Information On The Diagnostic Scale; Weight Measurement - Beurer BG 51 XXL Mode D'emploi

• 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 elec-
tric 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 indi-
vidual 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).
4. Batteries
If present, pull the battery insulating strip off the battery compartment cover or remove the battery's pro-
tective film and insert the battery according to the polarity. If the scale fails to operate, remove the battery
completely and insert it again. Your scale is equipped with a "replace battery" indicator. When the scale
is operated with a battery which is too weak, "L0" appears in the display field and the scale automatically
switches off. The battery must be replaced in this case (4 x 1.5 V battery AAA).
5. Operation

5.1 Weight measurement

Step onto the scale. Stand still with your weight distributed equally on both feet. The scale begins to take
measurements straight away. After flashing twice, the weight is established.
If you step off the weighing area, the scale switches off after a few seconds.
