A clamp meter is an electrical analyzer that joins a voltmeter with a clip compose current meter.
Like the multimeter, the clasp meter has gone through the simple time frame and into the computerized universe of today. Made basically as a solitary reason test apparatus for circuit testers, the present models have consolidated greater estimation capacities, more precision, and in a few instruments, some exceptionally uncommon estimation highlights.
The present clamp meters a large number of the fundamental elements of a Digital Multimeter (DMM), however with the additional component of a present transformer incorporated with the item.
The capacity of clip meters to quantify expansive air conditioning streams depends on basic transformer activity. When you brace the instrument’s “jaws” around a conductor conveying air conditioning current, that current is coupled through the jaws, like the iron center of a power transformer and into an auxiliary winding which is associated over the shunt of the meter’s information.
A significantly littler current is conveyed to the meter’s contribution because of the proportion of the quantity of auxiliary windings versus the quantity of essential windings folded over the center. For the most part, the essential is spoken to by the one conductor around which the jaws are clasped.
On the off chance that the optional has 1000 windings, at that point the auxiliary current is 1/1000 the present streaming in the essential, or for this situation the conductor being estimated.
Therefore, 1 amp of current in the conductor being estimated would deliver 0.001 amps or 1 milliamp of current at the contribution of the meter. With this strategy, substantially bigger streams can be effortlessly estimated by expanding the quantity of turns in the auxiliary.
