacitors may be
dangerously charged).
• Make certain that the measurement
cables are in flawless condition, e.g. no
damage to insulation, no cracks in
cables or plugs etc.
• Insulation Resistance Measurement R
Testing is conducted with up to 500 V.
Current limiting is utilized (I < 3.5 mA),
but if the terminals (L or N) are touched,
electrical shock may occur which could
result in consequential accidents.
• Differential Current Measurement I
Contact Current Measurement I
It is absolutely essential to assure that
the device under test is operated with
line voltage during performance of the
differential current and/or contact current
measurement. Exposed conductive
parts may conduct dangerous contact
voltage during testing, and may not
under any circumstances be touched
(MINITEST Master / Pro:
mains power is disconnected if leakage
current exceeds approx. 15 mA).
• The function test may only be performed
after the device under test has
successfully passed the safety test while
connected to the test socket!

Opening of Equipment / Repair
The equipment may be opened only by
authorized service personnel to ensure the
safe and correct operation of the equipment
and to keep the warranty valid.
Even original spare parts may be installed
only by authorized service personnel.
In case the equipment was opened by unauthorized personnel, no warranty regarding
personal safety, measurement accuracy,
conformity with applicable safety measures
or any consequential damage is granted by
the manufacturer.
The measuring and test instrument may not be used:
• if it demonstrates visible damage
• with damaged connector cables and
measuring cables
• if it no longer functions properly
• after extraordinary stresses due to transport
• MINITEST 3P Master: with other adapters
than those included in the standard
equipment.
In such cases, the instrument must be
removed from operation and secured
against unintentional use.
Meanings of Symbols on the Instrument
The symbols on the instrument have the
following meanings:
Warning concerning a point of
danger (attention: observe
documentation!)
Indicates EC conformity
The device may not be disposed
of with the trash. Further information regarding the WEEE mark
can be accessed on the Internet
