Beurer BG 55 - Manual (Page 11)

• 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).
