ST880 Cable Fault Locator is a portable instrument operating on TDR and bridge methods, utilizing advanced micro-electronics technology.

It is designed to locate faults include break, mix, earthing, defective insulation, or poor connections. The results are saved to a PC via USB connection or directly on a USB memory stick.

The unit’s rugged casing makes it an ideal instrument for the field testing. Improve work efficiency; in addition, it can also be used for circuitry project checking electric property testing of the cable.

• Combining both TDR and Bridge testing modes, which can be used for faults such as break, mix and defective insulation of a cable.
• Advanced 200 Hz frequency sampling for higher accuracy
• High accuracy at long In long distance test by using small wave to improve testing at long distances
• Transfer data via USB port, store test results on PC via Management Software USB stick
• Automatic measurement to find fault point
• Manual measurement is also available
• Easy to use Menu driven operation
• Includes functions of Tram Megger and Ohmmeter, which can test insulation, resistance and loop resistance
