Method for qualifying timer to analog display in stop-watch, involves classifying timer in accuracy class among finite number of predefined accuracy classes based on assessment of measurement accuracy of time interval

摘要

The method involves measuring, by a timer, an interval of time having a predetermined duration (40), and assessing the accuracy of the measurement (50). The timer is classified (60) in an accuracy class among a finite number of predefined accuracy classes based on the assessment, and the timer is classified (70) in an accuracy category among a finite number of predefined accuracy categories. The timer is classified in the accuracy class by determining a grade of the timer, where the grade is determined according to a highest relative tolerance followed by the timer during the duration. An independent claim is also included for a device for qualifying a timer to an analog display.
