572/573/KB/DS/FKB/FCB/KBJ-BA-e-1370223 Fundamental information (general)It is essential to read through and observe the complete operating instructions before in-stalling and commissioning.3.1 Intended useThe balance you have acquired serves to determine the weighing value of the material tobe weighed. It is intended to be used as a “non-automatic“ balance, i.e. the material to beweighed is manually and carefully placed in the centre of the weighing plate. The weighingvalue can be read off after a stable weighing value has been obtained.3.2 Inappropriate useDo not use the balance for dynamic weighing. In the event that small quantities are re-moved or added to the material to be weighed, incorrect weighing results can be displayeddue to the “stability compensation“ in the balance. (Example: Slowly draining fluids from acontainer on the balance.)Do not leave a permanent load on the weighing plate. This can damage the measuringequipment.Be sure to avoid impact shock and overloading the balance in excess of the prescribedmaximum load rating (max.), minus any possible tare weight that is already present. Thiscould 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 weighingresults, 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 areasof 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 weight mustbe checked at regular intervals within the scope of quality assurance. For this purpose, theanswerable user must define a suitable interval as well as the nature and scope of thischeck. Information is available on KERN’s home page (www.kern-sohn.com) with regardto the monitoring of balance test substances and the test weights required for this. Testweights and balances can be adjusted quickly and at a reasonable price in KERN’s ac-credited DKD calibration laboratory (return to national normal).
