What does BMI mean?
The Body Mass Index (BMI) is a measured value
for evaluating the weight of a person.
The value can be used to determine whether
the person is normal weight, overweight
or underweight.
The Body Mass Index (BMI) is the quotient
of your weight (kg) and the square of your
height (m). The unit of the BMI is kg/m².
Meaning of BMI (according to WHO)

The Body Mass Index is a very approximate
value only.
How does body fat measurement
function?
Body fat is measured according to the BIA
principle (bioelectrical impedance analysis).
The appliance transmits a weak, harmless
electrical signal through the body.
The resistance (impedance), i.e. the signal
which the body resists, is measured.
The resistance is affected by the composition
of the human body.
Muscles and organs contain water and are
therefore good conductors. Fat resists the
signal and is therefore a poor conductor.
The body fat percentage is calculated from
this measured resistance taking into account
the data (size, age, sex) which was input into
the scales.
The body fat content varies greatly from person
to person. Therefore, only approximate values
are indicated in the following table.

Water measured values
The body fat and water measurements are
influenced by the amount of water in the body.
The amount of water varies, e.g. accordingto
the time of day, demands on the body, baths
or showers, menstruation, eating and drinking.
Even illnesses or medication may influence
the result.
The following guide values, according to WHO,
apply to persons who are normal weight:
–
–
Cleaning the appliance
Never immerse the scales in water.
Do not use a steam cleaner.

Wipe the scales with a damp cloth, do not
use scouring agents.
Clean the glass surface with a standard
glass cleaner.
The calibration was defective.
Remove and re-insert the battery.
Then tap briefly and audibly on the surface
of the scales with the ball of your foot.
The weighing process was not conducted
with the person standing still or for long
enough.
You must stand still on the
scales for at least five seconds.
