When the utility model is used, the movable iron core is opened by pressing the handle, and the conducting wire of the current to be measured is put into the jaw, and the iron core is closed after being released. The current through the wire equivalent transformer primary, secondary inductive current, current meter is connected to the secondary coil, so that the secondary coil current, form scale is good has returned to the current scale, which can indicate the value of measured current. A table is convenient to use, but the accuracy is not high.
Clamp meter is to measure the AC current meter, only AC can be used, when using single line wire clamp, clamp meter in the middle, according to the size of the current regulation of the current size of the gear, you can read the current readings.
