Abstract
PURPOSE: To make a decision instantaneously by a method wherein AND of a relay contact operating correspondingly to test number is taken, and that of being encoded is fed back to a digital display or an electronic computer to indication on two displays of completion and incompletion of a testing circuit configuration.
CONSTITUTION: AND circuits AND1WAND6 take AND of relays 3AW3H operating correspondingly to test number. Outputs of these AND circuits AND1WAND6 are encoded on an encoder 5, and its output is indicated on a digital display 6. Then, the output of the encoder 5 is fed back to an electronic computer 1 to collation with the commanded test number, which is indicated on two displays of completion and incompletion of a testing circuit configuration, thereby deciding whether or not an operation of the relay corresponding to the test number is correct.
