Fluke 789 ProcessMeter Digital Multimeter and Loop Calibrator by Fluke Corporation

The Fluke 789 ProcessMeter combines advanced troubleshooting capabilities with versatile measurement functions in a compact design, making it an essential tool for electricians and instrumentation professionals. Featuring a large, bright dual-display with adjustable backlighting, the 789 enables quick and clear readings in various lighting conditions. Its full-featured multimeter functions include frequency measurement up to 20 kHz, diode testing, continuity testing, and Min/Max/Average/Hold/Relative modes, providing comprehensive diagnostics for control systems. Additionally, the device integrates a built-in 24-volt loop supply, reducing the need for external power sources when testing transmitters and loops.

Designed for efficiency, the Fluke 789 offers the ability to source, measure, and simulate 4-20 mA signals, with a 1200-ohm drive capability on mA sourcing. Its adjustable span check and 0%, 25%, and 100% buttons facilitate rapid troubleshooting by toggling between different current scales, while the display can simultaneously show mA and percentage of scale readings for faster diagnosis. The device also features a selectable 250-ohm HART resistor, eliminating the need to carry additional resistors. Its manual step, auto ramp, and auto step modes provide flexible control over signal adjustments, with an accuracy of 0.1% for DC voltage and 0.05% for DC current.

Constructed with user convenience in mind, the Fluke 789 includes externally accessible fuse and batteries for easy replacement, and it supports wireless data logging with the optional Fluke Connect™ IR3000FC module. The device comes with a comprehensive package including alligator clips, test leads, batteries, and a quick reference guide, backed by a three-year limited warranty. Weighing approximately 1.34 pounds, the Fluke 789 ProcessMeter is a robust, reliable choice for efficient control loop troubleshooting and calibration, offering a combination of precision, safety, and wireless connectivity in a single instrument.
