General notes

• The unit is for personal use only and is not intended for medical or commercial applications.

• Please note that technically related measuring tolerances are possible, as the scale is not calibrated for

professional medical applications.

• Ages 10 ... 100 years and height settings from 100 ... 220 cm (3-03”–7-03”) can be preset. Load capaci-

ty: max. 150 kg (330 lb, 24 st). Result in steps of 100g (0.2 lb, 1 lb). Measurements of body fat, body wa-

ter and muscle density in steps of 0.1%.

• Calorie requirement is indicated in steps of 1 kcal. The BMI value (body mass index) is shown in incre-

ments of 0.1.

• When supplied to the customer, the scale is set to weigh and measure in „kg“ and „cm“. To the rear of

the scale in the battery compartment, there is a switch with which you can select ‚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 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).

The BMI is calculated using the height value entered and the measured weight value.

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).
