A clamp meter is an electrical test device that combines a basic digital multimeter with a current sensor.
Clamp current measurement. Measures probe voltage. Integrating an embossed jaw into an electric meter allows technologists to clamp the jaws around wires, cables or other conductors at any point in the electrical system, then measure the current in that circuit without disconnecting / de-energizing. Beneath their plastic moulds, hard jaws contain ferrite iron and the magnetic field produced by the current as it flows through the conductor is detected, thickened and engineered to measure.
Originally designed as a single-purpose test tool, modern clamp meters provide more measuring functions, greater accuracy, and in some cases specialized measurement features. Today's clamp meters include most of the basic functionality of a digital multimeter (DMM), such as the ability to measure voltage, continuity and resistance. Clamp meters have become popular tools primarily for two reasons: Safety. Clamp meters allow electronics to cut into wires and bypass the old-school method of inserting a meter test to take a lined in-line current measurement. A clamp meter jaw does not need to touch the conductor during a measurement. Convenience. During a measurement, the current does not need to close the current-carrying circuit is a great incentive for efficiency. Clamp meters are preferred for measuring high current currents. DMMs cannot measure current at 10 for more than 30 seconds without the risk of meter damage. Clamp meters offer a minimum current range from 0 A to 100 A as in models 2500A. Clamp meters are used in industrial equipment, industrial control, residential/commercial/industrial electrical systems and commercial/industrial HVAC. These are primarily used for:
