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 DC
and AC voltages.
Do not attempt any service or adjustment unless another person
capable of rendering first aid and resuscitation is present.
General Safety

other openings.
This instrument is not authorized for use in contact with the human
