General Notes; Information On The Diagnostic Scale - Beurer BG 51 XXL Manual De Instrucciones

•
Risk of explosion! Never throw batteries into a fire.
•
Do not charge or short-circuit batteries.
•
If the device is not to be used for a long period, take the batteries out of the battery compartment.
•
Use identical or equivalent battery types only.
•
Always replace all batteries at the same time.
•
Do not use rechargeable batteries.
•
Do not disassemble, split or crush the batteries.

2.2 General notes

• Not intended for medical or commercial use.
• Please note that measuring tolerances are possible due to technical reasons because the scale has not been
calibrated.
• Ages 10 ... 100 years and height settings from 80 ... 220 cm (2'7" – 7'2") can be preset. Load capacity:
max. 200 kg (441 lb, 31 St). Result in steps of 100 g (0.2 lb, 1 lb). Measurements of body fat, body water
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". You can switch
to "pounds" (lb) and "stones" (st:lb) by switching on the scale and immediately pressing the "down"
button until the desired unit is shown on the display.
• 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 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,
