storage and maintenance
The accuracy of the measurements and service life of the device depend on its careful handling:
IMPOrTanT
• The unit should be cleaned occasionally. Do not use abrasive detergents and never immerse the
unit in water.
• 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 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 physician can accurately determine body fat, body water, muscle
percentage and bone structure using medical procedures (e.g. computed 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).
