Wire & Cable Testers
TDR-420 Time Domain Reflectometer/ Cable Fault Locator
Product features
- Possibility damage-free location of impedance changes of tested cables and wires such as:
- shorted conductor,
- open conductor / end of cable – useful during the inventory of warehouses and stores,
- splice,
- splitter,
- water ingress,
- wet splice,
- bridge tap
- or other changes.
- Single measurement mode ONCE,
- Continuously measurement mode CONT,
- Tone signal generator TONE,
- Two cursors to mark two places of damage along with an indication of the distance between them,
- Built-in HELP function for easier interpretation of the reflectogram,
- 11 available measuring ranges from 7 m to 6000 m,
