How to use

Connect the tester main unit to one end of the cable and attach the remote adapter to the opposite end. Switch the tester on and observe the nine LEDs to verify continuity and correct pair assignment; the LEDs show each conductor and the shield. Interpret non-sequential or unlit LEDs as open, shorted or miswired conductors. Replace the 9V battery when LED brightness is reduced. Use the remote adapter to test permanently installed cabling runs.

Recommendations

For reliable diagnostics, test cables before installation and after termination. Replace the 9V battery regularly and store the remote adapter with the main unit to avoid loss. Do not expose the tester to moisture or extreme temperatures.
