PURPOSE:To prevent reading errors of displays in the stage of changing over display units by providing means of announcing the min. graduation in said converted unit to the user. CONSTITUTION:A load detector 11 which converts the load W applied upon a weighing pan 11 to a digital signal outputs the data indicating the magnitude of the load at every specified time interval. The data inputted at every specified interval is stored successively in an RAM23 and when the new data is inputted, the oldest data is pushed out and discarded. A display 3 which displays the contents of the display register in a CPU displays respective units in combination. A key group marked with ''g'', ''pound'', ''pwt'', ''ct'', ''moisture %'', and ''ratio %'' and an operating switch for subtraction of tare, etc. are provided as conversion keys for indicating conversion on a keyboard 5. |
