How to Use:
1. Multimeter (MA Level Current File)

It can directly view the current value after the transformer transformation ratio, the standard configuration is 2500:1.
2. Oscilloscope
For the measurement of direct current or alternating current, the indirect method is generally used.
Specific Method: first transform the amount of current into a proportional voltage amount, and then observe with an oscilloscope
General Test Method: Connect a non inductive resistor with Precision Machined and small resistance in series in the circuit under test, and then measure the voltage with an oscilloscope to measure the effective value of the voltage at both ends of the resistor, and then calculate the measured current value , Its calculation formula is 1=U/R. In the formula, the measured current value A; the effective value V of the voltage at both ends of the series resistance; R the resistance value of the series connected non inductive resistance Ω.
3. Other Instruments
It can be combined with self developed instruments and meters, and can be used as a current probe.
Clamp the live wire or null wire alone to measure the current of the line. (Note that 1 stick must be stuck)

Clamp the live wire and null wire together to measure the single phase leakage current. (Note that 2 sticks need to be stuck)
Clamp the ground wire to measure the leakage current of the ground wire of the electrical equipment. (Note that 1 stick must be stuck)
