[en] For the purpose of automating the checking of logic circuits of multichannel wire detectors, a test block was developed which plots test results with an electronic computer. To ensure high reliability, the number of program-controlled entrance channels of the test block was kept at a minimum, and the electronics test was made sequentially (on the block). The test block has 32 program-controlled output channels and 16 entry channels for reading the test results. The block is constructed of integrated microsystem. Methods for finding the minimum number of test combinations are examined. A modification of the White chart for initial introduction of functions of 5 and 6 variables is given. A block diagram of the test block is shown
