Background

The split core ammeter is formed by combining a current transformer and an ammeter. The iron core of the current transformer can be opened when the wrench is tightened; the lead through which the current to be measured passes can pass through the open notch of the iron core without being cut off, and the iron core is closed after the wrench is released. The circuit conductor under test passing through the core becomes the primary coil of the current transformer, where the passage of current induces a current in the secondary coil. Therefore, the ammeter connected with the secondary coil can measure the current of the line to be measured.

The clamp-on ammeter at the present stage does not have a storage function of measurement data, if the current data of a line to be measured needs to be called, an operator needs to record the measurement time and the current data after each measurement, and the method is very inefficient and difficult to meet the condition of calling a large amount of current data.
