TR3031X series is the 1 universal oscilloscope current probe, compatible with more than 95% of oscilloscopes on the market, with a frequency response measurement range of 50mA to 100A (peak value) up to 5MHZ, and BNC output terminals. Connect an oscilloscope to accurately measure AC or DC current waveforms, with a selectable range on the handle panel; the current probe detects the current flowing through the conductor and converts it into a voltage that can be seen and measured on the oscilloscope. The current probe uses a hybrid technology including a Hall effect sensor (sensing DC current) and a current transformer (sensing AC current). The open design current probe is easy to connect and disconnect from the conductor, providing a DC to 5.5MHz measurement bandwidth.
Product Features
