The Fluke 289 CAL is a high-performance industrial logging multimeter engineered for complex troubleshooting and predictive maintenance across electronics, plant automation, power distribution, and electro-mechanical equipment. It delivers True-RMS AC and DC measurements with exceptional resolution and captures transient events as fast as 250 μs. The integrated TrendCapture feature graphically displays logged data directly on the multimeter’s large backlit dot-matrix display, enabling rapid anomaly detection without PC connection.
