        Simultaneous voltage and current

        measurements without metallic contact

            luke’s T6 instrument with FieldSense technology enables AC current, AC voltage and
            frequency measurements to be made on one device at the same time, in real-time without
       Fthe need for electrical contact. The T6 is the first handheld test tool using this new patent-
        pending technology.

        Safer way to test voltage
        FieldSense technology eliminates the need for metal-to-metal contact with test leads or alligator
        clips, offering a superior level of operator safety. FieldSense takes a measurement of voltage
        without voltage flowing through the meter. Instead, the Fluke instrument senses an electrical field
        in the open fork to make the measurement.

        How FieldSense works
        FieldSense technology is truly a breakthrough in how voltage is measured. While the technology
        in the T5 detects a magnetic field to derive an AC current measurement, the new technology
        detects an electrical field. Fluke Research and Development teams first developed the open-fork
        voltage sensing technology, which involves transducing and calculating a known signal to derive
        measurements for the source voltage.                                      applications include measurement of loads
