CableEye Models M3Z and M4 look identical on the outside. Internally, M4, shown below, uses a different circuit board that enables it to measure capacitance. The first photo shows catalog Item 824, the CableEye M4 system with the CB18A board set attached. Remove the interchangeable CB boards by pressing apart the latches near the front of the board. Choose from over 60 different CB boards to accommodate over 200 standard connector types, and use the CB8 board for prototyping and circular connectors accomodating unlimited connector types. Like the M3Z system, the M4 control module offers a small bench footprint and the ability to handle cables and harnesses of up to 64 conductors plus accessories such as a footswitch, probe, or minihooks. For larger cables or harnesses, attach an expansion module to M4, Item 825 (vertically stacked). USB interface standard.
Every tester ships with our comprehensive operating software and, for the M4, reports twist pairing and wire resistance results as shown below. A computer is required and not included.
