Technical content

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.
