Fluke 369 FC True RMS Leakage Current Clamp Meter, 61 mm

The Fluke 369 FC True RMS Leakage Current Clamp Meter is a precision instrument designed to detect, document, and analyze leakage currents in electrical systems without taking equipment offline. It delivers True RMS readings across complex, non-sinusoidal waveforms and integrates Fluke Connect wireless connectivity for real-time data streaming to smartphones and tablets.

Technical Specifications

This meter measures alternating current across six ranges: 3 mA, 30 mA, 300 mA, 3 A, 30 A, and 60 A, with maximum resolution of 1 µA (0.001 mA). The frequency range spans 40 Hz to 1 kHz with selectable 50/60 Hz filters to suppress external noise. Crest factor rating of 3 handles transient-rich waveforms. True RMS circuitry ensures valid readings on distorted AC signals. The 61 mm jaw diameter accommodates standard conductor sizes. Fully shielded jaw geometry minimizes electromagnetic interference while capturing very small leakage signals. Display features backlit LCD with Max/Min/Average data logging and hold function. Forward-facing LED worklight illuminates dark cabinet interiors.
