Abstract

PURPOSE: To surely detect a momentary variation of input having scarce reproducibility by a method wherein variation of an input is caught and the operation is self-retained.
CONSTITUTION: When an object contact is momentarily closed, a current through a resistor R1 flows in a comparison input terminal I1 of a comparison unit 1 through the object contact and an input terminal T. And then, the comparison unit 1 operates, and following thereto, an output unit 2 self-retains its operation and an information unit 3 informs that a state variation exists at an input. When measuring whether or not an input signal momentarily exceeds a value corresponding to a set scale of a voltage setting device R5, an input switching switch S2 is placed to the V side and a comparison input switching switch S3 is placed to the A side.
