When it comes to floor scales, we prioritize maximum weighing accuracy. But often you have to 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 model.

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 (there are models that 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.

Structurally, electronic scales consist of some kind of sensor and a result display system. In simple inexpensive copies, 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 systemsallowing to determine additional information about the state of the organism.

Why 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 even in small nuances in the weighing process.

The main reasons are discussed below.

  1. Libra must stand 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.
  2. 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.

  3. Feet should be on the platform with the entire surface of the foot. Body at right angles to the horizon. Point pressing with heels and/or fingers can significantly distort the result.
  4. Electronic scales work with sensitive sensors. Negative environmental influences, such as large temperature fluctuations in the room, can affect the measurement accuracy.
  5. It is noticed that near heating devices, the scales can also show a result that differs from the real one.
  6. Behind electronic scales it is important properly care. In particular, washing them with aggressive detergents is strictly prohibited. Chemistry 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 careful operation. Libra is no exception. To avoid problems, and the measurements were as accurate as possible, you should study the user manual.

Possible breakdowns of electronic scales

If floor scales are used 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 by the following signs.

  1. Scales do not turn on, on the screen information is not shown 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.

  2. Violation of the contact of the scales 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 balance may show strange characters or nothing at all. You can solve the problem by removing the protective cover and inserting / pressing the board more tightly to the display.
  3. It happens that the scales show 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.
  4. The appearance of gaps, not provided for by the design, leads to breakage of the balance. This happens if the device stays on the floor all the time and is not put away in the package, is not cleaned regularly. In this case, the balance must be disassembled and all components carefully cleaned with a soft brush.
  5. Another reason why scales can lie is because incorrect device calibration. Some models do it automatically when installed on the surface and turned on, others must be configured manually. How to do this, you can see in the user manual for a particular device.

Selection Guide

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 when buying.

  1. If you come across a model with a choice of units of measurement, make sure that kilograms are present in the table.
  2. For use in the bathroom, it is worth buying a model with moisture protection.
  3. For comfortable use, choose floor scales not with a smooth, but with a rough surface.
  4. When choosing a material, it is better to trust metal models, rather than plastic ones.
  5. Don’t skimp on the 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.
  6. Be sure to check the measurement accuracy before purchasing.
  7. When working with scales on a carpet, the calculation error can be up to 10%.
  8. Do not use models that are not designed for your weight.
  9. Magnetic radiation from devices in the room can affect the quality of weighing, so make sure that the balance is located away from radio equipment.
  10. When buying electronic models, choose a model with 4 sensors. This information is not always indicated on the price tag, so you will have to look into the device passport.
  11. 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 6 months.

Rules for care and use

For correct operation, it is important not only to choose and use the device correctly, but also to use it in a quality manner. look after. By following a few tips for maintaining your instrument, you will achieve a longer life and accuracy when weighing:

  1. Electronic scales are known to be extremely sensitive. Therefore, sudden changes in temperature, a large amount of moisture, sudden lowering or shaking, dirt and direct sunlight should be avoided.
  2. Do not bring scales near heating devices.
  3. It is not recommended to use chemicals to clean the device.
  4. Avoid spilling various liquids on the surface of the measuring unit.


When answering the question why your electronic scales always show different weights, we can safely talk about two factors. First, your electronic model is a mechanical fake. Second, your floor surface is not perfectly flat. If both of these factors are absent, and the scales still show incorrect results, you should contact the master, most likely your device is broken.
