ELECTRICAL HAZARD
•
These guidelines must be followed to ensure that the safety
mechanisms in this instrument will operate properly. This
instrument must be plugged into an AC only electric outlet
as listed in Section 3.1, Specifications. The power cord of
the instrument is equipped with a three-pronged grounding
plug for your protection against electrical shock hazards. It
must be plugged directly into a properly grounded three-
prong receptacle. The receptacle must be installed in
accordance with local codes and ordinances or adapter
plug. DO NOT use an extension cord. Consult a qualified
electrician. Always inspect the power cord before use for
any damage to the insulation due to contact with hot
surfaces, cuts or abrasions.
•
The instrument is equipped with operator accessible fuses.
If a fuse blows, it may be due to a power surge or failure of a
component. Replace the fuse once. If the fuse blows a
second time, it is likely caused by failure of a component
part. If this occurs, contact a Hart Scientific Authorized
Service Center. Always replace the fuse with one of the
same rating, voltage, and type. Never replace the fuse with
one of a higher current rating.
•
Always replace the power cord with an approved cord of the
correct rating and type. If you have questions, contact an
Authorized Service Center (see Section 1.3).
