Making eyebrows make the electronic scale "dirty" nothing

When it comes to electronic scales, everyone is certainly not unfamiliar with us. We often come into contact with it in our daily lives. It brings a lot of convenience to our lives, but at the same time it also brings a lot of troubles. Some merchandising vendors often Electronic scales work on top of one another, resulting in the occurrence of shortages and shortages. However, our consumers often suffer from lack of countermeasures or are not very clear about their tricks. Most of them are stifling. So today Xiao Bian gave everyone a detailed account of the small tricks currently used by traders in the market when they are using electronic scales. Let us sculpt a pair of eye-catching eyes so that the electronic scales are intriguing.

First of all, let's take a look. What is electronic scale? How does it work?

An electronic scale, which is a kind of weighing instrument, is a tool for measuring the quality of an object by using the Hooke's law or the lever balance principle of force. The electronic scale is mainly composed of a load-bearing system (such as a weighing pan, a scale body), a force transmission conversion system (such as a lever transmission system, a sensor), and an indication system (such as a dial, an electronic display instrument). According to the principle of structure can be divided into mechanical scales, electronic scales, mechanical and electrical combination of three major categories of scales.

When the object is placed on the weighing pan, pressure is applied to the sensor, the sensor is deformed, so that the impedance changes, while the use of the excitation voltage changes to output a changing analog signal. The signal is amplified and output to an analog-to-digital converter via an amplifying circuit. Converts digital signals for easy processing to CPU operation control. The CPU outputs this result to the display according to keyboard commands and programs until the result is displayed.

Understand the working principle of electronic scales, let's take a look at some common electronic scales "dirty" what?

1, the goods with the skin to weigh together or with the tray weighing the former is weighing the box together to weigh, not the net weight. This is relatively simple and everyone can understand it. The latter requires us to pay attention to observing whether the traders have pressed the keys behind the scales when weighing the goods. We would not normally notice this, and this happens to be the result of merchandising. The empty child. As a result, two different weights will appear, and then the unit price will be displayed in the total price. What we are paying is the price of the goods together with the weight of the tray.

Solution: Decisively ask to remove the package and then weigh it. Pay attention to see if the electronic scale counts 0.000kg with the tray, and pay attention to whether the stall owner has hands or feet.

2, the use of electronic scale into a law this phenomenon is also very common, the general 5 yuan per catty is set to 50, and the standard setting method should be set to 500, because the electronic scales are basically used in the billing method , so that every pen will earn a few cents more.

Coping methods: Before weighing. It is required to set the electronic scale to a standard value.

3, unit price repeat, modify the unit price or "a small tail"

Vendors will often be expensive, and they will not change prices when they call cheaper products. Or increase the unit price when we don’t pay attention. The most commonly used trick is to deliberately not return the count on the electronic scale to zero after the former consumer has left for shopping, but to leave a “tail” to add to the next consumer. In the measurement.

Countermeasures: Pay attention to the unit price of each item and check whether the value on the electronic scale is correct during weighing and whether it is cleared before weighing.

4, under the electronic scales such as foam pads or coins, etc. will make the electronic balance lose balance, the balance of the carrying scale of the electronic scale will inevitably lead to the tilt of the horizontal beads, so that the measurement results are inaccurate.

Countermeasures: Ask the stall owner to move the scale to the level of the surface of the hard object. 5. There are two methods to modify the electronic scale:

One is to modify the unit of measurement, the electronic scale into ninety-two scales, eight two-two or even seven two-scale electronic scales display in kilograms, kilograms and kilograms of the conversion factor should be set to 2.0, but some unscrupulous companies intentionally set the conversion factor 2.1, 2.2 profit. In this way, by adjusting, you can change the pound scale to 92, 82, and 72.

The second is the private adjustment of electronic scales, mainly through the replacement of a part of the electronic scale, to wireless remote control to change the total price. Recently, some local media have also exposed some unscrupulous traders who use remote controls to control electronic scales and wantonly to change the total price of goods. This type of remote control can even be remotely controlled even at remote locations. This is not just a lack of weight. The problem is an illegal act. This kind of behavior is bad.

Solution: You can carry a known weight item with you when you are shopping. When you suspect that there is a problem with the scale, you can put it on an electronic scale to weigh it. If the difference is not large, you can use it with confidence.

In summary, it seems shocking that a small electronic scale actually hides so many tricks. However, when these unsightly secrets are finally defaced, we must not endure these small tricks. As long as we pay more attention and observe more, we believe that these electronic scales will be nothing but stupid.
