Description

Technical Field

[0001] The utility model relates to the technical field of current testing clamps, in particular to a current testing clamp. Background Art

[0002] A current test clamp, also known as a clamp meter or current clamp, is a tool used to measure the current in a circuit, allowing the user to make measurements without interrupting the circuit. The current clamp clamps the wire and uses the principle of electromagnetic induction or the Hall effect to measure the current passing through the wire. For alternating current, the current clamp usually uses an electromagnetic current transformer to generate a current proportional to the alternating current through a coil, and then converts the electrical signal into a digital signal for display. For direct current or very small alternating currents, the current clamp may use a Hall effect sensor, which can detect changes in the magnetic field and convert it into an electrical signal.

[0003] The existing current test clamp does not have a data line storage function, which will cause the data line connector to be exposed, which may be affected by dust, moisture or other pollutants, resulting in degradation of the connector performance. Utility Model Content
