1-A. SAFETY CONSIDERATIONS
General
This instrument has been designed and tested
according to IEC Publication 348, "Safety
Requirements for Electronic Measuring Appa-
ratus," and has been supplied in safe cond~tion.
This is a Safety Class I instrument.
Operation
BEFORE APPLYING POWER, make sure the
instrument's ac input is set for the available
ac line voltage,
that the correct fuse is installed,
and that all normal safety precautions have
been taken.
Service
Although the instrument has been designed in
Manual change supplements are revised as often as necessary to keep manuals as current and accurate as possible.
Hewlett-Packard recommends that you periodically request the latest edition of this supplement. Free copies are available
from all HP offices. When requesting copies quote the manual identification information from your supplement. or the model
number and print date from the title page of the manual.

ERRATA (Cont'd)
accordance with international safety standards, the
information, cautions, and warnings in this manual
must be followed to ensure safe operation and to
keep the instrument safe. Service and adjustments
should be performed only by qualified service
personnel.
Adjustment or repair of the opened instrument
with the ac power connected should be avoided
as
much as possible and, when inevitable, should be
performed only by a skilled person who knows
the hazard involved.
Capacitors inside the instrument may still be
charged even though the instrument has been
disconnected from its source of supply.
Make
sure only fuses of the required current rat-
ing
and type (normal blow, time delay, etc.)
are used for replacement. Do not use repaired
fuses or short circuit the fuse holders.
Whenever it is likely that the protection has been
impaired, make the instrument inoperative and
secure it against any unintended operation.
r WARNING 1
If this instrument is to be energized through an
autotransformer (for voltage reduction), make sure
the common terminal is connected to the earthed
pole of the power source.
BEFORE SWITCHING ON THE INSTRUMENT,
the protective earth terminals of the instrument
must be connected to the protective conductor of
the mains power cord. The mains plug shall only
be inserted in a socket outlet provided with pro-
tective earth contact. The protection must not be

negated by using an extension cord (power cable)
without a protective grounding conductor.
Any interruption of the protective (grounding)
conductor, inside or outside the instrument, or
disconnection of the protective earth terminal is
likely
to make this instrument dangerous. Inten-
tional interruption of the earth ground is prohibited.
Servicing this instrument often requires that you
work with the instrument's protective covers re-
moved and with ac power connected. Be very care-
ful; the energy at many points in the instrument
may, if contacted, cause personal injury.
With
the ac power cable connected, the ac line
voltage is
present at the terminals of the power line
module and at the LINE power switch. Be very
careful. Bodily contact with this voltage can be
fatal.
BEFORE SWITCHING ON THIS INSTRUMENT,
make sure instrument's ac input is set to the
voltage of the ac power source.
BEFORE SWITCHING ON THIS INSTRUMENT,
make sure that all devices connected to the instru-
ment are connected to the protective earth ground.
BEFORE SWITCHING ON THIS INSTRUMENT,
make sure the line power (mains) plug is connected
to a three-conductor line power outlet that has a
protective (earth) ground. (Grounding one con-
ductor of a two-conductor outlet is not sufficient.
BEFORE SWITCHING ON THIS INSTRUMENT,
make sure the ac line fuse is of the required
current rating and type (normal-blow, time-delay,
etc.).
