The main advantage of the current probe is that it can measure current without disconnecting the power line. Based on the Hall effect, it can measure both DC and AC. Typical applications of current probes are system power measurement, power factor measurement, and switching machine impact current waveform measurements. The main drawback of the current probe is that its small current measurement capability is limited by the bottom noise of the oscilloscope, so the small current measurement capability is limited. Generally less than 10mA of current is difficult to measure.
