Fluke 369 FC | Large-Jaw True-RMS AC Leakage Current Clamp Meter

Leakage-current testing becomes difficult when multiple conductors or larger cables cannot fit through a standard leakage clamp. The Fluke 369 FC True-RMS Leakage Current Clamp Meter provides the same high-resolution diagnostic capability as the 368 FC but adds a larger 61 mm jaw for demanding conductor arrangements.

The meter detects leakage currents with resolution down to 1 µA and measures AC current up to 60 A. A selectable 40–70 Hz filter helps isolate fundamental power-frequency leakage, while wideband operation to 1 kHz allows broader investigation when required. True-RMS measurement improves accuracy on complex waveforms, and Fluke Connect enables readings to be logged, documented and compared over time. Its larger jaw makes the 369 FC particularly suitable for grouped conductors, larger feeders and installations where access would limit the smaller 368 FC.

Large-Jaw Leakage Meter Selection Guide

Choose the 369 FC when you need the 61 mm jaw for larger cables or multiple conductors. If a 40 mm jaw fits the installation comfortably, the 368 FC offers the same core leakage-current measurement concept in a smaller format.

Market Relevance

For Pakistani industrial plants, large commercial buildings, data centres, utilities and facility-maintenance teams, the Fluke 369 FC provides a practical way to investigate leakage without shutting equipment down. Buy the Fluke 369 FC from Kamadi Pakistan for high-resolution leakage-current testing on larger electrical installations.

Professional Tip: Use the narrow 40–70 Hz filter first when investigating mains-frequency leakage; switch to wideband only when higher-frequency leakage from electronic equipment or drives is relevant.
