Regular weight measurement is the prerogative of not only losing weight, but also carefully monitoring their health. Initially, everyone used mechanical scales, whose operating principle is based on measuring the impact on the spring. Such scales, although they do not require power and do not depend on the proximity of electrical appliances, still fail soon as the spring loses elasticity.
The invention of floor scales made it possible to obtain more accurate results. There was a sense in daily weight measurement, as now the slightest gains and plumbing became visible. This significantly increased the number of their purchases, which contributed to the expansion of the market.
Functions of Electronic Floor Scales
The main function of the floor scale is the accurate measurement of weight. In the electronic version, it is based on a change in the deformation of the platform under the weight of a person. The scales are mounted on special legs, and under the influence of gravity the platform frame is deformed. This is invisible to the human eye, but data analysis is performed using several readings of resistance (usually three).
IMPORTANT. Sensors are thoroughly glued to the device, so it is highly not recommended to disassemble it.
Features
In addition to the principle of operation, electronic differs from mechanical scales by an error.Depending on the model, it varies in the range of 0.1-0.5 kg. There are more accurate options, but they also have a high cost, while changing hundredths of a weight does not make much sense when tracking body mass dynamics.
Due to the popularity of the use of the device, they are carried out in various designs, which allow it to be advantageously built into the general appearance of the room. Often, the top panel is roughened or ribbed to reduce slippage. Some models specifically indicate where you need to get your feet to get the most accurate values. To expand the application areas of the device, many manufacturers produce moisture-resistant and waterproof models, which allows you to safely install them in baths and spas.
How to use
How to use electronic scales? For proper weighing, it is important to pay attention to two things:
- device location;
- appearance of a person.
The main role in accurate weighing is played by the correct installation of the balance. When weighing with an electronic balance, they must be placed on a flat, solid surface. Installation on carpets may result in errors of up to ten percent. Some accurate scales give a bad result on linoleum. It is best to place the device on a tile or, in its absence, on a stable stool.
Before weighing, it is recommended to remove all jewelry and heavy items of clothing: shoes, sweaters, pants, etc. Do not forget that measuring weight with wet hair is even more useless than weighing on a carpet (depending on the amount of hair it can add a few kilograms to your real weight).
Precautionary measures
Since the scales are an electronic device, it is worth standing on them with only dry feet. It also protects you from possible slipping.
The stability of the scales also directly affects the safety of their use. With improper weight distribution it is very easy to lose balance and fall.
Additional functions of electronic scales
Many electronic floor scales now, in addition to accurate weight measurements (usually up to 0.1 kg), have acquired a good list of additional functions. Among them are most often found:
Display backlight- Remote control.
- Automatic shutdown (which greatly saves battery power).
- Difference in weighing units.
- Musical accompaniment.
- Determination of the percentage of adipose and muscle tissue (using a transmitted electrical signal).
- Clock, thermometer, growth meter.
- Storage of information on the dynamics of changes for several users.
- User definition (with regular measurements).
- Audible warning of a sudden change in weight.
- Calculation of BMI, etc.
Display backlightIMPORTANT. Using the function of measuring adipose and muscle tissue is not recommended for pregnant women and is strictly prohibited for people with pacemakers.
This functionality is still unlimited, as many manufacturing firms in the competitive race are adding more and more new features.
