    CableEye M2U Basic Cable Tester

    The M2U Basic is the smallest system for the cost-sensitive application of cables with up to 128 pins. This is the only model that cannot be upgraded at a later point in time in case more test points are needed.

    CableEye M2U Basic Cable Tester

    CableEye M2U Full Cable Tester

    The M2U Full offers the standard 128 test points plus an additional 24-pin bank. This model can be expanded in 128-pin steps.

    CableEye M3U Cable Tester

    The M3U is the first of the CableEye family to offer the capability to measure resistance and diodes. Errors and embedded components are easy to check.

    CableEye HVX Cable Tester

    The HVX ist he high-voltage tester in the CableEye series. The low-voltage part works just like the M3U. The high-voltage part allows users to test cables for leakage at up to 1500VDC/1000VAC. Isolation resistance is measureable at up to 1GΩ.
