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 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. • CAT I 1000 V, CAT II 600 V 3 A perfect fit for many applications, 4 Patented split terminal jacks enable Clear and bright dual display shows data in 4-wire measurements with two leads graphic or numeric formats Input terminals are located on the front and Context sensitive soft function keys make it back of the meter to simplify connections easy to navigate through measurements and within a system instrument settings 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 available 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 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 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 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. USB port for flash memory devices (8846A) provides convenient data storage and transport Single button per function for ease of use 5 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 histogram, with the unique analyze mode. You won’t find graphical display capabilities like these on any other instrument in this class. 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.
