GEAR TESTING WIRING Russian patent published in 1998 - IPC

FIELD: automatics, computer engineering. SUBSTANCE: gear has clock generator, counter, two decoders, indication unit with two groups of light-emitting diodes, indicators of shut-down and termination of operation, flip-flop, NOT-OR gate, former of pulses of start and continuation of operation, former of shut-down pulse, smoothing capacitor, two load resistors, n voltage followers with open collector, n OR-ELSE gate with open collector, transmitter, receiver, communication means, mode switch and prod. Gear is composed of two parts and that is why it enables n-core bundle already laid in closed duct to be tested. It can also test bundle with special wiring or identify numbers of wires in bundle. Complete picture of state of tested object is displayed on indication unit ( short-circuit, break, special connections ) which presents technical result of invention. EFFECT: expanded functional capabilities and increased authenticity of information obtained by gear. 1 cl, 5 dwg
