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.
