Data sheet


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.
