The measuring principle
These scales work according to the B.I.A. (Bi-
oelectrical Impedance Analysis) principle. For
this purpose, an imperceptible current, which
is absolutely safe and risk-free, enables you to
find out body tissue levels in seconds. Electri-
cal resistance measurements (impedance), as
well as taking into account constants or individ-
ual data (age, height, sex, physical activity), are
used to define the levels of body fat and other
physical parameters. Muscle tissue and water
have good electrical conductivity and there-
fore have low resistance. On the other hand,
bone and adipose tissue have a low conduc-
tivity, as the bones and fat cells are very poor
conductors due to their very high resistance.
Note that the values determined by the diag-
nostic scales represent only approximations
compared with actual medical physical anal-
ysis. Only a specialist equipped with medical
equipment (for example, a CT scanner) is able
to accurately determine body fat, body water,
muscle mass and bone mass.
General advice
Weigh yourself, if possible, at the same time
(preferably in the morning), after going to the
toilet, before eating, and without clothes, to
obtain comparable results.
Important when measuring: Body fat determi-
nation must always be made with bare feet; if
necessary, it can be carried out with the soles
of the feet slightly damp. Measurements taken
with completely dry feet may not lead to satis-
factory results, as their conductivity is too low.
Note: there should be no skin contact between
feet, legs, calves and thighs. Otherwise, the
measurement may not be performed correctly.
Hold straight and do not move during the
measurement.
Wait a few hours after unusual physical exertion.
After getting up, wait about 15 minutes before
taking the measurement so that water can be
distributed through the body.
Note that only long-term trends count. Short-
term weight fluctuations recorded within a few
days of each other are only due to fluid loss
in most cases; body water plays an important
role in well-being. Limitations The determi-
nation of body fat and other data may pres-
ent implausible deviations and results in the
following cases:
• children under 10 years old,
• top-level athletes and body-builders,
• people who have a fever, are on di-
alysis, who have symptoms of
oedema or osteoporosis,
• people on cardiovascular (heart and
vascular system) medical treatment,
• people taking vasodila-
tors or vasoconstrictors,
• people with serious anatomical dif-
ferences in the legs in relation to their
size (significantly short or long legs)
