The measuring principle
This scale operates according to the B.I.A. principle (bioelectric impedance
analysis). This enables the measurement of physical relationships within
seconds by means of an undetectable, completely harmless
electric current. The body fat percentage and other physical relationships
in the body can be determined by measuring the electrical resistance
(impedance) and calculating constants and individual parameters such as
age, height, gender and degree of activity.
Muscle tissue and water have good electrical conductivity, and therefore
lower resistance. Bones and fatty tissue, on the other hand, have low
conductivity as fat cells and bones conduct hardly any current as a result
of their very high resistance.
Please be aware that values obtained from the diagnostic scale represent
only an approximation of actual analytical medical data. Only a specialist
doctor can establish the exact amount of body fat, body water,
muscle percentage and bone mass using medical methods (e.g. computed
tomography).
General tips
• If possible, always weigh yourself at the same time of day (preferably in
the morning), after using the toilet, on an empty stomach and unclothed,
in order to achieve comparable results.
• Important for the measurement: only measure body fat when barefoot
and with the soles of the feet slightly moist. Completely dry soles can
result in unsatisfactory measurements due to inadequate conductivity.
• Remain standing and still during the measurement and distribute your
weight evenly over both legs.
• Wait a few hours after unaccustomed physical activity.
• Wait approx. 15 minutes after getting up in the morning to allow the water
in the body to distribute.
• Remember that only long-term trends are important. Short-term changes
in weight within a few days are usually caused by a loss of luid. Body
water plays an important role towards our general wellbeing.
