- The dierence in weight in relation to the previous weighing
The rst indicator of your weight is simply its evolution
over time. Without any eort to remember, your scales
automatically calculate the gain in or loss of weight
since the last time you weighed yourself and an indica-
tor light shows you the extent of this change.
- The Body Mass Index (BMI)
The BMI is a coecient used by nutritionists that in-
volves weight and height. It places individuals in weight
categories recognised by the scientic community. Its
measurement complements that of weight.
- Evaluation of rate of body fat
There is a correlation between bio-electric impedance
(that is, the resistance the human body has to an elec-
trical signal) and the composition of the body mass.
All impedance analyser scales fundamentally oper-
ate according to the same principle which consists in
measuring the bio-electric impedance of the human
body, combining it with the subject’s body type criteria
(height, weight, gender, age) to calculate body fat that
is estimated and based on clinical measurements.
In every case, the evaluation of the body fat by imped-
ance analyser is a method that uses a statistical model
to measure weight and impedance. The principle of
impedance analysis itself does not give the body fat
precisely.
- Evaluation of the hydration rate
Water is the principal component in our bodies. It
plays a vital role in helping the body to remain in good
health. Knowing your hydration rate is thus important.
Just like the fat, the hydration rate is calculated using
the BIA method.
USE
These scales have 2 dierent modes of use:
• “Guest” mode: Use this mode if you only want to check
your weight.
• “User” mode: This mode is the best ally to your gure.
In this mode, each user has his or her own session.
The scales use personal data saved in the memory to
calculate your body mass index and your change in
weight compared to the previous weighing.
