EFB-BA-e-0411 53 Fundamental information (general)3.1 Intended useThe 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. thematerial to be weighed is manually and carefully placed in the centre of the weighingplate. The weighing value can be read off after a stable weighing value has been ob-tained.3.2 Inappropriate useDo not use the balance for dynamic weighing. In the event that small quantities areremoved or added to the material to be weighed, incorrect weighing results can bedisplayed 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 alreadypresent. 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 incorrectweighing results, faults concerning safety regulations as well as to destruction of thebalance.The balance may only be used in compliance with the described guidelines. Varyingareas of application/planned use must be approved by KERN in writing.3.3 GuaranteeThe guarantee is not valid following- non-observation of our guidelines in the operating instructions- use outside the described applications- alteration to or opening of the device- mechanical damage and damage caused by media, liquids- natural wear and tear- inappropriate erection or electric installation- overloading of the measuring equipment3.4 Monitoring the test substancesThe metrology features of the balance and any possible available adjusting weightmust be checked at regular intervals within the scope of quality assurance. For thispurpose, the answerable user must define a suitable interval as well as the natureand scope of this check. Information is available on KERN’s home page (www.kern-sohn.com) with regard to the monitoring of balance test substances and the testweights required for this. Test weights and balances can be adjusted quickly and ata reasonable price in KERN’s accredited DKD calibration laboratory (return to na-tional normal).
