PURPOSE:To promptly display a screen of a page showing a waveform at a predetermined time when observed waveforms are displayed on the screen to see a minute change of the waveform at the time. CONSTITUTION:A user displays a target waveform on a screen of a display device 21 and scrolls the screen right or left through a keyboard. At this time, a head address of a waveform data memory 13 storing waveform data at a predetermined display position is displayed at the display device 21. The user inputs the head address from the keyboard 19 of an operating part 5. As a result, the head address displayed at the display device 21 is stored in a RAM 18. When the waveform of the head address is to be displayed, the user manipulates the keyboard 19 of the operating part 5 again, so that the waveform is displayed on the screen of the display device 21. |
