The Fluke 8845A and 8846A 6.5 digit precision
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 %, 10 A current range, and
a wide ohms range give you an unbeatable combination of measure-
ment capability.
You can also use the 8845A and 8846A to measure temperature,
capacitance, period, and frequency—the functions of a counter, capaci-
tance meter, and thermometer are built in for unparalleled versatil-
ity. Extend the meters’ utility even more with their graphical display
modes, including TrendplotTM paperless recorder mode, statistics and
histograms—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.
Exceed your expectations for performance and value
With 14 measurement functions, math and analysis modes, the 8845A/8846A will meet the needs of any test, research and development,
or service application.
View results in Histogram mode to reveal stability or noise problems
in analog circuits.
Use the built-in TrendPlot paperless chart recorder to graphically
identify the extent of drift and intermittent events in analog circuits.
Handle even the most demanding measurements with high
accuracy and 6.5 digit resolution.

A perfect fit for many applications, in a system or on the bench.
Clear and bright dual display shows data in
graphic or numeric formats
Input terminals are located on the front and
back of the meter to simplify connections
within a system
Single button per function for ease of use
Context sensitive soft function keys make it
easy to navigate through measurements and
instrument settings
Patented split terminal jacks enable
4-wire measurements with two leads
Easy to integrate into your automated test system
The 8845A and 8846A meters can be incorporated easily into your
automated test system. These meters emulate several legacy bench
DMMs, allowing them to be substituted easily into existing systems.
SCPI compatibility and drivers allow them to work with most avail-
able application and development languages.
Front and rear inputs let you easily make connections where it’s
most convenient, whether the meter is rack-mounted or used on a
bench. Multiple interfaces provide compatibility to existing and new
standards.
Reading rates are greater than 1000 readings per second giving
you the throughput you need for systems applications.
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 trending analysis. 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 simulta-
neously 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 out-of-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 mea-
surements you can make and tests you can perform with a single
instrument.
Perfect for benchtop research and development
Research and development applications demand measurement per-
formance 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.
USB port for flash memory devices (8846A)
provides convenient data storage and transport

FlukeView® Software and drivers add
PC power and application compatibility.
FlukeView Forms increases the power of your Fluke
tool by enabling you to document, store and analyze
individual readings or series of measurements, then
convert them into professional-looking documents.
Log live readings while connected to a PC or store,
display and share readings in interactive forms,
graphs and tables. Create customized, professional
looking documents that can be printed or emailed.
FlukeView Forms software includes easy-to-use
standard forms.
Instrument programming drivers, DLL files and
support information are included to get your test
system up and running as quickly as possible.
FlukeView® Forms Basic
The Fluke 8845A/8846A ship with a free copy of
FlukeView Basic. Transfer data points from your
meter to your PC and use the two standard, non-
customizable forms to display your readings in table
or graphical form. For a larger array of forms or to
use FlukeView® Forms Designer to customize your
forms, upgrade to FlukeView® Forms version 3.0
with FVF-UG.
Fluke 45 and Agilent 34401A emulation
The 8845A/8846A emulate operation and program-
ming commands of the Fluke 45 and Agilent 34401.
Emulation shortens the learning curve and makes
it easy to fit the 8845A or 8846A into existing test
systems.
Fluke support completes
the equation of value
Like all Fluke products, the 8845A/8846A 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 ser-
vice centers strategically located around the world.
Each offers a full range of support services.
Multiple connectors give you
maximum flexibility
Choose from several interfaces to connect the
8845A/8846A to a personal computer: serial,
IEEE-488, and Ethernet come standard on both
models. A USB device port is included on the 8846A
meter for convenient data transfer to and from
a PC via a portable USB storage device.
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. To reveal
signal quality issues like drift, intermittants and
stability, view data as a real time trend plot or histo-
gram, with the unique analyze mode. You won’t find
graphical display capabilities like these on any other
instrument in this class.
Perform 4-wire measurements
with only two leads
Patented split terminal jacks for the 2 x 4 ohms
function allow you to perform 4-wire measurements
using only two leads instead of four. A special test
lead accessory is available to enable you to establish
the connection. You get excellent resolution and
accuracy plus the convenience and ease of using
a single pair of leads.
With 6.5 digit performance, legacy DMM emulation and the latest interfaces, the 8845A/8846A
will easily integrate into any legacy or new test system.
