PROBLEM TO BE SOLVED: To display a noticeable wave-form on the frontmost surface by a simple operation to improve discrimination property of the noticeable wave-form by providing a wave-form select button displaying an optional waveform as a noticeable wave-form on the frontmost surface on one part of a measured wave-form display image plane. SOLUTION: A display image plane is divided in the lateral direction into a wave- form display territory A and an operation territory B, 12 pieces of display bars J corresponding to measured wave-forms are arranged on the center part of the operation territory B at equal intervals in the lateral direction with the same colors as the display colors of respective measured wave-forms, and the lower parts are provided with wave-form select buttons K respectively corresponding to the respective bars J. The wave-form select button K individually controls ON/OFF according to the select motion while making display of a measured wave-form in the wave-form display territory A and display of the display bar J in the operation territory B into one set. For example, when the noticeable wave-form is set No.1, a mouth cursor is positioned on a part of the corresponding display bar J, and it is clicked, the measured wave-form of the channel No.1 is displayed on the frontmost surface, and the amplitude scale D and the alarm display bar I are displayed.
