Background
A clamp-on ammeter (also known as a current clamp) is a tool for measuring current. The non-contact measuring principle is adopted, and direct current or alternating current can be measured without breaking a circuit. Clamp-on ammeters generally consist of a ferromagnetic ring with a magnetic core, which ring can completely or partially enclose the wire to be measured. When current passes through the wire under test, a magnetic field is generated in the ferromagnetic ring. The clamp-on ammeter determines the magnitude of the current by measuring the strength of this magnetic field. When the clamp ammeter is used, the clamp ammeter is only required to be opened and the ferromagnetic ring is placed around a wire to be measured. The magnitude of the current can be known by reading the value displayed on the meter. Some clamp-on ammeters also have data recording and storage functions that can record changes in current over a period of time.
