The Fluke 187 Digital Multimeter utilises dual displays of a 50,000-count primary display for high resolution measurement readings along with a 5000 count secondary display. It also features a 51 segment bar graph analog display, options for true RMS AC, dual AC and DC or AC+DC displays, 100kHz AC bandwidth, dBm and dBV impedance references, duty cycle/pulse width, 250 µS fast MIN MAX, a beeper for continuity/open testing and a two level backlight. An IEC 61010 rating of Cat III to 1000V and Cat IV to 600V along with a rugged outer casing allows it to be used in many work environments.
