Next, slide the fork around the ac conductor. You can create a capacitive path to ground by first firmly inserting both test leads into the storage dock on the back of the tester, then placing your finger firmly on the ground touch point on the back of the battery cover. FieldSense technology does require a capacitive path to earth ground which, with the T6 electrical tester, can be made in one of two ways. There is no direct electrical contact with live voltage so there’s much less potential for electrical shock or arc flash. Fluke FieldSense technology allows you to measure ac voltage, current, and frequency through the cable’s insulation by sliding the fork of the tester over the conductor. You had to either attach probes or alligator clips to the conductor, which immediately put you at risk of spark or arc flash. In the past, measuring voltage has required metal-to-metal contact.

Here are the top five ways this non-contact voltage measurement technology can help you work safer:ġ - No metal-to-metal contact when measuring ac voltage Commercial and light industrial electricians can use FieldSense-based devices for voltage and current measurements, verifying continuity values, and testing individual circuits. Instead, a FieldSense-enabled test tool such as the Fluke T6-1000 Electrical Tester senses the electrical field in the open fork and measures the voltage through the cable insulation. Through the principle of galvanic isolation, FieldSense allows electricians and technicians to measure voltage without exposing themselves to contact points with live voltage. This reduces the risk of electrical shock and arc flash. This requires metal-to-metal contact that brings with it the risk of arc flash and potential harm to both the person doing the measuring and the equipment being measured.įluke FieldSense technology offers a safer way to measure voltage by isolating the measurement tool from the voltage source under test. Traditionally voltage has been measured by attaching test lead probes or alligator clips directly to electrical conductors. The first goal of any electrician or technician who works around live voltage is to go home safe.
