How do my bioelectrical impedance analysis scales measure my body composition?

Bioelectrical impedance or bioimpedance analysis works using a weak current that is sent through your body with electrodes from one foot to the other at different frequencies. The time it takes for these signals to pass through your body depends on the tissue that they encounter along the way. Adipose tissue (body fat) does not conduct, so it slows down some of these signals. The different signal speeds measured by your scales are then used to calculate your body composition in detail using different algorithms.

What is the difference between the"standard" profile and the"sports" profile?

The"sports" mode enables the calculation algorithms of your scales to be adapted to people exercising intensively. We consider exercise to be intensive from 12 hours of practice a week.

What are the safety precautions for using the scale 500 impedance analysis scales?

For an accurate measurement, it is important to follow the advice below:- Place the scales on a hard, flat surface. Soft surfaces, such as carpet, may affect the measurements.- Avoid moving the scales between measurements.- If you have to move the scales before a measurement, wait for the scales to display"0.0" before you step on- Use the scales barefoot- Place your feet on the electrodes, centre your body and stay still while the measurement is taken

What are the best conditions for weighing yourself with impedance analysis scales?

To make sure that measurements are as relevant as possible, it is best to weigh yourself:- at the same time of day each time- on an empty stomach- with an empty bladderIt is not advisable to drink diuretic drinks such as alcoholic drinks or coffee before weighing yourself.It is also not advisable to weigh yourself after intense exercise. Your glycogen (and therefore hydration) levels will be greatly reduced which will distort the measurement.It is also very important to not repeat measurements several times during the day, these values are not comparable.


What is body fat?

Body fat includes all of the fatty mass within your body.It is essential for the healthy functioning of the body. It is an energy reserve which is mainly used by the body during extended periods of low to moderate-intensity activity.

What is muscle mass?

Muscle mass represents all cells that make up the muscles of the body. In the case of an intensive dietary or workout plan, make sure you have a varied and balanced diet to maintain your muscle mass.

What does basal metabolic rate (or basal metabolism) mean?

Your basal metabolic rate is the energy required by your body to keep it functioning properly. The greater the muscle mass, the higher the basal metabolic rate. By adding the energy used in your sporting activities, we can find your total daily energy expenditure.

How accurate are my impedance analysis scales?

There is currently no 100% reliable solution for measuring an individual’s body composition. All body composition measurement solutions, even the most professional ones, are approximate.Furthermore, all impedance analysis scales have their own calculation algorithms and their own benchmarks, it is therefore important to refer to the value correspondence table in the instruction manual.We therefore recommend that you focus on monitoring changes in body composition parameters rather than the gross value.

What is the body mass index (bmi)?

Body mass index (BMI) is a simple weight to height ratio that is commonly used to assess whether an adult is overweight or obese. It corresponds to the person’s weight divided by their height squared, expressed in kg/m2.

Another question?

I have an implanted medical device, can i use impedance analysis scales?

Using impedance analysis scales is not recommended for people with pacemakers or any other type of implanted medical device. In case of doubt, ask your doctor for advice.

What is the benefit of knowing your level of body fat?

Weight alone is not sufficient to determine your overall condition. With impedance analysis scales you can assess what proportion of your weight comes from body fat or muscle mass. Furthermore, these parameters do not change in the same way when you are physically active. For example, weight gain when taking up sports again may simply be due to the fact that your body is toning up again.

How many times a month should i weigh myself?

As with weight, body parameters such as body fat or muscle mass change slowly. It is not necessary to weigh yourself every day. One measurement a week is sufficient.

The error message "c" appears on the screen of my scale?

For scale 500, if you moved the scale when it is ON, the scale will show message "C".

(Normally, when you move the scale, you need to wait 3 seconds before weighting to avoid inaccurate measuring).

When the error "C" shows, you can take out the batteries and reload again, wait 3 seconds before weighing.

To maintain

Thanks to its large glass plateform, your scale is easy to clean.
You can clean it with a slightly damp cloth.
Since the plateform is made of glass, we advise you to handle your scale with care to avoid scratches or breakage.
Wait until your scale is completely dry before you step on it to avoid slipping. For the same reason, we recommend that you do not step on your scale with wet feet.

To repair

The following repairs can be carried out on this product:

Change the batteries:
- Turn your scale over to access the back.
- Remove the battery cover and change the batteries, observing the polarity: the + of each battery on the - and the - of each battery on the +.
- Replace the battery cover.
- You can return your used batteries to our DECATHLON shops or dispose of them in the appropriate containers.
(Batteries are available in the "Spare Parts" section on this page).

- If you do not use your scale, please remove the batteries and do not leave it in a damp place.

If your product cannot be repaired, take it to a WEEE picking point or any DECATHLON shop for optimal recycling.
