Gravimetric Test. Such instruments are equipped with parts that can move with
great force and at considerable speed. Moreover, these instruments often handle
toxic or other chemically and biologically hazardous substances which require
adequate safety measures.
As a consequence, the safety of users and personnel can only be ensured if the
safety instructions in this manual and the relevant hardware and software
manuals of the instruments on which the Gravimetric Test is run, are strictly
observed and followed.
Therefore, the relevant manuals must always be available to all persons
performing the tasks described herein.
2.1 User Qualification

etc.), must be qualified and trained to install and use the Balance Kit for the
Gravimetric Test.
In particular, users must fulfill the following qualifications:
They must have a thorough knowledge of the application run on the system.
They must be familiar with the good laboratory practice guidelines.
