Adding weight
The weighed object must weigh more than 2 kg. If you want to  nd e.g. the weight of your baby, weigh yourself
 rst (wait until the numbers stabilize), then without stepping o the scale, take the baby in your arms. The
numbers start  ashing, then they stabilize and the resulting weight stabilizes. Subtracting your own weight
from the newly obtained value will give you the weight of your child.

Measurement of body fat, water, muscle mass, bones and calories
Measurement principles
Through human body pass electric signals of acertain frequency, whereby the impedance of body fat is higher
than the impedance of muscle or other human tissues. The device generates an alternating electrical current
with safe frequency and low voltage. Using the analysis of biological resistance, impeding the passage of the
current through the human body (impedance of various tissues, fats and muscles), the percentage of the body
fat in human organism is derived from the di erences in resistance.
About the percentage of body fat
This index is an indicator of the percentage of body fat in the human body.
The fat content in the body should be maintained around certain level, excess body fat impairs metabolic
processes and thus increases the risk of various diseases.
