There are several tricks for manipulating electronic scales, including:

1. After weighing the product, it does not return to zero position, but continues to press the accumulation button to weigh the next product. This way, the second weighing display shows the total weight compared to the previous weighing;

2. Selling goods with a tray, the empty balance displayed on the electronic scale is indeed zero, but when the tray and the goods are measured together on the electronic scale, the weight of the tray has already become the weight of the goods;

3. Stealing a beam and replacing a pillar, first placing a lightweight weighing pan on the scale for consumers to purchase goods, but the merchant places another heavier weighing pan on the scale together with the goods. The difference in weight of the weighing pan is then converted into the amount of the goods and added to the consumer's account;

4. The digital display screen of the electronic scale should be zero, but before weighing, the operator stores a certain number of base numbers in the displayed weight, which are then priced together with the purchased goods. Careless consumers generally do not pay attention to this;

5. When selling goods, the operator throws the goods heavily into the scale, uses inertial impact force to artificially increase the electronic value display instantly, and then immediately picks up the goods;

6. During settlement, by quickly operating the buttons, a decimal point is secretly added to the weight or unit price and multiplied to increase the final calculated total amount;

7. Intentionally stacking clutter in front of electronic screens, causing careless consumers to not pay attention to subtitles and manipulate them at will;

8. Do not adjust the unit price, and calculate the weight based on the higher price even if it is cheaper; Raise a corner of the scale body with a hard object or paper to make the measured weight heavier; Calculate the packaging within the value of the goods, such as weighing crabs together with grass ropes, pricing grass ropes with water together with seafood, and so on. Without verification, it is considered illegal use
