PURPOSE:To reduce recording failure due to excess and deficient deflecting width of a signal to be recorded, and to improve reliability, by a method wherein transient phenomenon signals are converted into a digital amount, and when the results are recorded by a plotter, they, simultaneously, are stored in a memory device. CONSTITUTION:Transient phenomenon signals Sa-Sn, which are sent from terminals 11a-11n and change every moment, are converted into a digital amount by means of an A/D converter 12, and the results are sent to a recorder 14 by means of a data controller 13 for storage. Simultaneously, after data are converted into signals for high-speed plotter, they are sent to a plotter 16 via a changing-over 15, and are plotted on a record sheet 17. Meanwhile, the changing-over device 15 is switched to a memory device (14) side for connection, and recorded data are graphed with the high-speed plotter 16 actuated. This permits the conformation of a deflecting width of a signal in a record sheet to a size of a sheet through just adjustment of a parameter for exchanging plotting data, and enables to perform a rerecording operation even if failing in recording. |
