Do not clean the instrument, its switches, or its terminals with contact cleaners, abrasives, lubricants,
solvents, acids/bases, or other such chemicals. Clean the instrument only with a clean dry lint-free
cloth or as instructed in this manual.
Not for critical applications
This instrument is not authorized for use in contact with the human body or for use as a component
in a life-support device or system.
Do not touch live circuits
Instrument covers must not be removed by operating personnel. Component replacement and
internal adjustments must be made by qualified service-trained maintenance personnel who are
aware of the hazards involved when the instrument's covers and shields are removed. Under certain
conditions, even with the power cord removed, dangerous voltages may exist when the covers are
removed. To avoid injuries, always disconnect the power cord from the instrument, disconnect all
other connections (for example, test leads, computer interface cables, etc.), discharge all circuits, and
verify there are no hazardous voltages present on any conductors by measurements with a properly-
operating voltage-sensing device before touching any internal parts. Verify the voltage-sensing device
is working properly before and after making the measurements by testing with known-operating
voltage sources and test for both
another person capable of rendering first aid and resuscitation is present.
Do not insert any object into an instrument's ventilation openings or other openings.
Hazardous voltages may be present in unexpected locations in circuitry being tested when a fault
condition in the circuit exists.
Fuse replacement
Fuse replacement must be done by qualified service-trained maintenance personnel who are aware
of the instrument's fuse requirements and safe replacement procedures. Disconnect the instrument
from the power line before replacing fuses. Replace fuses only with new fuses of the fuse types,
voltage ratings, and current ratings specified in this manual or on the back of the instrument. Failure
to do so may damage the instrument, lead to a safety hazard, or cause a fire. Failure to use the
