When it comes to scales, we prioritize maximum weighing accuracy. But often, people face the problem when electronic scales show different weights in different parts of the room. The reason may be due to several factors, one of which is the poor quality of the product.
Types of scales
Modern household scales are of two types: mechanical and electronic. Mechanical ones have an analog dial, often small, with a division value of 1 kg. Accordingly, the accuracy they give when weighing is +/- 0.5 kg. For most people who just want to know their approximate weight, this option is suitable. However, for athletes, as well as in medicine, such accuracy is not enough. Electronic scales give the result with an accuracy of 100 grams (some models show every 10 g). The value is displayed on the screen. Advanced models of scales have additional features, such as a built-in calculator/body analyzer that allows you to calculate the proportions of the body by component composition right during weighing. You can check details on the appropriate website.
Structurally, electronic scales consist of some kind of sensor and a result display system. In simple inexpensive models, there is a spring sensor, the data from which is digitized and goes to the scoreboard. Newer models have a warp converter. Such devices have maximum accuracy, as they are completely electronic. Most often, they have built-in intelligent systems that allow you to determine additional information about the state of the body.
Why do electronic scales can “lie”?
It happens that several weighings made in a row have different results. This problem is common and frustrating for users. The reasons for it lie in the improper operation of equipment and in small nuances in the weighing process.
The main reasons are discussed below:
- The scale must be placed on a perfectly level floor. Any unevenness makes the sensor work incorrectly. In this situation, it is necessary to place the scales in another, more suitable place.
- You also need to stand on the scales correctly: evenly, without pressure or skew on one of the sides. Feet should be placed parallel to each other, on the same level. It is advisable to stand on the platform at each weighing, equally positioning your legs and evenly distributing your weight.
- Feet should be on the platform with the entire surface of the foot and body at right angles to the horizon. Point pressing with heels and/or fingers can significantly distort the result.
- Electronic scales work with sensitive sensors. Negative environmental influences, such as large temperature fluctuations in the room, can affect the measurement accuracy.
- It has been noticed that scales placed near heating devices can also show a result that differs from the real one.
- It is important to care for electronic scales properly. In particular, washing them with aggressive detergents is strictly prohibited. Chemical ingredients can adversely affect sensors and electronics that convert measurement information. Glass scales are best suited for household use: they are quite accurate and easy to care for.
Any electronics requires a careful operation. To avoid problems, and the measurements are as accurate as possible, you should study the user manual.
Possible tech issues that may occur to electronic scales
If floor scales are operated correctly, and the result is different each time, they are most likely broken. It is possible to carry out a preliminary diagnosis of a malfunction.
- The scales do not turn on, and no information is displayed on the screen at all. This may indicate that the device is not powered; that is, its power supply (battery) is dead. To solve the problem, it is enough to replace the batteries with new ones. In advanced models, a dead battery gives a specific error code.
- No contact of the loop on one of the sides. This element connects the electronic unit and the visualization unit (display). If the cable has moved away from one of the elements, the scales may show incomprehensible symbols or nothing at all. You can solve the problem by removing the protective cover and inserting/pressing the board more tightly to the display.
- It happens that the scales show an unexpected result. For example, an adult person weighs 15 kg or weighs 30 kg more than yesterday while not changing outwardly. Most often, the matter is the wear of the contact elements. In this case, the relay must be replaced.
- The appearance of gaps that are not provided for by design leads to damage. This happens if the device stays on the floor all the time and is not put away in the package, and is not cleaned regularly. In this case, your scales must be disassembled and all components carefully cleaned with a soft brush.
- Another reason the scales can “lie” is the incorrect calibration of the device. Some models do it automatically when installed on the surface and turned on; others must be configured manually. You can consult the user manual on how to do this.
In order to avoid problems with purchased scales in the future, you should listen to the opinion of experts who recommend paying attention to the following points:
- If you come across a model with a choice of units, make sure that the table contains kilograms.
- For use in the bathroom, it is worth buying a model with moisture protection.
- For comfortable use, choose floor scales not with a smooth surface but with a rough surface.
- When choosing a material, it is better to trust metal models rather than plastic ones.
- Don’t skimp on your purchase. Cheap models are short-lived, the weight shown by them is not always accurate, and as a result, you will overpay for repairs or buying new scales.
- Be sure to check the accuracy of the measurements before purchasing.
- When working with scales on a carpet, the calculation error can be up to 10%.
- Do not use models that are not designed for your weight.
- Magnetic radiation from devices located in the room can affect the quality of weighing, so make sure that your device is located away from radio equipment.
- When buying electronic models, choose a model with four sensors. This information is not always indicated on the price tag, so you must look into the device’s passport.
- The more built-in functions in the device, the greater the error of their calculations. Try to choose simple and reliable models.
Do not forget that electronic scales run on batteries that need to be changed at least once every six months.
