DEVICE WHICH TESTS ELECTRIC WIRING Russian patent published in 1998 - IPC

FIELD: automation and computer engineering. SUBSTANCE: device has clock oscillator, counter, two decoders, indication unit which has two groups of light-emitting diodes, indicators of stop state and finish of operations, NOR gate, generators of start pulse and pulse for continuation of operations, smoothing capacitor, load resistor, connection wire, n voltage repeaters and n NOT-XOR gates with open collector. Device consists of two parts. This results in possibility to check n-wire bundle which is mounted in channel without access. In addition bundle with special wiring can be tested including total access to tested object states using indication unit (short-circuit, break, special connections). EFFECT: increased functional capabilities, increased information capacity. 1 dwg
