Fluke 287 Electronics Multimeter

Fluke Corporation has published a series of application notes to help electricians and electronics professionals do advanced electrical testing with their Fluke digital multimeters (DMMs).

The advanced Fluke 287 Electronics Multimeter has multiple features specifically designed for electronic technicians working in service applications, as well as those involved in the design and development of new electronic products. These special capabilities are explained in a Fluke application note, "The electronic technician’s Fluke 287 DMM," available on the Fluke web site.

For instance, the large ¼ VGA dot-matrix display on the Fluke 287 offers more flexibility in changing function displays, and provides more information at a glance. In the MIN MAX mode it’s large enough to show the current reading, the Min, Max, and Avg readings, along with their time stamps, elapsed time, and the start time and date for the recording session, all at once.

Other capabilities built into the Fluke 287 that electronic technicians will appreciate:

  • 100 kHz bandwidth with V ac and mV ac functions, and the ability to read voltage values expressed as dBV or dBm. This true-rms reading function is essential for evaluating the performance of servo loops and audio amplifiers.
  • Capacitance that reads to 100 mF, useful for the large capacitors used in electronic motor drives and power inverters.
  • AC + dc true-rms voltage and current.  Volts or amps readings can be made showing individual ac and dc values in a dual display, or the two values may be combined to display the true-rms signal present.
  • Temperature.  The mV dc menu offers the ability to convert the meter to a thermometer.  Using the recording function to log temperature over time means the test technician can evaluate electronic system cooling over a wide range of conditions for a day or more.
  • Basics.  This new meter excels in the basics too, beginning with its 50,000 count resolution. Its 50 mV range enables users to read voltages down to 1 V.  Basic dc accuracy is 0.025 %, while basic true-rms ac readings are accurate to 0.3 %.

The Fluke application note explaining the special features of the Fluke 287, entitled "The electronic technician’s Fluke 287 DMM," is available with other Fluke case studies and notes on the Fluke application notes web page for DMMs.  For more information on the Fluke 287 Electronics Multimeter, or to find the location of the nearest distributor, visit
