•  The scale should be cleaned occasionally with a damp cloth. Do not use abrasive detergents and never 

immerse the scale in water.

•  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.

•  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. 

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  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 mea-
suring 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 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 in adequate 
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 bat-
tery completely and reinsert it.
