Oscilloscope current probe for applications in industrial and power environments. Analyze, measure and accurately display distorted current waveforms and harmonics.
Oscilloscope current probe for applications in industrial and power environments. Analyze, measure and accurately display distorted current waveforms and harmonics.
The Model JM861 is designed for oscilloscopes, waveform displaying instruments and other instruments able to benefit from its frequency response. The Model JM861 encompasses a special circuit and three ranges to maximize frequency response performance. Accurately measures AC current waveforms and has proportional mV output for direct readings on oscilloscopes. Three-position slide switch on the handle selects ranges. Large jaw window enables use on cables and bus bars.
