Clamp meter capable of conducting multi-point measuring

Abstract

The invention provides a clamp meter capable of conducting multi-point measuring. The clamp meter comprises a current measuring unit, an analog-to-digital conversion unit and a measuring position judging unit. The current measuring unit comprises more than two current measuring positions corrected according to the measuring position judging unit. The current measuring unit measures current according to the current measuring positions judged by the measuring position judging unit. The clamp meter can measure more than two corrected current measuring positions and output or display the corrected current measuring positions.

Description

technical field [0001] The invention relates to a hook meter, in particular to a hook meter capable of multi-point measurement. Background technique [0002] Like a multimeter, a clamp meter is a commonly used electronic measuring device; a clamp meter measures current in a conductor (such as a wire) without requiring electrical contact. After the hook meter is made, the hook meter will perform error correction, so that the hook meter can more accurately measure and display the current in the conductor. [0003] However, there is a shortcoming in the existing hook meter at present, that is, when the user uses the hook meter to measure the current in the conductor, the conductor must be placed in the center of the hook part of the hook meter (because only the center of the hook part of the hook meter can correct the error) ;Otherwise the current in the conductor will not be accurately measured and displayed; this is very inconvenient. Contents of the invention [0004] In...
