The Instek GCP-020 40Hz-10KHz/20A Clamp Current Probe for GDS 3000 Series makes clamp measurement safe and easy. To perform current waveform measurement, just clamp the jaw around the conductor-under-test and connect its lead to the BNC input of an oscilloscope. Breaking the circuit and connecting an ammeter in series is no longer necessary.

Using the combination of a Hall-effect sensor and an AC current transformer, GCP-020 provides accurate measurement from 40Hz to 10kHz. The dual measurement range spans 100mA-20A and 500mA-200A. In addition to oscilloscopes, the GCP-020 can also be connected to multimeters and data loggers.
