How to use
Connect the tester leads or modular connectors to the two ends of the cable under test, ensuring a secure connection to both conductor pairs or shielding where applicable. Power on the unit and select the appropriate test mode if required; observe the visual indicators to determine continuity, short circuits, or incorrect pair wiring. For remote segment testing, attach the remote module to the far end of the cable and run the test from the main unit. Interpret the indicator pattern according to the supplied quick reference to identify the fault location and type.
Usage recommendations
Use the tester in dry, non-corrosive environments and replace batteries before extended measurement sessions. Verify connections at both ends before testing and avoid exposing the instrument to excessive mechanical shock or moisture. For ambiguous readings, recheck connections and repeat the test; consult cable installation standards for correct pair assignments when resolving miswiring.
