HP 3468A - Chapter I: Meet The 3468 A; Introduction to the 3468 A Multimeter; How to Use This Manual

Introduction
Your
new
3468A
is
a
fully
programmable
HP-IL
digital
multimeter.
HP-IL
(Hewlett-
Packard
Interface
Loop)
is
a
serial
interface
allowing
the
-hp-
Model
41C/CV
family
of
calculators
or
desktop
computers
such
as
the
-hp-
Model
85
to
control
your
3468A.
In
an
automatic
test
or
on
the
bench,
the
3468A
offers
3
1/2
to
5
1/2
digit
resolution
for
measuring
dc
volts,
true
RMS
ac
volts,
2-
and
4-
wire
ohms,
and
de
and
RMS
ac
current.
The
3468A
offers
dc
voltage
performance
from
Ipvolt
sensitivity
up
to
300
volts
(full
scale),
true
RMS
ac
voltage
capability
up
to
300
kHz,
and
resistance
measurements
from
1
mQ
sensitivity
to
30MQ
(full
scale).
Its
dc
and
true
RMS
ac
current
measuring
capability
is
from
10A
sensitivity
up
to
3A.
The
optional
battery
pack
provides
up
to
5
hours
of
continuous
portable
operation.
By
selecting
the
number
of
digits
displayed
and
using
the
autozero
feature,
the
3468A allows you flexibility
in measurement
speed and accuracy.
Up to 31
readings
per
second
can
be
made
with
the
3468A
in
the
3
1/2
digit
mode.
The
fast
autorange
feature
of
the
3468A
allows
fast
bench
measurements
over
a
wide
dynamic range.
The
alphanumeric
Liquid
Crystal
Display
(LCD)
gives
you
measurement
units
as
part
of
the
reading
for
easy-to-read,
unambiguous
answers.
The
HP-IL
talk,
listen,
remote,
and
SRQ
status
information
is
also
available
with
LCD
annunciators.
The
SRQ
button
can
be
used
to
flag
or
interrupt
your
calculator
from
the
front
panel
of
the 3468A.
Furthermore, to lower your cost of ownership, the 3468A is calibrated elec-
tronically, either manually from the front panel or remotely in an automatic calibra-
tion
system.
There
are
no
internal
adjustments
and
the
calibration
of
all
functions
is
done
without
the
removal
of
covers.
The
self-test
function
verifies
most
of
the
internal
circuitry
of
the
3468A
indicating
proper
operation
of
the
multimeter.
How to Use This Manual
This Operators Manual has been designed with you the operator in mind; to serve
as a complete reference document for using the 3468A as a solution to your
measurement needs. It covers both bench use and remote programming.
Maintenance procedures, such as installation, are placed later in the manual
Chapter V. If, however, you have just received your 3468A you may want to read
that information. A separate service manual for the 3468A contains the informa-
tion on calibration, performance testing, and service.
