5. Initial use
Inserting the batteries
Please remove the battery insulating strips and/or position the batteries correctly with regards to the polar-
ity displayed in the battery compartment (as symbol
). If the scale fails to operate, remove the batteries
completely and reinsert them.
Changing the weight unit
The scale shows the values in kg. On the back of the device, there is a button that you can use to switch
the units between kilograms [kg], pounds [lb] and stone [st].
Setting up the scale
Set up the scale on a level and solid surface.
6. Information
The measuring principle
This scale operates according to the B.I.A. principle (bioelectric impedance analysis). This enables the
measurement of physical relationships 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 calculating constants and individual parameters
such as age, height, gender and 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 re-
sult 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 doctor can establish the exact amount of body fat, body water,
muscle percentage and bone mass using medical methods (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: only measure body fat when barefoot and with the soles of the feet
•
slightly moist. Completely dry soles can result in unsatisfactory measurements due to inadequate
conductivity.
Remain standing and still during the measurement and distribute your weight evenly over both legs.
•
Wait a few hours after unaccustomed physical activity.
•
Wait approx. 15 minutes after getting up in the morning to allow the water in the body to distribute.
•
Remember that only long-term trends are important. Short-term changes in weight within a few days
•
are usually caused by a loss of fl uid. Body water plays an important role towards our general wellbeing.
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,
•
persons with fever, undergoing dialysis treatment or with symptoms of edema or osteoporosis,
•
persons taking cardiovascular medication (a ecting the heart and vascular system),
•
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).
