PURPOSE:To execute the observation in a state that plural signals are stationary by time series on the picture, by displaying a desired signal by time series on the picture of a CRT whenever a state is varied, and making the picture of the CRT stand still by a refresh inhibiting signal. CONSTITUTION:From a CRT7 provided with a keyboard, a display signal name, a display start signal name and a display refresh inhibiting signal name are registered and stored in a memory 6. From the CRT7, a signal of time series display is inputted. This signal is inputted to a display switching part 52 of a muCPU5, displays a picture of the CRT by time series, and the switching part 52 starts to display a signal of the registered display start signal name from a sequence information part 4. A state variation detecting part 53 sends a state variation signal to the switching part 52 when a signal of the display signal name has been varied. The switching part 52 receives this signal and displays the display signal on the CRT. When a refresh inhibiting signal is detected by polling from the sequence display part 4, the switching part 52 stops updating the CRT. |
