How to use
Insert the appropriate connector (RJ11/RJ12 or RJ45) of the cable under test into the tester's main port and connect the remote terminator to the far end if the cable is installed. Power the unit using the installed batteries and observe the visual indicators while activating the test function. Read the pair status indicators to determine continuity, shorts or miswiring. For installed runs, use the supplied remote unit to isolate and verify each cable end. After testing, remove the cable and switch the tester off to preserve battery life.
Usage recommendations
Use fresh batteries and check indicator clarity before critical tests. When diagnosing faults, test both ends of the cable with the remote terminator to localize faults accurately. Avoid using the tester on live power circuits; ensure network devices are powered down or disconnected from energized lines where applicable. Store the tester in a protective pouch to maintain connector integrity and prolong service life.
