General Safety Information
This is a Safety Class I instrument (provided with a protective earthing
ground, incorporated in the power cord). The mains plug shall only be
inserted in a socket outlet provided with a protective earth contact. Any
interruption of the protective conductor inside or outside of the instrument
is likely to damage the meter. Intentional interruption is prohibited.
WARNING
• Do not operate the instrument in an explosive atmosphere or in the
presence of flammable gasses or fumes.
• Do not use repaired fuses or short-circuited fuseholders: For
continued protection against fire, replace the line fuse(s) only with
fuse(s) of the same voltage and current rating and type.
• Do not perform procedures involving cover or shield removal unless
you are qualified to do so: Operating personnel must not remove the
meter covers or shields. Procedures involving the removal of covers
and shields are for use by service-trained personnel only.
• Do not service or adjust alone: Under certain conditions, dangerous
voltages may exist even with the instrument switched off. To avoid
electrical shock, service personnel must not attempt internal service
or adjustment unless another person, capable of rendering first aid
and resuscitation, is present.
• Do not operate damaged instrument: Whenever it is possible that the
safety protection features built into this instrument have been
impaired, either through physical damage, excessive moisture, or
any other reason, REMOVE POWER and do not use the instrument
until safe operation can be verified by service-trained personnel. If
necessary, return the instrument to an Agilent Technologies Sales
and Service Office for service and repair to ensure the safety
features are maintained.
• Do not substitute parts or modify the instrument: Because of the
danger of introducing additional hazards, do not install substitute
parts or perform any unauthorized modification to the instrument.
