ST880 Cable Fault Locator is a portable open-air cable test instrument working on TDR and bridge methods, adopting advanced micro-electronics technology. It is designed to locate accurate fault points in such cables as telecommunication plastic cable or user’s lead covered wire, while the faults include break, mix, earthing, defective insulation, or poor connecting. It is an ideal function-stable instrument for the open-air operator to improve work efficiency; in addition, it can also be used for circuitry project checking electric property testing of the cable.
