1 Safety Precautions
This instrument fulfills the requirements of the applicable European and
national EC guidelines. We confirm this with the CE marking. The relevant
declaration of conformity can be obtained from GMC-I Messtechnik
GmbH.
The METRISO 1000A insulation tester has been manufactured and tested
in accordance with the following standards:
IEC 61010-1/EN 61010-1/VDE 0411-1,
DIN VDE 0413 part 1:2007 and part 4:2007,
IEC 61557-2/EN 61557-2/VDE 0413-2
IEC 61557-4/EN 61557-4/VDE 0413-4
In order to maintain flawless technical safety conditions and to assure safe
use, it is imperative that you read the operating instructions carefully and
thoroughly before placing your instrument into service, and that you follow
all points contained therein.
Repair and Parts Replacement
Voltage conducting parts may be exposed when the instrument is
opened. The instrument must be disconnected from all sources of voltage
before repair or replacement of parts. If the repair of an open, live instrument cannot be avoided, this may only be performed by trained personnel
who are familiar with the dangers involved.
Malfunctions and Extraordinary Strains
If it may be assumed that the instrument can no longer be operated
safely, it must be removed from service and secured against unintentional
use. Safe operation can no longer be relied upon:
• If the instrument demonstrates visible damage
• If the instrument no longer functions
• After lengthy periods of storage under unfavorable conditions
• After excessive strain during transport
The permanently attached measurement cables are double insulated with insulation materials of two different colors. Exposure of
the light colored inner insulation is an early indicator of excessive
cable wear.
