Information - Beurer BF 850 Instructions For Use Manual

• Repairs must only be carried out by Beurer Customer Services or authorised retailers. Before
making a claim, please check the batteries first and replace them if necessary.
Storage and maintenance
The accuracy of the measurements and service life of the device depend on its careful handling:
IMPORTANT
• Do not place any objects on the scale when not in use.
• Protect the device from knocks, damp, dust, chemicals, marked temperature fluctuations and
nearby sources of heat (ovens, heaters).
• Do not press the buttons violently or with pointed objects.
• Do not expose the scale to high temperatures or strong electromagnetic fields.

4. Information

The measurement 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
• As far as possible, weigh yourself at the same time everyday (ideally in the morning), after having been
to the toilet, on an empty stomach and without clothing, in order to obtain results which can be com-
pared.
• Important point regarding the measurement: the calculation of body fat may only be made when bare-
foot; the soles of the feet may be lightly dampened where appropriate.
Results may be unsatisfactory if the soles of the feet are completely dry or feature high levels of horny
skin as this results in insufficient conductivity.
Note: There must be no skin contact between your feet, legs, calves or thighs. Otherwise, the
measurement cannot be taken correctly.
• Stand up straight and still whilst weighing yourself.
• Wait a few hours after any physical exertion to which your body is unaccustomed.
• Wait approx. 15 minutes after getting up so that the water stored in the body can disperse.
• You must remember that only the long-term trend is important. Brief deviations in weight within a few
days are normally caused by loss of fluids; however, body water plays an important role in terms of
well-being.
Limitations
When calculating the body fat and the additional values, deviating and implausible results may occur in
the case of:
• Children under 10 years of age,
• Performance athletes and body-builders,
• Persons with a fever, persons undergoing dialysis, persons demonstrating oedema symptoms and per-
sons suffering from osteoporosis,
• Persons taking cardiovascular medicine (affecting the heart and vascular system),
• Persons taking vasodilative or vasoconstrictive medication,
• Persons with significant anatomical deviations in their legs compared with their overall body height (leg
length significantly shorter or longer).
