SELECTIVE DISPLAY DEVICE FOR BALANCING WEIGHT FOR CORRECTING UNBALANCE QUANTITY

摘要

PURPOSE:To make measurement speedy and easy by switching storage devices electively according to variation in the rank width of correction weight and displaying selectively balacing weights for correction in a group of plural balancing weights. CONSTITUTION:An unbalance quantity detector 1 detects the quantity of unbalance, which is digitized by an A/D converter 2 and stored in a storage device 3. The rank width of the correction weight of the storage device 3 is so determined that, for example, ROMs 3a, 3b, and 3c correspond to intervals of 5g, 3g, and 1g. A proper ROM is selected with a changeover switch 4 and a signal corresponding to correction width is generated by the selected ROM to display 6 a balancing weight for correction through a decoder 5. For example, when the quantity of unbalance is 18g and the switch is placed at the side of the ROM3a (5g interval), a correction weight of 17.25-22.5g is displayed. Thus, the balancing weight for correction is displayed immediately, so measurement is performed precisely and speedily.
