When linked to PC, CableEye Model M3 finds cable defects; flags defect in color on wiring diagram; stores wiring notes and labels; and prints schematics. Tester measures 0.5 ohms to 10 megohms on 152 test points, which can be cascaded to 1,024 test points; it also tests diodes and resistors, and supports adjustable resistance thresholds. Multiple networked systems can share common database, test programs, and system settings.
