Background

The electronic scale is used in more occasions because of its small and exquisite flexibility, need use the electronic scale to weigh to the object usually to know the weight data of object. An electronic scale is a kind of weighing apparatus, and is a tool for measuring the mass of an object by using hooke's law or the principle of lever balance of force. According to the structural principle, the mechanical scale can be divided into three categories, namely a mechanical scale, an electronic scale and an electromechanical combination scale. When an object is placed on the scale, pressure is applied to the sensor, which deforms elastically, causing a change in impedance and, at the same time, a change in the applied excitation voltage, outputting a changing analog signal. The signal is amplified by the amplifying circuit and output to the analog-to-digital converter. The digital signals converted into the signals convenient for processing are output to the CPU for operation control. The CPU outputs such results to the display according to the keyboard commands and the program. Until such a result is displayed. Along with the development of society, various electronic scales are gradually derived.

Under some occasions that are difficult to move, the electronic scale needs to be swung flat when weighing, and many occasions are difficult to be swung flat and can appear that the electronic scale counter weight is unbalanced when leading to weighing.
