PURPOSE:To avoid a mistaken discrimination, by increasing the brightness of the relevant display element that other display elements in case when the weight display overlaps the allowance upper and lower limit value display or the deviation display overlaps the allowance upper and lower limit deviation display. CONSTITUTION:The weighing signal is sent to the control part 6 from the weight detecting part 2 via an A/D converter 4, and at the same time the allowance upper and lower limit values are sent from the keyboard part 8. Thus the part 6 converts these signal and values into a rate to the weighing. The display signal is supplied to the digit signal driver 12 and segment signal driver 14 with a synchronism secured with the counter output of part 6, and the real weight of an article is displayed through the figure display tube 18. At the same time, the bar graph display tube 16 glows. In this case, if the segment displaying the allowance upper and lower limit value rate of pilot lamp row overlaps the segment displaying the weight rate, the duty ratio of the glowing control pulse increases. Thus these segments becomes brighter than other segments to avoid a mistaken discrimination. |
