• Repairs may only be carried out by customer service or authorized dealers. Before submitting any
complaint, first check the batteries and replace them if necessary.
• All scales comply with EC Directive 89/336 + supplements. Should you have any questions
concerning the use of our scale, please contact your dealer or customer service.
2. Information on the diagnostic scale
The measuring principle of the diagnostic scale
This scale operates according to the B.I.A. principle (bioelectric impedance analysis). This enables
physical relationships to be measured 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 the inclusion in a calculation
of constants and individual parameters (age, height, gender, 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 toilet, on an empty stomach and unclothed, in order to achieve comparable results.
– Important for the measurement: body fat can only be measured 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 during the measurement.
– Wait a few hours after unaccustomed strenuous activity.
– Wait approx. 15 minutes after getting up in the morning to allow the water in the body to
distribute.
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,
– 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).
3. Batteries
If provided, pull out the battery insulating strip at the battery compartment or remove the protective
film from the battery and insert the battery with the correct polarity. If the scale fails to operate,
remove the battery completely and reinsert it.
