46 CFS/CCS-BA-e-122011.2 Numeric input of the average piece weightSet reference Input known average unit weight with numerical keys and confirm within 5 secs.with or (CFS 50K-3 models).If in the weight display as weighing unit [kg] is active, the average piece weightwill be displayed in [g]. If as weighing unit [lb] is active, the average piece weightis also displayed in [lb].Count the items Tare if necessary, place weighing good and read off the number of items.When an optional printer is connected, the displayed value can be edited bypressing (menu settings „P mode“ „Print“ „Au OFF“, chap. 13.2).Delete unit weight Press11.3 Automatic reference optimizationIf at the reference determination the placed weight or the placed piece number istoo small, in the display of the average piece weight the triangle symbol will appearover [ ] or [ ].To optimize the calculated average piece weight automatically, add further partswhose number is smaller than that of the first reference determination. After thereference optimization sounds a signal tone. For each reference optimization theaverage piece weight is newly calculated. As the additional pieces increase thebase for the calculation, the reference also becomes more exact.By pressing or (CFS 50K-3 models) recalculation can be avoided andthus the reference weight locked.Automatic reference optimization will be deactivated as soon as the number ofadded parts exceeds the saved reference quantity.
