1. Summary
CPL2000A/4000A is a unique instrument that combines an current probe for oscilloscope with a clamp ammeter。CPL2000A/4000A is able to directly display the RMS current value without connecting any devices, and also able to measure the waveform by connecting to an oscilloscope.Its unique sensor design achieves twice the current measurement capability (4000ARMS) compared to similar products in the field, while ensuring excellent in accuracy. The display accuracy of the clamp ammeter function is up to 4 digit and the instrument contains our unique battery and USB dual power supply in the field.
