Time Domain Reflectometry (TDR):
Can detect open circuits, mixed lines, and severe insulation faults, with fast and accurate automatic testing.
♦ Gain Compensation:
Digitally compensates gain based on cable attenuation characteristics, making waveform amplitudes at different distances essentially the same, which aids analysis and extends effective test distance.
Waveform storage and computer communication functions.
♦ Bridge Test Method:
Suitable for locating insulation fault distances; fast test speed; strong anti-interference capability; precise distance measurement results.
♦ Voltage, resistance, and insulation resistance measurement functions.
