Background technique

A balance, a weighing instrument. The balance beam is supported by the fulcrum (axis) at the center of the beam to form two arms, and a plate is hung on each arm, one of which contains an object of known mass, and the other contains an object to be measured, fixed on The deflection of the pointer on the beam when it is not swinging and points to the middle scale indicates the mass of the object to be measured. A balance is an equal arm lever. A balance is a weighing instrument, an instrument for measuring the mass of an object. It is made according to the principle of leverage. There is a small plate at both ends of the lever. A weight is placed at one end, and an object to be weighed is placed at the other end. There is a pointer in the center of the lever. When both ends are balanced, the mass (weight) of both ends is equal. Modern balances are becoming more sophisticated, more sensitive, and more diverse. We all know that there are ordinary balances, analytical balances, constant analytical balances, micro analytical balances, semi-micro analytical balances, and so on.

At present, the purpose of calibration is to compare the measurement standard, evaluate the indication error of the measuring device, and ensure the accuracy of the value. It belongs to a group of operations that trace the source of the value from bottom to top. The evaluation of this indication error should be regulated according to the organization's calibration procedures, and should be carried out according to the calibration cycle, and the calibration records and calibration marks should be made. Calibration In addition to evaluating the indication error of the measuring device and determining the relevant metrological characteristics, the calibration result can also be expressed as a correction value or a calibration factor, which specifically guides the operation of the measurement process. However, in some verification methods in the prior art, most of the data are single-step simple , cannot meet the refined verification requirements, and is not conducive to the accuracy of balance verification. Therefore, in order to solve this problem, it is very necessary to design an efficient balance verification device and method.
