Page 6: Fundamental Information (General)
3 Fundamental information (general) 3.1 Designated 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. -
Page 7: Monitoring The Test Substances
3.4 Monitoring the test substances The metrology features of the balance and any possible available adjusting weight must be checked at regular intervals within the scope of quality assurance. For this purpose, the answerable user must define a suitable interval as well as the nature and scope of this check. -
Page 8: Unpacking, Installation And Commissioning
6 Unpacking, installation and commissioning 6.1 Installation Site, Location of Use The balance is constructed in such a way that reliable weighing results can be achieved under normal application conditions. By selecting the correct location for your balance, you will be able to work quickly and precisely. -
