Abstract: PURPOSE:To display and store data even if there is a sudden change caused in a sampling time by storing temporarily data in a 2nd sampling time period, and displaying and storing data of N times when the maximum level variation is larger than a specific value. CONSTITUTION:A CPU3 stores input data temporarily at intervals of a 1st sampling time. Then when the 1st sampling time is elapsed N times, namely, when the 2nd sampling time period is elapsed, the maximum level variation of the temporarily stored data is extracted. Then it is decided whether or not the maximum level is larger than a specific value and when not, it is judged that the data does not vary and only one data is displayed and stored in the 2nd sampling time. When the maximum level variation is larger than the specific value, on the other hand, the temporarily stored data are all displayed on a CRT display device 5 and stored. Consequently, a sudden change occurring in the 2nd sampling time is displayed and stored without being overlooked.
