The Fluke 789 ProcessMeter is a robust, all-in-one tool that supercharges troubleshooting for instrumentation pros, blending a full-featured loop calibrator with a CAT III 1000 V/CAT IV 600 V digital multimeter. It measures, sources, and simulates 4-20 mA signals with pinpoint 0.05% DC current accuracy, while its built-in 24 V loop power supply frees you from lugging extra gear for offline transmitter tests.
The true-RMS multimeter tackles AC/DC voltage, current, resistance, frequency up to 20 kHz, diode tests, and continuity, with a 1200-ohm drive capability for mA sourcing. A selectable 250-ohm HART resistor cuts setup hassle, and the large dual display shows mA and percent scale side-by-side for quick controller checks. With manual and auto step/ramp modes plus SpanCheck for instant 4-20 mA toggling, testing is a snap.
Fluke Connect (via optional IR3000FC module) lets you log and share data wirelessly, streamlining maintenance. Powered by four AA batteries for 140 hours of typical use, and backed by a three-year warranty, this rugged meter is a technician’s dream for tackling control loops with precision and ease.
