The Fluke 377FC and 378FC are the industry’s first smart true-rms clamp meters equipped with patented FieldSense™ non-contact voltage technology. Only one ground wire is required; clamp the jaw around conductors to read voltage and current simultaneously without touching live wires with test leads, fundamentally cutting high-voltage electric shock risks. Supplied with iFlex flexible current probe for AC current up to 2500 A, easy to fit tight cable trays and irregular busbars. Complete 3-phase measurement in 3 steps with auto calculation of phase-to-phase & phase-to-ground voltage and phase sequence. Bluetooth connects to Fluke Connect mobile APP for real-time sync, data storage and export, enabling paperless maintenance reports. The upgraded 378FC features exclusive PQ power quality screening to instantly detect harmonic and power factor distortion, quickly locating faults on grid supply or load equipment. A safe, high-efficiency testing tool for industrial power distribution, new energy and HVAC maintenance,
