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 (2 x 3 V Lithium-Batterie CR 2032). 

5. Operation

5.1 Weight measurement

Place the scale on a firm level floor (no carpet); a firm floor covering is re-
quired for correct measurement. Press quickly and forcefully with your foot 
on the platform of your scale!

The entire display (Fig 1) appears up to “

0.0

” (Fig. 2) as a self-test (tap-on technology).

Now the scale is ready to measure your weight. 
Stand on the scale without moving about and distribute your weight evenly on both 
legs. The scale immediately begins to measure your weight (Fig. 3). 
The scale switches off 10 seconds after you step down from it. The measuring re-
sult remains visible during this time.

Make sure that you always switch on the scale first and wait for the display “

0.0

” 

(Fig. 2) before stepping on.
