HP 3468A - Chapter II: Using The 3468 A; Introduction to 3468 A Operation; Operating Characteristics Overview; Detailed Operating Instructions

Introaguc
The
-hp-
Model
3468A
Digital
Multimeter
is
a
very
powerful
bench
instrument
equally
at
home
in
the
lab
or
production
areas.
In
the
first
chapter
you
saw
the
very
basic
features
of
the
3468A;
in
this
chapter
you
will
learn
to
use
those
features to solve your measurement
needs. The chapter starts with a short table
of
Operating
Characteristics.
Following
this
is
detailed
operating
information
ar-
ranged alphabetically
by subject. This information
in this chapter presents the
most
comprehensive
description
of
the
multimeter’s
functions.
Whether
you
use
your 3468A as a stand alone bench instrument
or coupled with a computer
or
handheld
calculator
for
a
measurement
system,
the
information
in
this
chapter
will
prove invaluable.
The Operating Characteristics of the 3468A are detailed in Table 2-1. This table is
an
abbreviated
set
of
specifications.
You
will
probably
find
that
this
table
answers
most
of
your
questions
about
the
capabilities
of
the
multimeter
without
poring
over
several
pages
of
specifications.
The
complete
Table
of
Specifications
for
the
3468A is given in Chapter V.
Operating Instructions
The goal of this chapter is to provide easy to find answers to the vast majority of
questions you may have about using your 3468A. To this end, this chapter is
divided into 11 major subject headings. Each subject presents the most com-
prehensive information about a particular feature or function of the 3468A. At the
end of most subjects will be a short list of HP-IL remote programming commands
that pertain to that subject.
