Electronic scales under the foam will gain weight. "Electronic scales to defoam the foam box, see you go, let more people know it! The post mentioned: If you see a foam box under the electronic scale, whether it is selling meat or selling vegetables, fruits, generally are not allowed. At the end of the post, a physics teacher added that the underlay of a foam box on the scales will cause the electronic scales to deform and buffer and generate upward acceleration. As a result, the tray's support for the objects is greater than the gravity of the objects and the overweight phenomenon occurs. The pointer reading is too large. After the release of this website, it received extensive attention. There were a lot of readers and users who liked it.
Merchants: There will be no online complaints. In order to confirm the situation mentioned in the post, the reporter visited a number of farmers' markets in Shenyang.
Jixian Market is an old market that has existed for several decades. The reporter saw some merchants padding foam boxes under electronic scales, some of them put foam on the scales, and many merchants simply put scales on shelves. For the practice of placing foam boxes under the scales, the merchants stated that they were to keep clean and lay flat scales. "The main reason is that electronic scales are not directly on the board, but they are easy to get into something dirty, so we'll use a foam pad for the next time." Those who put foam on electronic scales are mostly fruit sellers, they say, Prevent fruit from falling. Regarding whether or not there will be a shortage of goods, all merchants said: "Impossible. Now that it is strictly controlled, we can't joke about our 'rice bowl'."
In the Shashan farmers market and a farmer's shop in southern Anhui, most of the merchants said that they did not hear the Internet, their electronic scales are checked, and there will be no online statement.
Experiment: The pad is not as heavy as the foam. "My family has three electronic scales. You can experiment freely." A merchant at the market in Jixian told reporters to verify the authenticity of their posts.
On the electronic scales padded on the foam box, the reporter first put five tomatoes, which showed a weight of 0.970 kilograms, and put a broccoli again, showing a weight of 0.490 kilograms. Afterwards, the reporter began to remove the foam and placed the electronic scale on a horizontal board. The tomatoes and broccoli were placed on the scale again. The weight shown above was the same as the reading on the electronic scale just placed on the foam. A merchant told reporters that they will only make up for the public's advantage when the scale is not zero. "Whether or not something is scaled above or below the scale, as long as we measure zero, there will be no shortage of goods. If we do not return to zero, the goods will be less than one or two."
Afterwards, the reporter came to the market administration office with tomatoes and broccoli, and the same value was stated on the fair scale. Staff said that they also heard similar rumors, but the claim that the foam box will increase the weight of electronic scales is not valid. Electronic balances will not be misaligned if they are placed on objects and will not affect the measurement results. “We regularly check the electronic scales of the merchants in the market. If the citizens are still not confident, they can go to the fair scale in the market to re-enumerate.â€
In order to prove the experimental results, the reporter telephoned a physics teacher from a certain university in Shenyang. He said that if the underlying support plane is flat, then the electronic scale shows the pressure of the object on it and then passes the signal of this force through. The sensor is converted into a quality signal output, which should not be the case mentioned on the net post.
