4-Wire Resistance Measurement | Continuity & HiPot Cable & Wire Harness Testers
-
An add-on option for the CableEye HVX high voltage cable tester series that permits expanded testing for contact and wire resistance as low as 1 mΩ. After checking for opens, shorts, miswires, and resistance limits, the 4-wire Kelvin measurement applies a user-selectable test current from 10 mA to 1 A to determine connection resistance within 1 mΩ. The resistance profile of a model cable may be stored and used as a basis of comparison during later testing to reveal cold solder joints, faulty crimps, recessed pins, pin contact contamination, improper wire gauge, and stress-extruded wire.This option may be purchased with any new HVX tester, or added as an upgrade to any of your existing HVX testers.
