KT87N Clamp Meter
A clamp ammeter is also known as a clamp meter. In the clamp ammeter, the meter converter and the ammeter are set in a table. It is an important branch of digital multimeters, and their current transformers and their working principles are the same. The instrument is mainly composed of an electromagnetic current meter and a sleeve type current transformer. The through-current transformer core is clamped by a movable opening and an ammeter.
The KT87N Clamp Meter is a new portable instrument that measures the AC current of a circuit without breaking the circuit. When the wrench is pressed, the core of the current transformer can be opened, and the wire through the current can be cut through the opening of the core without being cut. The circuit conductor to be tested passing through the core becomes the primary coil of the current transformer, and a current is induced in the two coils by the current. Therefore, an ammeter connected to the two coils can be used to indicate the current of the measuring line.
