1 Safety Precautions
General
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 GOSSEN METRAWATT GMBH.
The phase sequence indicator has been manufactured and
tested in accordance with safety regulations IEC 61 010-1 /
DIN EN 61010-1 / VDE 0411-1.
When used for its intended purpose, safety of the operator,
as well as that of the instrument, is assured. Their safety is
however not guaranteed if the instrument is used improperly or handled carelessly.
In order to maintain flawless technical safety conditions,
and to assure safe use, it is imperative that you read the
operating instructions thoroughly and carefully before placing
your instrument into service, and that you follow all instructions
contained therein.
Repair and Parts Replacement
When the instrument is opened, voltage conducting parts
may be exposed. The instrument must be disconnected
from the measuring circuit or the device under test before
maintenance or the replacement of parts.

GB
The following safety precautions must be observed:
• The instrument may only be operated by persons who
are capable of recognizing contact hazards and taking
the appropriate safety precautions. Contact hazards
exist anywhere, where voltages of greater than 30 V
r.m.s. may occur.
• Avoid working alone when taking measurements
which involve contact hazards. Be certain that a
second person is present.
• Make certain that the measurement cables are in
flawless condition, and that they do not suffer from
damage to the conductors or their insulation. This
applies to test probes and alligator clips as well.
• No measurements may be made with this instrument
in electrical circuits with corona discharge
(high-voltage).
• Measurements under moist ambient conditions are not
permitted, nor are their results reliable.
• Use the recommended batteries.
• The instrument is not a voltmeter in the usual sense of
the word: it only reads out voltages within the indicated
ranges.
Errors 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 further use.
Safe operation can no longer be relied upon,
• if the instrument demonstrates visible damage,
• if the instrument no longer functions.
