Brief introduction:
ST880 Cable Fault Locator is the latest test instrument; its working principle is Time Domain Reflectometer (TDR), wavelet and Bridge Methods. It is a very convenient, intelligent and reliable instrument for precisely locating cable faults, like open circuit, short circuit, cross faults, poor insulation and balance test, etc. We can also transfer the fault data to PC via cable or Flash Disk.
Functions and features:
-The TDR method and Bridge Method for fault detecting, faults like open circuit, short circuit, poor insulation.
-Multimeter function: it can be used to detect isolation resistance and loop.
-Automatic Detection: advance and precise.
-Manual Detection: easy to detect, it matches with automatic detection to give the operation a very precise result.
-Waveform Storage: store 20 waveforms together with the fault time permanently.
-Wavelet detection: technology used for long distance fault detection, this can increase the detection range and accuracy.
-Data transfer: the operator can transfer the data to PC with a Flash Disk. The software installed in the PC can analyze the waveforms, establish database for the waveforms, and print if necessary.
-Friendly Human-Machine Interface (HMI), easy to use.
-Internal recharging Li-Ion battery, long life span and short charging time.
-Small in dimension, and light in weight, easy to carry bag.
