Introduction - AEMC 6609 User Manual

• This instrument complies with safety standard IEC 61010 - 1, Ed
2 of February 2001.
• For your own safety, and to prevent any damage to your instru-
ment, you must follow the instructions given in this manual.
• This instrument can be used on CAT III electrical circuits not
exceeding 600V with respect to earth. It must be used indoors,
in an environment not exceeding pollution level 2, at an altitude
of not more than 2000m. The instrument can therefore be used
in complete safety on 400V three-phase networks in an industrial
environment.
• For safety reasons, you must use only measurement leads having
a voltage rating and category at least equal to those of the instru-
ment and compliant with standard IEC 61010-031.
• Do not use if the cover of the battery compartment is missing or if
the housing is damaged or not correctly closed.
• Do not place your fingers near unused terminals.
• If the instrument is used other than as specified in this manual,
the protection provided by the instrument may be impaired.
• Do not use this instrument if it seems to be damaged.
• Check the integrity of the insulation of the leads and of the hous-
ing. Replace damaged leads.
• Be prudent when working in the presence of voltages exceeding
70V or 33Vrms and 46.7Vpp; such voltages can cause a risk of
dc
electrocution. The use of individual protections is recommended
in some cases.
• Always keep your hands behind the physical guards of the probe
tips or alligator clips.
• Always disconnect all leads from the measurement and from the
instrument before opening the housing.
