1 Safety Features and Precautions
The tester is manufactured and tested in accordance with the following standards:
IEC/EN 61010-1/VDE 0411-1 Safety regulations for electrical measuring, control,
regulating and laboratory devices – general requirements
and
DIN VDE 0404-1/-2: Testing and measuring equipment for checking the electric safety
of electric devices; Part 1: general requirements, and Part 2:
Testing equipment for tests after repair, change or in case of repeat tests
When used for its intended purpose, the safety of the user, the test instrument and the device
under test (electrical equipment) is assured.
Read the operating instructions carefully and completely before placing your test instrument into ser-
vice, and follow all instructions contained therein. Make sure that the operating instructions are avail-
able to all users of the instrument.
The tests may only be conducted under the supervision of a qualified electrician. The user must be in-
structed by a qualified electrician in the performance and evaluation of the test.
Observe the following safety precautions:
• 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 pro-
tected with a fuse or circuit breaker with a maximum rating of 16 A.
• No measurements within electrical systems are allowed.
• Be prepared for the occurrence of unexpected voltages at devices under test. For exam-
ple, capacitors may be dangerously charged.
• Make certain that connector cables are not damaged, e.g. damaged insulation, interruptions etc.
Attention!
!
Devices under test may only be connected to the mains outlet after they have
successfully completed safety testing in accordance with DIN VDE 0701-702!
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 per-
sonal safety, measurement accuracy, conformity with applicable safety measures or any con-
sequential damage is granted by the manufacturer.
Repair, Parts Replacement and Balancing
Voltage conducting parts may be exposed when the device is opened. The device must be
disconnected from all sources of voltage before repair, replacement of parts or balancing. If
repair or balancing of an open, live device cannot be avoided, this may only be performed by
trained personnel who are familiar with the dangers involved.
Errors and Extraordinary Strains
If it may be assumed that the device can no longer be operated safely, it must be removed
from service and secured against unintentional use. Safe use can no longer be relied upon,
• if the device demonstrates visible damage,
• if the device no longer functions,
• after lengthy periods of storage under unfavorable conditions.
