The state of the counters is decrypted by the deshators 4 and 5. The decoder 4 is connected to the outputs of the counter 2 and 3, and the decoder 5 to the outputs of the 3.1 + in outputs of the decoder 4 are connected to the points of the tested product 10 and to the analysis unit 6 and the probe ; there is an impulse check

The pulses from the pulse generator 1, controlled by the signal from the output control block 8, are fed to the counting input of counter 2, to which counter 3 is connected in series with DR5TO. The number of bits of each counter. In the initial state, all bits, counter 2 are in state 1, and all bits, counter 3 are in state O. When the first impulse comes from generator 1, counter 2 is set to state O and for the first time counter 3 is recorded 1. Counter 2 in position 1 is set by the controller. impulse. coming from the analysis unit 6.
