Traditionally voltage has been measured by attaching test lead probes or alligator clips directly to electrical conductors, which requires metal-to-metal contact that brings with it the risk of arc flashes and potential harm to both the person doing the measuring and the equipment being measured. Fluke FieldSense™ technology offers a safer way to measure voltage by isolating the measurement tool from the voltage source under test, reducing the risk of electrical shock and arc flash. Through the principle of galvanic isolation, FieldSense™ allows electricians and technicians to measure voltage without exposing themselves to contact points with live voltage. Instead, FieldSense™ enabled test tools such as the Fluke FieldSense™ 377 FC and 378 FC Clamp Meters, sense the electrical field in the open fork/clamp and measure the voltage through the cable insulation.
Commercial and light industrial electricians can use FieldSense™ based devices for voltage and current measurements, verifying continuity values, and testing individual circuits.
