A digital clamp meter A multimeter with built-in clamp. Pushing the large button at the bottom opens the lower jaw of the clamp, allowing the clamp to be placed around a conductor. An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, tong tester, or colloquially as an amp clamp.
Every inline series-connected ammeter, including a multimeter in a current range, has a certain resistance. Most multimeters inherently measure voltage, and pass a current to be measured through a shunt resistance, measuring the voltage developed across it. The voltage drop is known as the burden voltage, specified in volts per ampere.
Current clamp. An electrical transformer in the form of a split ring, which may be opened and clamped around an electrical conductor. The clamp contains one winding of the transformer, and the conductor provides the other. Small clamps are used for measurements, while large clamps are used for signal injection, e.g. for EMC susceptibility testing.
Demonstration model of a moving iron ammeter. As the current through the coil increases, the plunger is drawn further into the coil and the pointer deflects to the right. An ammeter (abbreviation of ampere meter) is an instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. For direct ...
Kill A Watt EZ electricity usage monitor review Archived 2009-05-11 at the Wayback Machine; Conner, Steve (2005-08-30). "Kill-A-Watt vs. analog wattmeter". Tesla Coil (Mailing list) The low power factor means that the DRSSTC was drawing awful peak currents, but the two meters still agreed well.
A Rogowski coil is a toroid of wire used to measure an alternating current I(t) through a cable encircled by the toroid. The picture shows a Rogowski coil encircling a current-carrying cable.
