A new electronic personal scale that allows to evaluate your body composition and to automatically
calculate the body fat and water percentage in function of your height, age and sex. The exact
knowledge of your body composition (calculation of lean body mass, fat body mass and total
body water contents), allows a correct estimate of the excess fat and at the same time determines
the advisable weight as a function of your nutritional condition.
Furthermore, the knowledge of your body composition allows to combine a correct nutrition and
physical activity as essential conditions to improve the quality of life, promote health and prevent
pathologies. It has a memory function with a 10-person capacity.

Warning!
• The body fat and water percentage is to be considered only as approximate
information.
For any further information, please consult your physician or dietician.
• Self-measuring means control, it does not mean diagnosis or treatment.
Any unusual levels should always be discussed with your doctor.
Under no circumstances must you change the dose of medicines prescribed by
your Doctor.
IT IS IMPORTANT TO CAREFULLY READ THE INSTRUCTIONS AND WARNINGS IN
THIS BOOKLET BEFORE USE AND TO KEEP THE BOOKLET IN A SAFE PLACE.
BODY COMPOSITION
It is important to know the body composition of an individual in order to be able to estimate his/
her health condition.
Actually, it is not enough to know one's weight but it is necessary to define its quality, which
means dividing the human body in its two major component masses:
• lean body mass: bones, muscles, viscera, water, organs, blood;
• fat body mass: adipose cells.
Under the same conditions of weight, these two masses have different volumes.
By means of electrodes placed on the platform, the scale sends a weak low intensity electric current
that passes through the body mass. The electric current reacts in a different way according to
the masses it passes through: the lean body mass opposes a weak resistance, while the fat body
mass has a greater resistance.
This body resistance, called bioelectrical impedance, varies also in function of sex, age and
height.
For a correct control of one's ideal weight, it is important, besides the weight, to compare the
ELECTRONIC PERSONAL SCALE WITH INDICATOR OF % OF FAT AND % OF WATER
body fat percentage calculated by the scale, with the parameters contained in the table and the
body water percentage, with the information listed hereinafter.
If the percentages are outside the normal values, we suggest you to consult your
doctor.
In order to better understand the value of your body fat percentage, we suggest you write down
this value for a given period of time. In order to obtain a valid comparison, you should weigh
yourself always at the same time of the day and under the same conditions. The best moment to
weigh yourself is in the morning, before breakfast, without clothes. You have to wait 15 minutes
after getting up, so that the water get distributed itself throughout the body.
Body fat mass percentage
The percentage of fat listed in the following table, represents the total fat, calculated by summing
up the essential fat (or primary fat) and the spare fat (or storage fat). The essential fat is necessary
since it is needed for the metabolism. The percentage of this fat is different between the two
sexes: about 4% for men and about 12% for women (percentage calculated on the total body
weight). The spare fat, which is theoretically superfluous, is necessary in a minimum quantity
for a healthy condition, especially for those who carry out physical activities. Even in this case,
the fat percentage is different between the two sexes: 12% for men, 15% for women (percentage
calculated on the total body weight). Therefore, the normal percentage of fat mass on the body
weight is approximately 16% for men and 27% for women. Such percentages differ with the
person's age as shown in the table here below.

Water percentage
Water is the main component of lean body mass; the water percentage over the fat body mass is
73%. The lean body mass is obtained by subtracting from the total weight the fat body mass (for
