| | | Hantek CC-650 AC/DC CURRENT CLAMP | | INTRODUCTION When measuring the AC/DC Current with the Current Clamp, a multimeter or scope cn directly measure the current up to 650A, with a frequency up to 400HZ. In this method,there is no need to break a circuit od to affect the isolation to measure the current, The Current Clamp is not only available for the detection or monitor of the possibly existing creepage,but for thr measurement with little gap using its extended jaws,However, it is necessary to turn the zero adjustment knobs on the clamp until the multimeter or scope reads zero, AC/DC Current Clamp, 400Hz Bandwidth, 1mV/10mA, 650A
Feature
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.
Power circuit measurement and malfunction analysis; Motor drive of frequency converter (or other electronics) measurement; 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 electronics equipments measurement. APPLICATION PROCEDURE 1. When connected with any multi-meter whose input impedance is 10K ohms minimum, insert the black banana plug into the COM jack and the red banana plug into the V-Ω jack.When connected with a scope,connect the BNC connector of the clamp to a scope BNC connector. 2. Set the power switch form "Off" to "ON" position,that is to set the multimuter range to 1mV/100mA or1mV/1A. Then, the green LED will be lighting, indicatiing that the clamp is switched on.. 3.when the current is not greater than 20 ampere,please set the current clamp range to 1mV/100mV and set the multimeter range to 200mV AC or 200mV DC, which depends on the type of the current. 4. Before measuring the DC current, it is needed to turn the zero adjustment knobs on the clamp until the multimeter reads zero.That means pushing down the zero adjustment knobs on the clamp until the multimeter reads zero. Then let go hold od the zero adjustment knobs, When using a scope, set DC coupled mode to measure DC current. 5. Clamp the jaws around the current-carrying conductor and operate as above. When current clamp range is set to 1mV/100mA, the actual current value is one hundred times of the measured data whose unit is mA. Foe example,the measured dats is 10mA and The actual current of the current-carrying conductor is 10 x100=1000mA. When the current clamp range is set to 1mV/1A, the actual current of the current-carrying conductor is 5 x 1000=5000mA. APPLICATION NOTES 1. In the case of DC current ,the output is positive when the current flows from the upside to the underside of the clamp, The red banana plug is positive. 2. In the case of DC current measurement, the current clamp can not possibly zero properly.due to the hysteresis effect. To eliminate this, open and close the jaws several times and zero again.
