The clamp ammeter is commonly referred to as a clamp meter. Its working components mainly consist of an electromagnetic ammeter and a core-type current transformer. The core-type current transformer has a movable opening in its iron core, which is shaped like a clamp, hence the name clamp ammeter. It is a portable instrument that can measure alternating current in circuits without disconnecting them. It is very convenient for electrical maintenance and widely used.
The clamp meter is an instrument that combines a current transformer and an ammeter. It is an important branch of digital multimeters, and its working principle is the same as that of a current transformer for measuring current. The clamp meter is composed of a current transformer and an ammeter. The core of the current transformer opens when the wrench is tightened; the wire through which the measured current passes can pass through the opening in the open core without being cut off. When the wrench is released, the core closes. The circuit wire passing through the core becomes the primary coil of the current transformer, and the current passing through it induces a current in the secondary coil. Thus, the ammeter connected to the secondary coil provides an indication—measuring the current of the circuit under test.
The clamp meter was originally used to measure alternating current, but now it has all the functions found in a multimeter—it can measure AC and DC voltage, current, capacitance, diodes, triodes, resistance, temperature, frequency, and more.
