title: [Trial digitalization of analog-data obtained from the AutoAnalyzer].
abstract: The AutoAnalzer(Basic Model) manufactured on Technicon corporation was a very useful instrument for clinical laboratory automation, but it was necessary to convert the data obtained from the instrument to digital values used the chart reader. This was very troublesome and there was apprehension that there would be errors in A-D conversion. We tried converting data obtained from the AutoAnalzer to a digital value by on-line connection of the instruments with minicomputers(LINC-8 and FACOM-R). The output of the recorder was converted to voltage(0 to 100 V) using a potentiometer, quantitated(0 to 1.000) by the A-D converter attached to LINC-8, and processed by the minicomputer. The control-box was an experimental device mainly designed for the convenience of users. The functions of the control-box were designated analytical items, No. of A-D converters, start and stop of the AutoAnalzer operation to the minicomputer. Employing the control-box, a technician operated this system freely, without direct computer operation. We established a generally satisfactory system for clinical laboratory automation using the minicomputer.
