Fluke 8845A/8846A

Digital Multimeters

Extended Speciﬁcations

The Fluke 8845A and 8846A 6.5 digit precision multime-

ters 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, with

performance that exceeds expec-

tations. Basic V dc accuracy of

up to 0.0024 %, 10 A current

range, and a wide ohms range

from 10 W to 1 GW with up

to 10 μW resolution give you

an unbeatable combination of

measurement capability.

You can also use the 8845A

and 8846A to measure tempera-

ture, 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™

paperless recorder mode, statis-

tics 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 combi-

nation of features and perfor-

mance makes the 8845A and

8846A an unbeatable value for

a wide variety of applications,

including manufacturing test,

research and development, and

service.
