Product Usage Instructions

Application Procedure

1. When connecting with a multimeter, insert the GND terminal of the BNC/banana-KJJ adapter into the COM terminal of the multimeter and the other terminal into the V- terminal.
2. For oscilloscope connection, plug the BNC plug of the current probe into the BNC terminal of the oscilloscope.
3. Set the power switch to the required range for measuring current (10mV/A or 1mV/A).
4. Ensure the green power indicator lights up for normal operation.
5. Select appropriate ranges on the multimeter based on the current being measured.
6. Perform zero adjustment by rotating the knob until the reading is close to zero.

Application Notes

• Output is positive when DC current flows from positive to negative terminal of the current probe.
• If zero point is not reached due to hysteresis effect, open and close jaws several times before readjusting.

Application Safety

1. Conductor voltage must be less than 300V DC or 240V rms AC .
2. Avoid measuring bare conductors or those with damaged insulation to prevent harm.

FAQ

• Q: What is the maximum current this current probe can measure?
  A: The CC-650 AC/DC current probe can measure up to 650A for DC current and 500A for AC current.

• Q: How do I adjust the zero point on the current probe?
  A: To adjust the zero point, rotate the zero adjustment knob until the reading on the multimeter or oscilloscope is close to zero.

INTRODUCTION

The multimeter/oscilloscope can directly measure the DC current of no more than 650A and the AC current of no more than 500A through the AC/DC current probe, and the measurement frequency is up to 5KHz. When measuring current with this current probe, there is no need to destroy the current loop or peel off the insulating layer.
The current probe is not only suitable for the detection or monitoring of possible leakage in the circuit, but also the extended jaw can be measured in a small gap. It should be noted that when measuring DC current, it is necessary to adjust the zero point by operating the zero adjustment knob.

APPLICATION PROCEDURE

1. When connecting with a multimeter, insert the GND terminal of the BNC/banana-KJJ adapter into the COM terminal of the multimeter, and insert the other terminal of the adapter into the V-Ω terminal. Please note that the input impedance of the multimeter used should be at least 10K ohms.
   When connecting with the oscilloscope, connect the BNC plug of the current probe to the BNC terminal of the oscilloscope.

2. Set the power switch from the “OFF” to the range required to measure the current, that is to say, push the switch slider to 10mV/A or 1mV/A range. When the current probe is powered normally, the green power indicator will light up.

3. When the measured current is not greater than 20 amperes, please set the current probe to the 10mV/A range, and select the AC 200mV or DC 200mV range on the multimeter according to the type of current being measured.

4. When measuring current, it is necessary to perform zero adjustment before measuring. That is to say, rotate the zero adjustment knob of the current probe until the reading on the multimeter is close to zero. When connecting an oscilloscope to measure DC current, set DC coupling. Before measuring, rotate the zero adjustment button of the current probe until the oscilloscope’s glow line returns to the reference position, and then release the zero adjustment button.

5. When the 10mV/A range of the current probe is selected, the data measured by a multimeter or oscilloscope (in mV) multiplied by 100 is the actual current value, and the unit of the current value is mA. For example, if the value measured by the current multimeter is 10mV, the actual current value of the current-carrying conductor under test is 10×100=1000mA.
   When the 1mV/A range of the current probe is selected, the data measured by a multimeter or oscilloscope is multiplied by 1000 to obtain the actual current value, and the unit of the current value is mA. For example, if the value measured by the current multimeter is 5mV, the actual current value of the current-carrying conductor under test is 5×1000=5000mA.
   When connecting an oscilloscope to measure AC current, you can use the measurement function of the oscilloscope to measure the peak-to-peak value and effective value of the AC current. For details, please refer to the operating manual of the corresponding oscilloscope. According to the range of the current probe, the peak-to-peak value and effective value of the alternating current are obtained according to the corresponding relationship between the above voltage and current. Usually the magnitude of the alternating current is expressed by the effective value. It is recommended that the acquisition mode of the oscilloscope be set to average mode.

APPLICATION NOTES

1. When measuring DC current, the output is positive when the DC current flows from the positive terminal to the negative terminal of the current probe.
2. When performing DC current measurement, the current probe may not reach the correct zero point due to the hysteresis effect. In order to eliminate this effect, you need to open and close the jaws of the current probe normally several times, and then adjust the zero adjustment knob to approach the zero point.

APPLICATION SAFETY

1. The voltage of the conductor measured by the current probe must be less than 300V DC or 240V rms AC.
2. In order to avoid harm to the human body, it is forbidden to measure bare conductors and conductors with cracked or frayed insulation.

Accuracy

System accuracy: The accuracy of the current probe and the accuracy of the digital multimeter or oscilloscope.
For example, if the conductor being measured carries a current of 1A, set the current probe to 10mV/A and the output signal is 10mV. Assuming that the accuracy is 1.5%, the maximum output value is 10.15mV and the minimum is 9.85mV. If the digital multimeter connected to the current probe is in the 200mV range, if its accuracy is 0.5%, the maximum value displayed by the digital multimeter is 10.20mV and the minimum is 9.80mV. (10.15mV× (1+0.5%) =10.20mV, 9.85mV× (1-0.5%) =9.80mV)
