3. 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 physi-
cal 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 in-
dividual parameters (age, height, gender, degree of activity).
Please be aware that values obtained from the diagnostic scale represent only an approximation of actual
analytical medical data.
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: 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).
4. Operation
The scale is solarpowered. It requires sufficient light to operate. If the lighting
conditions are sufficient, a flashing sun symbol or “ 0.0” appears in the display.
If the lighting conditions are too dark, no measurement can be taken. Place the
scale somewhere with more light.
4.1 Weight measurement
Place the scale on a firm level floor (no carpet); a firm floor covering is required for correct measure-
ment.
Step on the scale. It immediately begins to measure. Stand still with your weight distributed equally on both
legs. If the display appears continuously, the measurement has finished.
If you step off the weighing area, the scale switches off after a few seconds.
4.2 Setting user data
To measure your body fat percentage and other physical data, you must enter your personal user parame-
ters.
The scale has 10 memory positions in which you and other members of your family can save and recall
personal settings.
Switch on the scale (tap the weighing area). Wait until the display shows “ 0.0”.
