Use clamp meter?

Answer:

The use of AC clamp meter measurement can only clamp into a wire, can not clamp into two or more wires.
The use of AC clamp meter measurement before estimating the measured current size, to select the appropriate range. If the magnitude of the current to be measured cannot be estimated, the maximum range of one gear shall be used for rough measurement, and then the appropriate range shall be changed according to the actual current to make more accurate measurements
The measurement of general AC clamp meter suitable for low voltage circuit, using the measured voltage circuit voltage should not exceed a specified old clamp meter. No special accessories AC clamp meter, it is prohibited to use directly in high voltage circuit.
In order to improve the accuracy of measurement, the wire must be placed in the center of the jaw. A core not near the transformer and motor shell and other electrical components, so as to avoid the influence of external magnetic field.
