The invention relates to an ammeter, in particular to an ammeter comprising a plurality of separate components, in particular the monitoring unit and the input and output unit are separate smart current meters arranged separately from the ammeter body.

Current Meter

In many electrician work sites, it is often necessary to measure the load current for a certain circuit in order to understand the power consumption and usage of transformers, branch lines, and electrical appliances. Therefore, ammeters are necessary equipment and are the most common and convenient on the market. The ammeter used is a clamp-type ammeter. It does not need to shut down the circuit before the meter can be connected for measurement. It can measure the current of the wire through the principle of electromagnetic induction. Its structure includes the housing of the ammeter. An openable jaw, an electromagnetic transformer disposed inside the jaw, and a data display, the jaw is located at the upper part of the housing, the operation switch of the jaw opening and closing is placed on the side of the housing, and the data display is fixed at the lower part of the housing .

Because the clamp ammeter is easy to use, it is also standard equipment for electrician work. However, whether it is a clamp-type ammeter or a conventional ammeter, the components such as the electromagnetic transformer and the data display are both the main body of the ammeter, but such a product structure cannot be measured.
