Description

one

This invention relates to devices for automatically controlling electrical circuit parameters, such as insulation resistance. The known devices of this assignment, which contain a pulse generator, two counters connected in series, two decoders, a control unit, the AND circuit, take considerable time to check and are intended to check a certain number of circuits.

In order to shorten the testing time by eliminating repeated pro- scans and to ensure that the device can be used to test products with different numbers of electrical circuits, the input of each decoder of the proposed device is connected to one of the devices. the poles of the control unit, as long as the Xth output of the first decoder is connected to the jt -th output of the second decoder. The moves of each second bit of the second counter are connected through the circuits AND, to

To the input of which the output of the first counter is connected, from the input of the same bits of the first counter. The output of each digit of the counters is connected to the input of the following bit via the switching contacts of the relay, the winding of each of which is connected to the switch of the switch.

Fig, I shows the block diagram of the described device; FIG. 2 is a limitation scheme. the number of tested circuits.

The device consists of a generator shlpulsov 1, schemes And, 2, counter 3, decoder 4, delay line 5, control unit b, counter 7, decoder 8.
