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.
