Patent attributes
The present invention provides a data-processing system for measurement devices, which performs a step-by-step sequence of data-processing tasks. In a conventional data-processing system, a failure in one data-processing task also causes the subsequent tasks to be unsuccessful. In such a case, the conventional data-processing system indicates the result of each unsuccessful task or the final result of the analysis by displaying only a blank or a specific character (e.g. the digit “0”). From such simple information, users cannot immediately identify the cause of the error. In contrast, in the data-processing system according to the present invention, if a data-processing task has been incorrectly performed for some reason, an error detector detects the error, and an error investigator identifies the cause of the error. Then, an error message displayer prepares an error message indicating the reason why the data-processing task concerned was unsuccessful and then displays the error message as the result of each of the aforementioned task and the subsequent tasks. The user can immediately learn the cause of the error by checking the error message of any of the unsuccessful tasks. Thus, the problem can be identified and solved in a shorter period of time.
