CC-800 AC/DC CURRENT PROBE

OPERATOR’S

MANUAL

INTRODUCTION

The multimeter/oscilloscope can directly measure the DC current of no more than 800A
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 of f the insulating layer.

The current probe is not only suitable for the dete ction or monitoring of possibl e 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 os ci ll oscope, connect the BNC p lu g of t he current probe to
the BNC terminal of the oscillosco pe.

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 t he t ype 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 butto n.

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 exa m pl e, 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 oscillosco pe is mu ltiplied by 1000 to o bt ain the actua l current value, and
the unit of the current value is mA. For exa m pl e, if the value measured by the current
multimeter is 5mV, the actual current value of the current-carrying conductor under

2

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 altern ating c urrent is ex press ed by t he ef fectiv e 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 cur r ent 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 adjus t ment knob to approach the zer o 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 forbi dden to measure bare conductor s
and conductors with crac ked or frayed insulation.

Accuracy

System accuracy: the sum of the accur acy of t he current pr obe and t he accur acy of the
digital multimeter or oscilloscope
For example, if the condu ct or being measured carries a curr ent of 1A, set the current
probe to 10mV/A and the output signal is 10mV. Ass um ing that the accuracy is 1.5%,
the maximum output v alue is 10.15mV and the minimum is 9.85 m V.
If the digital multimeter connected to the current probe is in the 200mV range, if it s
accuracy is 0.5%, the maximu m v alu e displayed by the digita l mu ltimeter is 10.20mV
and the minimum is 9.80m V. (10.15mV× (1+0.5%) =10.20mV, 9.85mV× (1-0.5%)
=9.80mV)
