Operating the cable tester
Testing cables:
1. Plug the connectors of the cable into the corresponding jacks on either side or the top of the
cable tester.
2. Switch the selection knob to “1.”
3. Turn the knob one click at a time to test each pin on the cable (see table on pages 5-6).
Reading the LED indicators
•
Yellow and green LEDs light up: There is good continuity on that pin.
•
Yellow, green or both LEDs do not light up: There is a faulty connection or possibly a broken
or damaged wire.
•
Ground LED lights up: There is a short circuit in the cable caused by a connection between
the pin and the shell.
Use the tables on pages 5-6 to verify proper pin connections
