•  On delivery, the scale is set to “cm” and “kg”. At the back of the scales is a switch with which you can 

switch between “inches”, “pounds” and “stones” (lb, st.).

•  Place the scale on a firm level floor; a firm floor covering is required for correct measurement.
•  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.

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 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 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).
