 Double Your Power.
A maintenance and calibration tool that will be at home in every instrumentation technician's tool box, the Fluke 787 ProcessMeter™ 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.
 Fluke Process Meters - ProcessMeter™ Model 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.
• 150V overload protection on mA, backed up by 440 mA 1000V
