4. Instructions
1、Connect the BNC of the current probe to the oscilloscope (or other instruments), and connect
the USB cable to power the current probe;
2、Select the appropriate range on the probe according to current range, the corresponding
button light will turn Green;
3、Adjust the oscilloscope settings: input impedance 1MΩ; select probe to Current or display as A；
Set attenuation factor for corresponding channel，range 100A（0.01V/A） set to 100X， range 10A
（0.1V/A）set to 10X；
4、Press Automatic zero adjustment button to realize zero adjustment of the probe，after success，
the buzzer “beep” one time；if “beep” three times，indicating that the zero adjustment has failed；
Manual zero adjustment is also possible；the external magnetic field may have a slight influence
on the DC zero position of the probe，do not move it in a large range after the zero adjustment is
completed;
5、Open the jaws to clamp the conductor under test according to the direction indicated by the
clamp head. Note: If the measured current flows in the opposite direction to the clamp head, the
output will be negative;
6、Adjust the oscilloscope to get the best waveform;
Note: When the current exceeds the range, the buzzer will beep for a long time and the button
light will flash.
