Cable Harness Tester
Cable/Harness Tester

The 8730FA/8730NA/8730N make a break through on the professional wire testing instrument technology. In order to promotethe fast and convenient testing work and more wire setting to the production line personnel, 8730 increases the number of the files setting storageup to 250 groups. It makes thecalling speed of setting information fantastic fast! To meet the test requirement of the high production and precise wire, MICROTESTpromotes the sensitivity of the inspection ability of the momentary broken circuit with leading technology. It makes the test speed faster and the conduct preciseness higher.

  • Test pin 128/256/512
  • Number of test file up to 250 sets
  • The measurement items: Open/Short, Conductance, Components ,AC Hipot, DC insulation/Hipot, Quick conductance, Intermittence O/S, and Quick Intermittence open circuit
  • Multiple DUT test - 6 (standard)
  • Support bar code scan and print function
  • External current expand box for wire buck measurement

To measure the wire, you must first form a loop and then measure.When both ends of the wire are plugged into a 8740NAC or a circuit is created by a fixture, press "learn" from the front panel.The Nets/Pin value will be automatically displayed on the upper right of the 8740NAC screen.The example at the top right of the figure is 26Pin/loops (Net), 56 Pin.
