• Ensure that no liquid gets on the scale. Never dip the scale into water. Never wash it under run-
ning water.
• Do not place any objects on the scale when it is not being used.
• Protect the unit against hard knocks, moisture, dust, chemicals, major temperature fluctuations
and heat sources which are too close (stoves, heating radiators).
• Do not press the buttons using excessive force or with pointed objects.
• Do not expose the scale to high temperatures or strong electromagnetic fields (e.g. mobile phones).
4. Information
The measuring principle
This scale works on the principle of B.I.A. (bioelectrical impedance analysis). This involves the calculation
of body content within seconds, using a current that is not noticeable, is completely non-hazardous and
does not pose any risk.
When this measurement of the electrical resistance (impedance) is considered alongside constants and/
or individual values (age, height, gender, activity level), the body fat percentage and other variables in
the body can be calculated. Muscle tissue and water conduct electricity well and therefore have a lower
resistance. In contrast, bones and fat tissue have low conductivity as the fat cells and bones are barely
able to conduct the current due to very high levels of resistance.
Please note that the values calculated by the diagnostic scale only represent an approximation of the
actual medical analytical values for the body. Only a specialist doctor can precisely establish the body fat,
body water, muscle percentage and bone structure using medical methods (e.g. computer tomography).
General tips
• If possible, always weigh yourself at the same time of day (preferably in the morning), after using the toi-
let, 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.
• Stand still and upright during the measurement.
• 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 fluid. Body water plays an important role towards our general wellbeing.
Limitations
When measuring body fat and other values, deviating and implausible results may occur in:
• children under approx. 10 years,
• competitive athletes and body builders,
• pregnant women,
• persons with fever, undergoing dialysis treatment or with symptoms of edema or osteoporosis,
• persons taking cardiovascular medication (affecting the heart and vascular system),
• persons taking vascular dilating or vascular constricting medication,
• persons with considerable anatomic deviations of the legs in relation to total body size (length of the
legs considerably shortened or lengthened).
