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 measured by 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 cutting, and the core is closed when the wrench is released. The circuit lead to be tested that passes through the core becomes the primary coil of the current transformer, in which current is induced in the secondary coil by the current. Therefore, the current meter connected to the secondary coil has an indication-----measures the current of the line under test.
The clamp meter can be changed to different ranges by the shift switch. However, it is not allowed to operate with power when dialing. Clamp meters are generally not very accurate, usually 2.5 to 5. For ease of use, there are also different range of transfer switches for measuring different levels of current and measuring voltage.
The clamp meter was originally used to measure AC current, but now the multimeter has its own functions, which can measure AC and DC voltage, current, capacitance, diode, transistor, resistance, temperature, frequency and so on.
The clamp ammeter can measure the DC current of the PV and the AC current of the inverter. It is important to note that some clamp-type ammeters do not have a DC function, and the jaws should be tightly closed and cannot be charged.
So the question is, what brand of clamp-type ammeter is easier to use? The following are the top ten brands of the clamp-type ammeter recommended by Xiaobian, I hope to help you.
