multimeter for bench or automated test system applications

8808A 5.5 digit multimeter: Versatile

multimeter for manufacturing, development

and service applications

With 14 measurement functions,
math and analysis modes, the
8845A/8846A will meet the
needs of any test, research and
development, or service application.

Exceed your

expectations for

performance and value

The Fluke 8845A and
8846A 6.5 digit precision

CAT II 600 V multimeters have
the precision and versatility to
handle your most demanding
measurements, on the bench
or in a system. These meters
are both high performance
and feature rich, yet also
remarkably easy to use.

These digital multimeters
perform the functions you
would expect to see in a
multifunction DMM, including
measuring volts, ohms, and
amps. Basic V dc accuracy
of up to 0.0024 %, 100 uA
to 10 A current ranges, and
a wide ohms range from
10 Ohms to 1 GOhm give you
an unbeatable combination of
measurement capability.

You can also use the 8845A
and 8846A to measure tem­perature, capacitance, period,
and frequency—the functions
of a counter, capacitance
meter, and thermometer
are built in for unparalleled
versatility.

Extend the meters’ utility
even more with their graph­ical display modes, including
Trendplot
mode, statistics and histo­grams—Log readings to a USB
flash drive and easily transfer
them over to a PC with the
8846A USB device host
port —features you won’t find
on other multimeters.

Of course, these meters are
also durable and depend­able, features you expect from
any Fluke meter. This unique
combination of features and
performance makes the
8845A and 8846A an unbeat­able value for a wide variety
of applications, including
manufacturing test, research
and development, and service.

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.
