Description Hantek CC650 400Hz 650A Oscilloscope Multimeter AC DC Current Clamp with BNC ConnectorIt 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 650A with a frequency uo to 400Hz 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 400Hz Effective measurement range 20mA to 650A 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 circuiit measurement and malfunction analysis Motor drive of frequency converter or other electronics measurement Power electronics equipment measurement Specification Efficient Measure Range 1mV 100mA 100mA to 20A Multimeter Range is set to DC or rms AC 200mV1mV 1A 1A to 200A Multimeter Range is set to DC or rms AC 200mV 200A to 650A DC or rms AC 2VDC Current Accuracy 0 to 650A 3 reading 2A AC Current Accuracy 50Hz arrive at 400HzCaptured Conductor Size Max 30mmLow Battery Indicator Red LED LightingOperating Temperature 0°C to
