Check the listing for details. Hantek CC650 AC/DC Current Clamp. Condition: New. Listed at 84.99 USD. Description: Hantek CC650 with batteries Features: 1. AC/DC frequency range: Up to 400Hz Effective Measurement Range: 20mA to 650A DC It is a transducer which 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. And if connect to an oscilloscope by BNC type connector, you're able to observe the current waveforms; If connect to a multimeter by banana type connector, you can obtain the current data. Application: Power circuit measurement and malfunction analysis; Motor drive of frequency converter (or other electronics) measurement; Power electronics equipments measurement. Specification: Conventional characteristic measurable conductor size: the largest diameter of 30 mmLow power indicator: red led lights flashingWorking temperature range: 0C to 50C, 70% R.H.Storage temperature range: - 20 C ~ + 70 C , 80% R.H.Electrical characteristics precision: (23 ± 5C , 70% R.H. maximum) Dc current: 0 to 650A , +/- (3% reading + 2A )Alternating current (50 hz to 400 hz) :0 to 500A , +/-(3% reading + 2A )500A to 600A , +/- (6% reading + 2A )600A to 650A , +/-(8% reading + 2A )Load impedance: 10 k Ω (typical value) Output scale: 0 to 650 mv (AC/DC) corresponding to 0 to 650A (1 mV / 1A file); 0 to 1.6 V (AC/DC) corresponding to 0 to 160 a (1 mV / 100 mA file); Battery life: a typical carbon zinc batteries for 100 hours.
