Fluke FLUKE-378 Fc True Rms Clamp Meter 1000V Cat Iii Iv

Product Description

The FLUKE FLUKE-378 FC is a True RMS clamp-on meter rated for 1000 VAC and 1000 VDC measurements, designed for licensed electricians and instrumentation technicians working on commercial and industrial electrical systems. The meter measures voltage, current, capacitance, resistance, and power in a single handheld tool. It features a digital display with True RMS AC wave measurement, ensuring accurate readings on non-sinusoidal loads common in variable-frequency drive circuits and other distorted-waveform environments. The FLUKE-378 FC ships as a complete kit including the meter, an iFlex flexible current probe, silicone-insulated test leads, adjustable test probes, a grounding clip, and a magnetic hanging kit.

The FLUKE-378 FC is suited for residential service panels, commercial electrical distribution, and light industrial applications where CAT III and CAT IV safety ratings are required. The included iFlex flexible current probe allows access to conductors in tight or congested panels where a rigid jaw clamp cannot fit. The meter supports a temperature measurement range of -10 to 50 degrees C, making it useful for basic thermal checks during commissioning or troubleshooting. The magnetic hanging kit adds hands-free convenience during single-technician service calls.

Key Features

• True RMS AC measurement for accurate readings on distorted waveforms and VFD-driven loads
• Measures capacitance, current, resistance, voltage, and power from a single instrument
• Rated CAT III and CAT IV for use in high-energy electrical environments
• 1000 VAC and 1000 VDC maximum voltage measurement
• Includes iFlex flexible current probe for access in congested panel wiring
• Complies with IEC 61326-1 and CISPR 11 Group 1 Class B electromagnetic compatibility standards

Compatibility

Designed as a general-purpose True RMS clamp meter for use on single-phase and multi-phase low-voltage electrical systems rated up to 1000 volts, suitable wherever CAT III or CAT IV measurement category compliance is required.

Installation Notes

Installation and use of this meter should be performed by a qualified electrician or instrumentation technician familiar with NEC safety practices for live electrical measurement. Always verify the circuit voltage does not exceed the meter's 1000-volt rating before taking a measurement. De-energize and lock out circuits whenever possible before connecting test leads to terminals. Inspect test leads and probes for insulation damage before each use.
