Abstract

PURPOSE:To easily edit and store the logging data with no intervention of a recording medium by outputting the logging data to an external data processor connected to an external data output communication terminal via this terminal. CONSTITUTION:A changeover switch 62 switches the destination of a data transmission connector of an RS-232C serving as an external output communication terminal to the connector placed at the side of an external data processor in a state where a note type personal computer 10, i.e., the external data processor is loaded in the device main body part. In a data collection mode, a system control unit 41 reads the measurement data on the equipments 49-52 and 57-60 which are connected to the terminal controllers 45-48 and 53-56 respectively. Then the unit 41 accumulates these read measurement data and stores them as the logging data. Thus the logging data can be easily edited and stored with no intervention of a floppy disk, etc., and also the data can be sent to a device which edits and stores the logging data without discontinuing the original operation of a data logging device.
