Abstract

The invention discloses a centering weighing device and a weighing method, which relate to the field of measurement. It includes: a base, on which a centering assembly is provided, on which a weighing pan for weighing the piece to be measured is provided, and the centering assembly is used to adjust the weighing pan and the base The included angle between; the support structure is arranged on the weighing pan, and the support structure is provided with a support gap, and the width of the support gap is smaller than the width of the test piece; the loading frame is detachably connected to The base, the loading frame includes a loading table for supporting the DUT; when the loading frame is arranged on the base, the loading table is arranged in the support gap, and the loading table The distance between the side away from the base and the base is smaller than the distance between the side of the support structure away from the base and the base. The possibility of eccentric load error of the test piece is reduced, and the weighing accuracy and stability of the test piece are increased.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a centering weighing device and a weighing method. Background technique [0002] The mass comparator is an electronic measuring device based on the principle of measuring the deformation and strain of elastic elements, or the principle of electromagnetic force feedback balance. Its main purpose is to measure the mass difference based on the ABA or ABBA cycle method, and it is used for high-resolution electronic measuring equipment for weight transfer or other special purposes for testing. [0003] At present, the eccentric load error is an urgent problem to be solved in the field of metrology. The eccentric load error refers to the error caused by the center of gravity of the weight deviating from the center of the weighing pan of the mass comparator. When the user places the piece to be tested on the weighing pan, the center of the piece to be tested is difficult to be at the same po...
