Cable/Harness Tester
4-Wire Precision Cable/Harness Tester

Microtest 8761 cable/harness and connector testers can provide three different pins, such as 64, 128 and 256. The test profiles can be up to 500 sets or more. The on-state impedance accuracy is 10 times the 8750, avoiding the resistance issues caused from adapting the fixture wires, making the on-state measurement more accurate. To achieve the resolution of the on-state resistance of 1mΩ, the multiple filter line at the power supply is used, which reduces the generation of ripples 10 fold and also reduces thermal consumption and external power interference, giving the tester more measuring stability.
