Safety precautions
The insulation tester has been constructed and tested to
comply with IEC 61557 / EN 61557 / VDE 0413 und IEC
61010-1 / EN 61010-1 / VDE 0 411-1.
When properly used, the safety of both the user and the
tester is assured. It is not assured, however, if the tester is
misused or carelessly handled.
To maintain the safe and proper condition of the tester and to
ensure Its safe operation, it is absolutely necessary to carefully
and completely read these operating instructions before using the
tester. These instructions must be followed in all respects.
Repair and replacement of parts
When opening the tester, live parts may be exposed. The
tester must be disconnected from all voltage sources prior
to repair or replacement of parts. If a repair cannot be
avoided unless the tester is open and live, this must only be
performed by a qualified person who understands the dan-
ger involved.
Faults and extraordinary stress
When it must be assumed that safe operation is no longer
possible, take the tester out of service and secure it against
accidental use. It is assumed that safe operation is no
longer possible,
• when the tester shows obvious signs of damage,
• when the tester no longer functions correctly,
• after prolonged storage under adverse conditions,
• after severe transport stress.
Attention!
!
The fixed test leads have a double insulation in dif-
ferent colors. You can readily recognize damaged
leads by the light insulation on the inside.
The VDE Test Office has approved the use of the VDE-GS
mark (tested safety) for the insulation tester.
