Technical Field

[0001] The utility model relates to the technical field of measuring instrument detection, in particular to a measuring instrument detection and calibration device. Background Art

[0002] A weight is a physical measuring tool with certain physical and metrological properties and can reproduce mass values. There are very strict regulations on its shape, size, material, surface condition, density, magnetism, mass nominal value, allowable error and other indicators.

[0003] At present, weights are one of the important measuring instruments in market transactions. However, after the weights have been used for a period of time, rust or wear will occur on their surface, which will affect the measurement accuracy of the weights. In addition, in current market transactions, shortages of weights occur from time to time, and there are often transaction disputes. Therefore, whether it is to resolve disputes in transactions or to use weights for a period of time, regular inspections are required. The existing weight detection device is cumbersome to operate, which is not conducive to its application to elderly people with low cultural literacy in the market. For this reason, a detection and calibration device for measuring instruments is proposed. Utility Model Content

[0013] 1. In the utility model, when it is necessary to detect the weight, the tension count value on the standard weight is read in advance, so that when it is necessary to detect and calibrate the weight, the standard weight in the positioning slot on the placement block is removed, and then the weight to be detected is placed in the positioning slot.
