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
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-
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.
With 14 measurement functions, math and analysis modes, the 8845A/8846A will meet the needs of any test, research and development,
or service application.
A perfect fit for many applications, in a system or on the bench.
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
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
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
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.
