Precision digital Multimeters

By Plant Engineering Staff November 15, 2006


Fluke 8845A and 8846A precision digital multimeters feature 6.5 digit resolution, graphical display modes, multifunction measurement capability and 14 measurement functions. The dual display shows data in graphic or numeric formats.These high-accuracy meters are designed for bench or systems applications including manufacturing test, research and development, and service.

The 14 measurement functions extend the capability of a standard DMM with wider ranges and features to measure temperature, capacitance, period and frequency.The 2 x 4 ohms function uses patented split-terminal jacks that allow users to perform 4-wire measurements using only two leads instead of four. The meters measure volts dc with an accuracy of up to 0.0024%; have a voltage range of 100 mV to 1000 V with up to 100-nV resolution, current range of 100

The meters also feature a large, bright dual display that enables users to measure two different parameters of the same signal from one test connection and view the results in graphic or numeric format.With graphical display modes including TrendPlot paperless chart recording, statistics and histograms, users can analyze data in real time for efficient troubleshooting of signal quality issues such as drift, intermittants and instability.

Designed for easy integration in automated test systems, the meters emulate several legacy bench DMMs, and feature input terminals on both the front and rear of the instrument to simplify connections.Both meters are equipped with serial, IEEE-488 and Ethernet interfaces, and provide multiple drivers to help ensure compatibility with existing or new standards. The Fluke 8846A has a wider feature set, including higher throughput and accuracy, the ability to measure temperature and capacitance and a USB device port, which allows users to save measurement results to a USB memory drive for later analysis on a personal computer.
