Diagnostic scales: how they work, how to choose

For those who are interested in sports and watching their health needs in the range with simulators and household floor diagnostic scale. It is noted that regardless of whether a person is engaged in sport or not, as soon as the house there is a Required appliance - the total mass is reduced by up to 500 grams, even without special compliance diet.

Function, pros and cons

Work from ordinary batteries 1.5 - 9V There are some instances that run on solar cells using solar energy (Solar batteries) or accumulating the energy that transmits the mechanical devices when they are constant use.

Reset to zero occurs automatically at power up or by pressing a button located on the housing.

The main purpose - the measurement of body weight. This is an important indicator of health. But do not want to learn, and the ratio of water, muscle and fat mass, bone tissue throughout the body.

Function diagnostic scales:

1. It tracks the performance of all parameters for the desired period of time.
2. Independently calculate the recommended setting for "Body Mass Index" technology, where growth has to be taken into account sex, age and structure of the organism.
3. If multiple users - themselves determine who is currently standing on them.
4. Can choose a personalized diet for a specific person and give advice on physical activity.

Advantages diagnostic floor scales

They are used to prevent diseases. Athletes during training with their help pick the right training schedule and diet. Can detect the disease at an early stage and in time, seek medical attention.

With their help, any time you can see the percentage of fat, bone and muscle mass, water. If you enter personal data (height, gender, age), you can get advice on the use of calories per day. Setting the weights does not cause much difficulty, if you follow all the rules set out in the summary, which is attached to any device.

Disadvantages disadvantages diagnostic floor scales

For proper operation even surface. On uneven floors can be shown large differences in the measurements. Some models have the property when issuing diagnostic results "hang" for a while and give different values. To obtain correct results of diagnosis is necessary to get up on the measuring platform with bare feet.

How do the diagnostic scales

The basis of operation of the instrument, capable of diagnosing an organism, based on the principle of "biological impedance" - comparison of the results of an electrical current through the human body.

Such devices can operate under the condition that they stand bare feet. Once a person is on the platform - the circuit is closed, and a weak electrical signal is passed through it. Then he goes back into the device where special software analyzed.

The measurement is started with the input data required:

• height;
• age;
• floor.

The obtained data is analyzed based on the fact that different parts of the body current flows differently.

• good electrical conductivity and possess water muscle tissue of the body, respectively, there is a small electric resistance;
• and almost non-conductive adipose tissue and bone.

Indicators

In addition to the weight of the program displays the following information:

• visceral fat - if the rate is high, a higher risk of disease: diabetes, cardiovascular illnesses and oncology;
• The percentage of water content in the body - indicates the ratio of liquid to total body weight. If this index in the normal range - less risk of disease;
• The volume of bone mass - indicates the total weight of the bony skeleton. The normal level indicates no health problems;
• To issue the dynamics of physical condition;
• Level of basal metabolism - shows that the minimum energy level that is required for standard operation of the whole organism. If the figure is closer to 70% - health is all right. Its value is closely related to age. On the basis of the number of models can determine the biological age of a person.

• Calculation of the physical condition rating - calculated from the results of readings of fat and muscle tissue. It shows the general state of the organism;
• The recommended daily amount of calories by sex and age;
• bone mass - data showing the overall skeleton.

Electronics is able to calculate the coefficient of body weight.

To understand the health status, BMI results are as follows:

• <14 - an acute shortage of weight;
• 14 to 22 - the lack of mass;
• 22 - 26 - everything is fine;
• 26 - 31 - excess weight;
• > 31 - the state of obesity.

These averages.

If there was a change of indications with previous measurements - a beep sounds. Additional monitor makes it easy to use for obese people and those with poor eyesight. At the balance turn on / off.

Modern diagnostic mechanisms are synchronized with your tablet. You can see the readings on the display android device and see the graphs:

• the weight;
• fat percentage;
• arterial pressure;
• temperature;
• sugar content.

Special program with intuitive interface in measurement mode for athletes synchronized with the iPhone or iPad.

How to choose the diagnostic scales

For customers who are not familiar with this type of devices, there are options to choose from:

1. cost of - advanced things more expensive, but will last much longer.
2. Permissible load - model operate in the range from 0 to 150 kg.
3. display type - remote or built-in, size and brightness.
4. Feeding power - batteries / battery.
5. Availability of diagnostic functions.
6. Appearance - the choice is wide enough to buy a model from a range of colors that will suit the taste fastidious buyer.
7. housing - cheap plastic, but he also fragile. Preferable to models made in a metal case. There are models with natural stone body.

As with all instruments, in such precise devices have limitations on the maximum permissible limit of weighing - 160 kg. But sold and with a limit of up to 220 kg. Restriction 220 kg designed for people with too high values. If a family has obese people, better for them to choose the mechanism to spare.

All gauges have a margin of error. The most expensive electronic scales can "lie" only 98 grams. And if you need to know, per diem change in grams, it is best to purchase the least error.

How to use

1. If the electronics are working in areas such as bathrooms (sauna), recommended model, made in waterproof housing.
2. Foot pad - corrugated or rough. So avoid slipping. An interesting model in which to place measurements indicated a human foot.
3. Stability - is also needed. If there is a mechanism for leveling on uneven surfaces, the safety is increased.
4. Metal housing reliably.
5. Mechanical must after pressing return exactly to zero.
6. For people with impaired vision fit model with a red dial and digital display.
7. The floor level and stable. Porous surfaces are not suitable for measurement because the measurements are given on tilting from 10% error.
8. If we assume overload - the mechanism breaks down.
9. Avoid close proximity to electromagnetic radiation from near-standing radio.
10. If there was a malfunction - it is better to turn off for five minutes, and then on again.

Precautionary measures

For safety reasons, do not stand on their feet area in nylon pantyhose or stockings, socks and wet feet. Feet can slip off.

Be necessary when weighing exactly (vertical) without tilting. Before taking readings from the instrument to take a stable position and not move. No need to shift from one foot to the other - you can tuck the leg or get inaccurate readings.

Regularly clean the surface with a damp cloth. Cleaning agents are not recommended - you can wash off the paint and drawing from the case.

malfunctions

The balance is not included - 50% of cases the reason is a discharged battery. Replacing a new battery corrects the situation.

Show the wrong weight:

1. The uneven surface and soft floor covering (insulated linoleum, carpet) necessarily cause malfunctions. Help troubleshoot installation on flat and rigid base.
2. When transporting occurred skewed legs. On the scales stand, ponazhimat legs at various points where the sensors are installed. Then get off the site and give their own disconnect. Now the device can be used.
3. Sami pads on feet may have a manufacturing defect in the form of cracks. It will only return on the warranty card.
