CableEye checks cables and wire harnesses for opens, shorts, and miswires; measures diode forward voltage; checks resistance values from 0.3 ohms to 10 megaohms; and tests conduction and isolation resistance against specified thresholds. Its Light Director accessory delivers computer-assisted technique for assembling circular connectors. Light fibers, driven by super-bright LED lamps, individually illuminate target cavities, and synthetic speech can also read pin number.
