2 Basic Information (General)

These body fat balance are designed for the determination of body fat, water content,
muscle ratio and bone weight according to the so-called impedance method.
This method is applied to determine the resistance value of the human body with the
help of electrical impulses. A high fat ratio in the body will for instance increase the
resistance value.
For individual calculations, it is possible to store basic data (such as body height, age
and gender) for up to 10 persons.

These balance are only designed to deliver reliable values for persons aged 10 – 80
and a body height of 100 - 220 cm. In order to obtain exact results it is recommended
to step on the weighing plate lightly clad, whilst for the analysis of body components it
is essential to be barefoot.

These balance should not be used by persons requiring a cardiac
pacemaker, a respirator or other devices.

2.1 Proper use

These balance are designed for the determination of weight (in kg/lb), body fat ratio (
in % ), body water ratio ( in % ), muscle ratio ( in % ) and bone weight ( in kg ) of
persons in a private domain. Utilisation of this balance in the medical field is not
permissible.
The weighing process requires that the person steps on the weighing plate barefoot,
with one foot at a time on the 6 metal platelets. Once a stable weighing value has
been reached the weighing value can be read, followed by the other measured
values. .

2.2 Improper Use

Do not use balance for dynamic weighings. In the event that small quantities are
removed or added to the material to be weighed, incorrect weighing results can be
displayed due to the “stability compensation“ in the balance. (Example: Slowly
draining fluids from a container on the balance. )
Do not leave permanent load on the weighing plate. This may damage the measuring
system.
Take care to avoid impacts and overloading of balance above the specified maximum
load (max) under all circumstances. This could cause damage to the balance.
Never operate balance in explosive environment. The serial version is not explosion
protected.
The structure of the balance may not be modified. This may lead to incorrect
weighing results, safety-related faults and destruction of the balance.
The balance may only be used according to the described conditions. Other areas of
use must be released by KERN in writing.
