Cut cakes from Xinjiang Party to discuss weighing instruments

On December 3, 2012, an incident of quarrels and gangsters in Hunan Province took the cake and cut the cake to a fire. The unrecognized value of a car cut cake was as high as 160,000 yuan. Therefore, many netizens joked that “cakes are handsome and rich,” “we would rather cry on a cut cake car, and would not like to laugh in a BMW car” and “cut a cake. One square, a cut cake for the suites...” Although this is a joke, but it is also reflects the public's attention to the cut cake event. When everyone was concerned about the cut cake event, Xiao Bian talked about weighing instruments from the cut cake event.

Regardless of whether they often go shopping or go out occasionally, Xiao Bian believes that everyone has encountered small vendors selling goods in small carts along the road. Goods on small carts are often cheaper and more reasonable in price, often attracting some people. There are some problems in the purchase process that can be unavoidable. Among them, the most concern is the problem of hawker weighing instruments. Many consumers have bought goods back and found that the shortage of goods is very serious. What should be done? Avoid this kind of deception problem? Xiaobian to sell cut cakes for example.

First of all, we must first understand the working principle of electronic scales in order to find out that traders are making ghosts on weighing instruments. Electronic scales are tools for determining the quality of objects using the Hooke's law or the principle of force balance. Electronic scales mainly consist of load-bearing systems (such as scales, scale bodies), force transfer systems (such as lever transmission systems, sensors), and indication systems (such as dials, electronic display instruments). When the cut cake is placed on the weighing pan, pressure is applied to the sensor to deform the sensor, cause the impedance to change, and output a changing analog signal through the voltage change. The signal is amplified and converted into a digital signal output and the result is displayed.

So how are the traders moving their hands and feet? First, there is a problem with the electronic scale itself; second, the table is tilted, resulting in less than two; third, the weighing pan mixed with water; fourth, the circuit is installed on the circuit board of the scale, which can be remotely controlled.

For consumers, how to prevent it? The easiest thing is to find one of your own belongings and use the exact scale to weigh its exact weight. When you are skeptical about the purchase of the weighing instrument, you can let it go. By comparing you can determine the scale of the trader. Not allowed.

Cut cake industry is profiteering, perhaps for many compatriots in Xinjiang, they also adhere to their own professional ethics, but it is also difficult to keep some traders corrupt their own industry image for some interests. Therefore, knowing more about the industry's tricks and being prepared for it will make it easier for everyone to buy carts.
