3 Fundamental information (general)
3.1 Intended use
The balance you have acquired serves to determine the weighing value of the mate-
rial 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 ob-
tained.
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 drain-
ing fluids from a container on the balance.)
Do not leave a permanent load on the weighing plate. This can damage the measur-
ing equipment.
Be sure to avoid impact shock and overloading the balance in excess of the pre-
scribed 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 explo-
sion-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.
3.3 Protective measures
The moisture analyser of Safety Class 1 may only be connected through a carefully
installed socket with protective earth (PE). The protective effect must not be can-
celled out by the use of an extension lead without earth wire. For power supplies from
mains not provided with a protective earth, an equivalent protection meeting the valid
installation regulations must be provided by a qualified electrician.
3.4 Warning
Individual parts of the housing (e.g. ventilation grille ...) can become very hot during
operation. Avoid touching the apparatus except by the handles provided for this pur-
pose.
Sample materials which produce corrosive vapours (e.g. acids) can cause problems
of corrosion of components. The MLB50-3 should be used primarily for drying hy-
drous substances.
The MLB50-3 must not be used to analyse highly inflammable samples which pre-
sent an explosion hazard.
