Abstract:
     The present digital type apparatus for checking up lines is a code checking apparatus used for communication cables and power control cables. The said invention changes the conventional method of checking up the lines pair-by-pair commonly used in this particular technical field, solving thus the previously unresolved difficult problem of fast direct reading, and giving digital direct display of cable numerations. In its operation, said invention utilizes an electronic scanning encoded output, by using the coding to be measured to control a counter and a register, it provides the decoding and display of single encoded lines, realizing thus the direct digital display of cable numerations, and achieving the goal of high capacity and high accuracy testing.
