Abstract
PURPOSE: To achieve the improvement in the accuracy of ripple adjustment without any observing device by reading the analog input signal directly into a memory unit, judging the same by the program of a CPU unit and displaying the results of the judgment.
CONSTITUTION: The difference E of the maximum value MAX and minimum value MIN of analog input waveform is taken and whether it is within a permissible value EO or not is jueged by the program of a CPU unit 6 and is announced to the operator. When the ripple value E is still higher than the permissible value EO, a lamp 10 is put ON and when the ripple value becomes lower than the permissible value EO, the lamp 10 is put OFF. The operator adjusts a volume control 2 for adjustment while viewing the lamp 10. If at this time the adjustment is made in the direction of decreasing the ripple valve E, the lamp 11 goes OFF and if converse, the lamp 11 goes ON. In this way, the ripple value may be adjusted to a minimum without requiring any observing device such as synchroscope.
