Multimeter Voltmeter Digital Clamp Meter Current Clamp AC DC Ammeter Multi-function Diode Fire Wire Tester resistance voltage Meter MT-87
The clamp ammeter is referred to as the clamp meter. Its working part is mainly composed of an electromagnetic ammeter and a through-core current transformer. The core of the through-core current transformer is made into a movable opening and is in the shape of a clamp, hence the name clamp ammeter. It is a portable instrument that can directly measure the AC current of the circuit without disconnecting the circuit. It is very convenient to use in electrical maintenance and has a wide range of applications.
The clamp meter is an instrument that integrates a current transformer and an ammeter. It is an important branch of a digital multimeter. Its working principle is the same as that of a current transformer for measuring current. 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 measured current passes can pass through the opening of the core without cutting off, and the core is closed when the wrench is released. The wire of the circuit under test passing through the core becomes the primary coil of the current transformer, in which the passing current induces current in the secondary coil. So that the ammeter connected to the secondary coil has an indication-----measure the current of the circuit under test.
The clamp meter was originally used to measure AC current, but now it also has the functions of a multimeter, which can measure AC and DC voltage, current, capacitance, diodes, transistors, resistance, temperature, frequency, and so on.
