The Fluke 289-NIST True RMS Industrial Data Logging Multimeter is a field instrument engineered for complex troubleshooting across electronics, plant automation, power distribution, and electro-mechanical systems. It combines advanced data logging with real-time measurement capabilities, enabling technicians to capture transients, trend equipment behavior, and diagnose faults without requiring a PC for initial analysis. The device features a large 50,000-count 1/4 VGA backlit display, True RMS measurement for non-linear loads, and NIST-traceable calibration certification.
