ST201 Digital Clamp Multimeter
The clamp meter is a meter that combines a current transformer and an ammeter. It is an important branch of a digital multimeter. Its working principle is the same as that of a current transformer. The clamp meter is a combination of a current transformer and an ammeter. The core of the current transformer can be opened when the wrench is tightened; the wire through which the current is measured can pass through the opening of the core without being cut off, and the core is closed when the wrench is released. The circuit lead wire that passes through the core becomes the primary coil of the current transformer, and when the current passes, the current is induced in the secondary coil. Therefore, the current meter connected to the secondary coil has an indication-----measures the current of the line under test.
Some tips：zero the data before measuring. Select the appropriate range, first select the large, then select the small range or look at the nameplate value to estimate. When measuring, the wire to be tested should be placed in the center of the jaws and the jaws should be closed tightly to reduce the error. After the measurement is completed, turn the transfer switch to the maximum range.
