A perfect fit for many

applications, in a

system or on the bench

Dual display and
versatile graphical
capabilities

The 8845A/8846A feature
a unique dual display that
allows you to measure two
different parameters of the
same signal from one test
connection. Looking at dual
interrelated parameters like
voltage and current simulta­neously can reveal conditions
that might go unnoticed
otherwise, greatly simplifying
test and troubleshooting.

Versatile solutions
for advanced test
applications

These meters let you take
test and troubleshooting to a
new level. Set up the 8845A
or 8846A to take measure­ments over a period of time
and display them graphically
on the DMM’s screen, for real
time analysis. To reveal signal
quality issues like drift, inter­mittants and stability, view
data as a real time trend plot
or histogram, with the unique
analyze mode. You won’t find
graphical display capabilities
like these on any other instru­ment in this class.

Graphical trending analysis
can highlight drift and signal
fluctuations, as well as inter­mittent errors that can’t be
seen on a numerical display.

Using the graphical display,
the 8845A and 8846A can
simultaneously display a his­togram and multiple statistical
values such as mean, min,
max and standard deviation
calculated using real time
measurements. Analyzing a
measured values distribu­tion over time can highlight
potential reoccurring out­of-tolerance problems. The
ability to make dual simul­taneous measurements and
display them in graphic or
numeric format adds new
tools to the test system and
design engineer’s toolbox of
tricks for solving or validating
analog circuits.

Save measurement results
to USB memory and transfer
the data to a PC for detailed
analysis. Or use the Ethernet
connection to transport data
over a network.

Extended current and
ohms ranges and additional
capabilities such as tempera­ture and capacitance increase
the variety of measurements
you can make and tests you
can perform with a single
instrument.

Perfect for bench­top research and
development

Research and development
applications demand mea­surement performance and
flexibility. The 8845A and
8846A meet these needs,
with excellent performance
in all measurement func­tions. It’s easy to use and
adapts easily to almost any
benchtop application.

Fluke 45 and Agilent
34401A emulation

The 8845A/8846A emulate
programming commands
of the Fluke 45 and
Agilent 34401A. Emula­tion shortens the learning
curve and makes it easy
to fit the 8845A or 8846A
into existing test systems.

Perform 4-wire
measurements with
only two leads

Patented split terminal jacks
for the 2x4-wire ohms func­tion allow you to perform
4-wire measurements using
only two leads instead of
four. Today’s surface mount
components make it difficult
to make connections. The
task becomes even more
difficult when you need to
use a 4-wire technique for
accurate low ohms mea­surements. The Fluke test
lead accessory combines the
four wires into two test lead
pairs, making it easy for you
to establish connections.
You get excellent resolution
and accuracy, plus the con­venience and ease of using
a single pair of leads.

Patented split terminal jacks enable
4-wire measurements with two leads.

Input terminals are located on the
front and back of the meter to simplify
connections within a system.

Fluke support
completes the
equation of value

Like all Fluke products, the
8845A/8846A and 8808A
are built to provide years
of dependable service.
However, if you do need cal­ibration or repairs, you can
turn to our global network
of direct and representative
service centers strategically
located around the world.
Each offers a full range of
support services.

Making measurements

is as simple as

pushing a button

The Fluke 8808A 5.5 digit
multimeter has a broad

range of functions, measuring
volts, ohms and amps with a
basic V dc accuracy of 0.01 %.
It is remarkably easy to use,
even by unskilled operators,
because it makes the mea­surements you perform most
often extremely easy and fast
to do.

Six setup buttons on the
8808A front panel operate
like a car radio’s station pre­sets. Simply set up the meter
for a common measurement,
then press shift followed by
a setup button (S1 to S6) to
save the setup. Now each
time you perform that mea­surement, you simply press
the appropriate setup key. It’s
that easy!

The setup buttons eliminate
the need to follow complex
work instruction sheets.
Operators no longer need to
press multiple buttons to set
up a measurement function
and range, test limits, or enter
other paramters to make a
measurement.

Eliminate production
mistakes

The Fluke 8808A 5.5 digit
multimeter dependably
performs the most common
measurements required by
today’s applications. Whether
you are performing func­tional tests or making critical
measurements on test points,
using the limit compare mode
with pass/fail indicators
eliminates production mis­takes, especially those where
results are “on the edge.”

The 8808A display has
built-in enunciators that
clearly show the operator
whether a test passes or fails.
The pass/fail indicators take
the guesswork out of testing:
the result is either within
limits or it’s out!

The 8808A can

measure small

leakage currents

with a resolution

of up to 100 nA,

without loading the

circuit under test.

Improve quality

and efficiency in

manufacturing test, R&D

or service applications

Manufacturing test, R&D,
development and service
applications demand perfor­mance and flexibility from a
bench meter. This Fluke
8808A makes measurements
that stand up to any scrutiny.
It delivers a wide variety of
measurement functions,
including volts, ohms, and
amps, plus frequency—all
at superior accuracy and

resolution.

Measure two
parameters at once

The 8808A features a unique
dual display that allows you
to measure two different
parameters of the same signal
from one test connection.
Looking at dual interrelated
parameters like voltage and
current simultaneously can
reveal conditions that might
go unnoticed otherwise,
greatly simplifying test and
troubleshooting.

Measure sensitive
leakage current

Using a typical multimeter to
perform a sensitive low cur­rent measurement of less than
100 mA can load the circuit
under test while the measure­ment is made. This makes it
difficult, if not impossible, to
perform tasks such as deter­mining the leakage current
on a battery-powered device
while it is powered down. The
Fluke 8808A is the only multi­meter in its class to use a high
impedance input technique
to perform this type of critical
leakage current measure­ment. In this special mode,
the 8808A can measure small
currents with a resolution of
up to 100 nA, without loading
the circuit under test.

Fluke quality is built in

Fluke is known around the
world for its rugged, reliable,
and accurate multimeters.
With our experience, design
standards and quality assur­ance processes, we have
designed a multimeter that
will stand up to any scrutiny
of its specifications. In fact, a
Fluke meter typically per­forms better than specified.

All of our efforts are
designed to ensure that you
can make an accurate mea­surement—repeatedly, and
with confidence.
