dinenees with inputs BT ipoi o element AND-NOT 12, the output of which (: is connected to the input of the first driver 13, the output of the second driver is connected to the second input of the trigger 14, the input of the second driver 20 is connected to the second input terminal 17, the second output of the trigger 1D is connected to the first output of the second counter 6 is connected to the input of the third decoder 9, the second output is led 15, the second output of the first counter 3 is connected to the second input of the second counter 6, the first inputs of counters 3, 6 are connected to third input adhesive mm 18, the first output of the first counter 3 is connected to the second input of the distributor 11, and the output of the first element NAND 2 is connected to the second input of the first counter 3.

The device works as follows.

After a start pulse is applied to terminal 18, the first and second counters -3.6, 6 have enclosed, the device is reset. At the first output of the decoder 9, the potential of logical O is formed. Counter 3, with the arrival of each pulse from the output of generator 1, pulses alternately connects all inputs of distributor 11, on which logical potentials 1 are set in the initial state. HE 12 generates a logic level O at the output of the latter. When passing from the generator 1 n pulses after connecting all the inputs of the distributor 11, the last output of counter 3 generates a pulse that translates the counter 6 into a single state, thereby forming the logical O level at the second output of the decoder 9. Counter 3 again alternately starts connecting the inputs of the distributor 11 to the corresponding inputs of the NAND element 12. If there is an electrical connection, for example, between the first contact of one { a terminal and the third contact of another potential of the logic level O from the second output of the decoder 9 through the object 10.control enters the third dispenser of the distributor 11. When the counter 3 contacts the distributor 11, the third input will form

on the first of the inputs of the I-NK 1 element, the logical level O, which will cause a logical voltage drop from low to high at the output of the AND-HE element 12, the Shaper 13 forms a high-frequency pulse transferring the inverse output of the trigger 14 into the logical voltage difference logical O, which blocks the flow of pulses from generator 1 to counter 3 and the direct output of trigger 14 to logical level 1, which allows the indicators to light up. In this case, the indicator 1 lights up the number 1, and on the indicator 5 - the number 3, indicating the presence of an electrical connection between the first contact of one connector and the third contact of the other.

Device operation is suspended. Then, by applying a voltage drop to terminal 17, shaper 20 generates a high frequency pulse, which at R input triggers trigger 14 to its initial state, counter 3 begins to receive a frequency from oscillator 1, inter-coupling search resumes, and indicators 5 and 8 stop burning. If thereafter on the indicator 5 another digit lights up - this indicates the presence of an interconnecting connection on the second connector. A fault pulse supplied to terminal 17 permits the counter 3 to cycle through the inputs of the distributor 11. After all the inputs of the distributor 11 are connected and with the arrival of the i-th pulse from the generator, 1 last counter output forms the second pulse, which transfers the counter 6 to the second state thus forming the logical O level at the third output of the decoder 9. The device ends after interrogating all the contacts of the tested connectors, after which the last output of the counter 6 generates a pulse that lights the LED 15, informing operator checking all contacts of the tested connectors.

Having connected the object 10 of the control with the ground bus, the operator observes on the indicators 8 and 5 figures corresponding to the contacts of the tested connectors interconnected or with the body of the object 10 of the control.

To check the connection of the installation elements to the contacts of the object's 10 object control, terminal 16 is driven into contact with the outputs of the installation elements, and after the start pulse is applied to terminal 18, indicators 5 and 8 are fixed. The indicator 8 in this case shows the figure O, the indicator 5 is the number of the connector contact associated with the contact of the installation element being investigated. As each waste pulse is applied to terminal 17, indicator 5 shows the connector pins associated with the mounting element. Illumination of the light diode 15 informs the operator about the verification of all existing connections between the output of the adjusting element and the contacts

connector object 10 control.
