7 Information
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 elec-
tric 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 activ-
ity.
Muscle tissue and water have good electri-
cal conductivity, and therefore lower resis-
tance. Bones and fatty tissue, on the other
hand, have low conductivity as fat cells and
bones conduct hardly any current as a re-
sult of their very high resistance.
Please be aware that values obtained from
the diagnostic scale represent only an ap-
proximation of actual analytical medical da-
ta. Only a specialist physician can accu-
rately determine body fat, body water,
muscle percentage and bone structure us-
ing medical procedures (e.g. computed to-
mography).
General tips
x
If possible, always weigh yourself at the
same time of day (preferably in the mor-
ning), after using the toilet, on an empty
stomach and unclothed, in order to
achieve comparable results.
x
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 unsat-
isfactory measurements due to inade-
quate conductivity.
x
Stand still and upright during the meas-
urement.
x
Wait a few hours after unaccustomed
physical activity.
x
Wait approx. 15 minutes after getting up
in the morning to allow the water in the
body to distribute.
x
Remember that only long-term trends
are important. Short-term changes in
weight within a few days are usually
caused by a loss of fluid. Body water
plays an important role towards our ge-
neral wellbeing.
Limitations
When measuring body fat and other values,
deviating and implausible results may occur
in:
x
children under approx. 10 years,
x
competitive athletes and body builders,
x
pregnant women,
x
persons with fever, undergoing dialysis
treatment or with symptoms of edema or
osteoporosis,
x
persons taking cardiovascular medica-
tion (affecting the heart and vascular
system),
x
persons taking vascular dilating or vas-
cular constricting medication,
x
persons with considerable anatomic de-
viations of the legs in relation to total
body size (length of the legs considera-
bly shortened or lengthened).
