It is a transducer which allows your multimeter to measure current data and enable your oscilloscope to measure the current waveforms. When measuring AC/DC Current with the Current Clamp， a multimeter or scope can directly measure the current up to 65A， with a frequency uo to 20KHz. In this method， there is no need to break a circuit or to affect the isolation to measure the current.

Features:
AC/DC frequency range: up to 20KHz.
Effective measurement range: 20mA to 65A DC.
Allows your multimeter to measure current data and enable your oscilloscope to measure the current waveforms.
Its current transducer is composed by permalloy and hall element， which linearly transform the AC or DC current to AC or DC current voltage.
If connect to an oscilloscope by BNC type connector， you're able to observe the current waveforms.

Application:
Power circuit measurement and malfunction analysis; 
Motor drive of frequency converter (or other electronics) measurement; 
Power electronics equipment measurement.
