The deflected silicon chip then creates a voltage perpendicular to the path of the electron flow. While the current flows through the wire, the clamp meter senses the magnetic field within the air gap that contains the Hall Effect detector and forces a deflection on it. When the clamp surrounds the wire it creates a magnetic field according to Ampere’s Law the magnetic field is concentrated by the iron core contained in the clamp. When the current flows through the conductor, the clamp meter takes contactless readings using a semiconductor Hall Effect to measure the axial magnetic field generated in it. It can be used to troubleshoot electricity, but unlike the multimeter and other current measuring devices, it is more convenient and even safer to use because you don’t have to break the circuit before you get a reading ( Check clamp meters on ). So when your car or battery-powered device stops functioning properly, the necessary thing would be to perform a test on it, which you can carry out with a clamp meter.Ī clamp meter is a current measuring device that can also function as a multimeter. Vehicle and most home appliances powered by batteries run on direct current other DC sources are solar cells and thermocouples.
The flow of current could be direct or alternated, direct current is denoted as “DC,” and it differs from alternating current, in that it flows in a constant direction. Talking about electricity without mentioning current would be difficult, the current is the flow of electricity through a circuit or a conductor, and it is measured in ampere. Before we go into in-depth explanations on how you can measure DC amps with a clamp meter, we would begin by giving a summary of the DC amp and the clamp meter, so you have an understanding of how they relate.
