• Protect the scale against hard knocks, moisture, dust, chemicals, major temperature fluctuations and
heat sources which are too close (stove, heating radiators).
• Repairs may only be carried out by Beurer customer service or authorized dealers. Before submitting
any complaint, first check the batteries and replace them if necessary.
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).
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: 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. 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.
Your scale is provided with a “Change battery” indicator. If the scale is operating with a battery which is
too weak, “
Lo
” appears on the display and the scale will switch off automatically. In this case, the battery
must be exchanged (1 x 3 V lithium battery CR2032).
5. Operation
5.1 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.
