An acoustic signal sounds.
Step onto the scales and stand still until the bar
graph on the display stops moving. Distribute
your weight evenly on both legs.
Note: Stand on the scales with bare feet only.

Then the scales determine the percentage of
body fat and body water as well as bone and
muscle mass and the recommendation for the
daily calorific intake. Meanwhile flashes on the

- the body water content as % and weight
in kg,
- the bone mass and muscle mass in kg,
- the current weight in kg as well as an
approximate value for the daily calorific
intake to maintain this weight (PC Present
Calorie is displayed instead of age),
- the optimum weight in kg as well as an
approximate value for the daily calorific
intake to maintain this weight (OC Optimum
Calorie is displayed instead of age),

Note:
- The scales determine an approximate value
for the optimum weight and the associated
calorific number based on the input and
calculated data (age, height, body fat, activi
ty level, ...) in order to maintain this weight.
To determine the ideal personal calorific inta
ke, we recommend that you consult your
doctor or nutritionist,

indicates the graphical analysis allocated to
the particular measurement.

Important: Stand with feet, calves and thighs
apart, otherwise the measurement will be incor

The scales automatically switch off a couple
of seconds after the end of the measuring
process.
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.
