AC/DC Max. 20 kHz 20mA to 650A DC Current Clamp Meter Multimeter with BNC Connector

1. Model Name: CC650;
2. AC/DC Current Clamp, 400Hz Bandwidth, 1mV/10mA, 650A;
3. It is a transducer which allows your multimeter to measure current data and enable your oscilloscope to measure the current waveforms;
4. Its current transducer is composed by permalloy and hall element, which linearly transform the AC or DC current to AC or DC current voltage;
5. with its BNC connected to oscilloscope, it will help to observe the current waveforms; If connected to a multimeter by banana type connector, it will help to obtain the current data.

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 then zero again.
3. When the current clamp range is set to 1mV/100mA, the actual current value is one hundred times of the measured data whose unit is mA.

1. AC/DC frequency range: Up to 400Hz
2. Effective Measurement Range: 20mA to 650A DC;
3. Output: BNC type connector.

Application Procedure

1. When connected with any multi-meter or 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 multimeter range to 1mV/100mA or 1mV/1A. Then, the green LED will be lighting, indicating that the clamp is switched on;

3. When the current is not greater than 20 ampere ,please set the current clamp range to 1mV/100mA and set the multi-meter range to 200mV AC or 200 mV 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 of 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.
