3 Fundamental information (general)

3.1 Intended Use

The balance you have acquired serves to determine the weighing value of the
material to be weighed. It is intended to be used as a "non-automatic" balance, i.e.
the material to be weighed is manually and carefully placed in the centre of the
weighing plate. The weighing value can be read off after a stable weighing value has
been obtained.

3.2 Inappropriate use

Do not use the balance for dynamic weighing. 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 a permanent load on the weighing plate. This can damage the
measuring system.
Be sure to avoid impact shock and overloading the balance in excess of the
prescribed maximum load rating (max.), minus any possible tare weight that is
already present. This could cause damage to the balance.
Never operate the balance in hazardous locations. The series design is not
explosion-proof.
Structural alterations may not be made to the balance. This can lead to incorrect
weighing results, faults concerning safety regulations as well as to destruction of the
balance.
The balance may only be used in compliance with the described guidelines. Varying
areas of application/planned use must be approved by KERN in writing.
