Lie, whose invention is a link to the efficiency and accuracy of verification by taking into account the mutual relations between the channels.

FIG. Figure 1 shows the bianch diagram of a device for re-machining the proposed cih; soba; in fig. 2 - electric circuit of the eight-channel switchboard with the allocation of all channels into four groups.

The device (Fig, I) consists of the INR () of the channel switch I, the master oscillator 2 with a cell 3 delays, counter 4, two generators 5 and 6 of excitation, one | of their electrical pulses and two distribution switches 7 and 8, You.ho Generator 2 i is connected to controllers of a multichannel switch 1, counting 4, and through a cell, 3 delays with generators 5 and 6. they are connected to the signal inputs of each of the distributive KOMMyiaropDH 7 and 8. The control inputs of which are I-IKMI: yen with the output of counter 4, and the outputs. with the corresponding si1-nal inputs U 12 and 1.3 16 of the multichannel switch I, 71 l each ka) 1 a m in a mogogokan, 11, H1, l1 to () mmut; The torus (Fig. 2) has four 1 1 New; |) Ezisgore, four pairs; n Dop: nig.1, 1x peincTOpa and one nofiMa.ii. open) contact) after.

And, between the connection points of resistors 21 and 23 and 22 and 24, the normal connection is connected) () wired contacts of relay 25, the windings of which are connected to the control input of a multi-channel switch In addition, all channels are divided into groups of two channels each in such a way that their resistors 17 and 18, as well as 19 and 20 are connected to the same corresponding signal inputs of a multi-channel switch.

The device operates as follows. A multi-channel switch is included in the tested seismic recording equipment between seismic receivers, which can be placed on the profile (in working position), and the inputs of the preliminary amplifiers of the recording equipment. The device operates with repetitive cycles of excitation and transient process recording. 4aj cycle cycles are set by a manual peer that is part of the specified gene.
