Clamp ammeter is referred to as clamp meter. Its working part is mainly composed of an electromagnetic ammeter and a penetrating current transformer. The core of the through-type current transformer is made into a movable opening and is in the shape of a clamp, hence the name of a clamp-type ammeter. It is a portable instrument that can directly measure the circuit AC current without disconnecting the circuit. It is very convenient to use in electrical maintenance and has a wide range of applications.

  • Clamp meter is an instrument integrating current transformer and ammeter. It is an important branch of digital multimeter. Its working principle is the same as that of current measurement by current transformer.
  • 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 current is measured can pass through the open gap of the core without cutting, and the core is closed when the wrench is released. The wire of the circuit under test that passes through the core becomes the primary coil of the current transformer, and the current is induced in the secondary coil by passing the current. So that the ammeter connected to the secondary coil will have an indication —— measuring the current of the circuit under test.
  • The clamp meter was originally used to measure AC current, but now the multimeter has functions that can also measure AC and DC voltage, current, capacitance, diode, triode, resistance, temperature, frequency and so on.
  • Autoranging clamp multimeter measures AC currents, AC/DC voltage, resistance, and also provides diode and continuity tests.
  • The clamp measures the AC current in a conductor without interrupting the circuit.
  • Data hold and LCD display, easy and clear to read.
  • Low battery indicator function.
  • Overload protection.
  • The clamp measures the AC current in a conductor without interrupting the circuit.
  • Electromagnetic current meter and bushing type current mutual inductor. Straight through current transformer core made of movable opening, and a clamp on ammeter, named. The utility model relates to a portable instrument which can directly measure the AC current of a circuit without disconnecting the circuit.
  • Fit for schools, factories, families, and amateur wireless lovers.
