The Fluke 80i-1000s is an AC current probe that extends the current measurement capabilities of oscilloscopes and other voltage-measuring instruments through non-intrusive clamp-on measurement. It measures AC current from 100 mA to 1000 A rms continuously, with instantaneous peak capability to 2000 A, making it suitable for industrial and power environments where accurate distorted waveforms and harmonics characterization is required.
