PURPOSE:To avoid computation errors and to improve working efficiency, by obtaining the quality control data from the outputs of length measuring means, and continuously preparing control charts by a table preparing device. CONSTITUTION:A digital display type length measuring system is composed of micrometers 1A and 1B as two length measuring means and a data processing device 2 as a data processing means, which sequentially receives the measured length data from the micrometers 1A and 1B and obtains the quality control data and the like from the received inputted length data. The data processing means 2 has an operating circuit, which obtains the quality control data from the output data of the micrometers 1A and 1B. The quality control data are outputted as continuous control charts from a printer 33 as a table preparing device. |
