description The invention belongs to the technical field of electronic measuring instruments, and particularly relates to a real-time digital overcurrent protection method and system for a precision source meter, and the method comprises the steps: obtaining an output voltage set value, a voltage measurement value, a current-limiting protection set value and a current measurement value; calculating a deviation value between the output voltage set value and the voltage measurement value and a deviation value between the current-limiting protection set value and the current measurement value; calculating a voltage control increment and a current control increment, and comparing the voltage control increment with the current control increment so as to output the lowest value of the voltage control increment and the current control increment for constant voltage output and current-limiting protection; when the precision source meter outputs at constant voltage, if the working current exceeds the protection current, the const
