The Fluke Y8100 DC/AC Current Probe is a clamp-on probe that is used with a voltmeter, multimeter, or oscilloscope to read dc, ac, or composite (ac on dc) current measurements. The jaws on the Y8100 are designed to clamp around conductors up to % inch in diameter. The pistol shape allows safe, easy, one-hand operation when making current measurements. APPLICATIONS The Y8100 can be used to measure any of the following: . Ground currents ac and dc. Power supply ripple. . Current distribution in multiple systems. Current balance in two wires ac and dc. . Current in audio distribution systems (using 440 to 1000 Hz signals). Starting currents without introducing impedance (imparts negligible inductance in the mH range). Transformer currents . Battery currents . Current distribution and perform ripple current tests in plating operations. . Current transients (dc to l kHz) when used with an oscilloscope.
