SUMMARY
The
following
general
safety
precautions
must
be
observed
during
all
phases
of
operation,
service,
and
repair
of
this
instrument.
Failure
to
comply
with
these
precautions
or
with
specific
warnings
elsewhere
in
this
manual
violates
safety
standards
of
design,
manufacture,
and
intended
use
of
the
instrument.
Hewlett-Packard
Company
assumes
no
liability
for
the
customer's
failure
to
comply
with
these
requirements.
GROUND
THE
INSTRUMENT
To
minimize
shock
hazard,
the
instrument
chassis
and
cabinet
must
be
connected

DO
NOT
OPERATE
IN
AN
EXPLOSIVE
ATMOSPHERE
Do
not
operate
the
instrument
in
the
presence
of
flammable
gases
or
fumes.
Operation
of
any
electrical
instrument
in
such
an
environment
constitutes
a
definite
safety
hazard.
KEEP
AWAY
FROM
LIVE
CIRCUITS
Operating
personnel
must
not
remove
instrument
covers.
Component
replacement
and
internal
adjustments
must
be
made
by
qualified
maintenance
personnel.
Under
certain
conditions,
dangerous
voltages
may
ex-
ist
even
with
the
instrument
switched
off.
To
avoid
injuries,
always
disconnect
input
voltages
and
discharge
circuits
before
touching
them.
DO
NOT
SERVICE
OR
ADJUST
ALONE
Do
not
attempt
internal
service
or
adjustment
unless
another
person,
capable
of
rendering
first
aid
and
resuscitation,
is
present.
DO
NOT
SUBSTITUTE
PARTS
OR
MODIFY
INSTRUMENT
Because
of
the
danger
of
introducing
additional
hazards,
do
not
install
substitute
parts
or
perform
any
unauthorized
modification
to
the
instrument.
Return
the
instrument
to
a
Hewlett-Packard
Sales
and
Ser-
vice
Office
for
service
and
repair
to
ensure
that
safety
features
are
maintained.
DO
NOT
OPERATE
A
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
a
Hewlett-Packard
Sales
and
Service

ensure
that
safety
features

INSTRUMENT
DESCRIPTION
1-6.
The
HP
3457A
is
a
versatile
high
precision
digital
multimeter
which
measures
ac
or
de
volts,
ac
or
de
current,
actde
volts
or
current,
resistance,
frequency
and
period.
It
measures
voltages
up
to
300
Vac
or
300
Vde
with
high
de
resolution
and
accuracy.
The
instrument
is
designed
for
both
bench
and
system
use.
Program
and
reading
storage
are
included
to
allow
high
speed
measurement
applications
with
reading
rates
of
greater-than
1000
read-
ings
per
second.
Provision
has
been
made
for
optional
assemblies
such
as
a
general
purpose
scanner
or
multiplexer
assembly.

INSTRUMENTS
COVERED
BY
THIS
MANUAL
1-10,
Instruments
covered
by
this
manual
are
identified
by
a
serial
number
prefix
listed
on
the
title
page.
Hewlett-Packard
uses
a
two
part
serial
number
in
the
form
xxxxayyyyy,
where
xxxx
is
the
serial
prefix,
a
is
the
country
of
origin
(A=USA)
and
yryyy
is
the
serial
suffix.
The
serial
number
prefix
identifies
a
series
of
identical
instruments.
The
serial
number
suffix
is
assigned
sequentially
and
is
unique
to
each
instrument,
1-11.
If
the
serial
number
prefix
of
your
instrument
is
greater
than
the
one
listed
on
the
title
page,
a
yellow
Manual
Changes
supplement
will
explain
how
to
adapt
this
manual
to
your
instrument.
1-12.
If
the
serial
number
prefix
of
your
instrument
is
lower
than
the
one
listed
on
the
title
page,
information
contained
in
Section
VII
(Manual
Backdating)
will
explain
how
to
adapt
this
