A maintenance and calibration tool that will be at home in every instrumentation technician's tool box, the Fluke 787 ProcessMeterT combines a DMM and a Loop Calibrator in one rugged, handheld tool, for about what you would expect to pay for a loop calibrator alone. Based on the trusted Fluke 87 DMM, the 787 adds the ability to measure, source, and simulate dc loop current with 0.05% accuracy and 1 microamp resolution. The 787 offers: Simultaneous mA and % of scale readout on mA output, 25% Manual Step plus Auto Step and Auto Ramp on mA output, Clear LCD with backlight; 4,000 counts (30,000 counts for dc current), Min/Max/Average/Hold/Relative modes, Externally accessible battery for easy battery changes, 1000V overload protection on V, ohms, frequency, and 150V overload protection on mA, backed up by 440 mA 1000V fuse.
