The DM-860A is a full featured Industrial Digital Multimeter and the latest addition to the family. Features: • AC+DC True RMS, 50,000-count dual display for greater accuracy. 500,000 count available in DC voltage mode. • VFD (variable frequency drive) voltage and frequency functions for accurate readings on noisy drive waveforms. • Beep-Jack™ audible and visual input alert helps avoid blown fuses or damage to meter. • 41-segment analog bar graph makes it easy to view quick changes. • Record max, min, avg, and max-min and data hold. • Crest capture (peak hold) max and min readings. • Relative offset display mode makes monitoring relative measurement changes simple. • Performs resistance, conductance, frequency, duty cycle, temperature and capacitance measurements, plus diode and continuity tests. • Dual temperature measurement up to 1832°F/1000°C using type K thermocouples. • Autoranging for convenient operation and time savings. • Bright, backlit display is easy to read under any light condition. • Intelligent Auto Power Off conserves battery life but will not turn meter off during measurements. • Wide AC bandwidth — to 100 kHz for voltage and 20 kHz for current. • USB interface using optional DMSC-9U cable and software allows connection to a PC for extended measurement capability. • Accessories included: (1) 9 V battery, bead temperature probe (400°F/ 204°C max.), test leads, protective boot, carrying case.
