4 Basic Information (General)
4.1 Proper use
These scales are used to determine weight of people sitting at rest,
The person should be weighed carefully and have contact with the center of the seat,
sit and stay calm.
As soon as a stable weighing value is reached the weighing value can be read.
The scales are designed for long-term usage.
Determination of the body weight.
Use as „non-standalone weighing scale“, that is, a person sits carefully onto the
seating surface’s centre. Once a steady display value is shown, you can read the
weight value.
The instruments shall only be used by people who can sit still.
The balances should be checked for correct condition prior to each utilisation by a
person familiar with proper operation of the balance.
