How to prevent electronic scales from cheating

How to prevent electronic scales from cheating?

According to the person in charge of the relevant departments of the Municipal Quality Supervision Bureau, the accuracy of the electronic scale is much higher than that of the pole scale. This is because the electronic scale uses a displacement sensor. After a series of processing, the signal is converted into a weight value, which can be more accurate and faster. The ground reflects the weight value of the weighed material.

There are several tricks for doing tricks on electronic scales:

1. After the finished product is not restored to zero, it will continue to press the cumulative button to refer to the next item, so that the second weighing shows the sum with the previous weight;

2, the sale of goods on the reel, the electronic scales empty scale display is indeed zero, but when the plate and the goods are placed together on the electronic scale, the weight of the plate has become the weight of the goods;

3, stealing the beam and changing the column, first put a light weight scale on the consumer to buy the goods, the merchant put another heavy weight weighing pan together with the goods on the scale, the quality of the weighing pan is converted into goods The amount is added to the consumer's account;

4, electronic scales, empty scales, digital display screens should be zero, but before the operator weighs a certain number of bases in the display of the weight of the number, these bases are valued together with the purchased goods, careless consumers generally do not Will pay attention to;

5. When the operator sells the goods, he will throw the goods into the weighing pan heavily, and use the inertial impact force to make the electronic value display instantly increase artificially, and then pick up the goods immediately;

6. At the time of settlement, by the quick operation of the button, the weight or unit price is secretly added with a few zeros and then multiplied, so that the total amount calculated after zui is increased;

7. Deliberately stacking debris in front of the electronic screen, so that the careless consumers do not seriously read the subtitles, thus arbitrarily deceiving the ghosts;

8, do not adjust the unit price, the price is also calculated according to the high price of the weighing; use a hard object or paper pad to the height of the body, so that the weight of the weighing is biased; the packaging is calculated in the value of the goods, such as crabs and grass ropes together Weighing, weigh the straw with water and seafood together. No verification is illegal

Relevant personnel of the Municipal Quality Supervision Bureau reminded the public that in addition to paying attention to the above-mentioned means of unscrupulous traders who harm consumers, it is also necessary to confirm whether the electronic scales used for weighing are in accordance with national requirements, because electronic scales are a measure of national compulsory verification. Every year, the appliance shall be periodically verified by the metrological verification department. The qualified certificate shall be issued and the elliptical red qualified label shall be attached to the scale. The label shall have a valid period of validity, so as to ensure accurate measurement, the electronic scale It is subject to metrological verification and is used within the validity period, otherwise the scale is illegally used. Can go to the quality supervision department to complain.
