WARNING: Exposure to voltage can
damage the tester. Immediately disconnect the
cable under test if the Voltage warning appears
on the display. Make sure the cable is not
connected to any device that can supply
voltage before retesting.
Do not connect two different cables into the
Voice (RJ11/RJ12) and Data (RJ45) test ports
at the same time. The cables will interact
with each other and alter test results.

Pass appears on the display indicating a properly wired cable. The pin numbers on the
top row and bottom row are the same indicating proper continuity.
A cross wired cable reverses the connection at one end of the cable. Pins 1, 6 cross over to
pins 6, 1, pins 2, 5 cross over to pins 5, 2, and pins 3, 4 cross over to pins 4, 3. Cross wired cables
are often used between the wall port and phone.
Pass and X-over appear on the display indicating a properly wired cross wired cable. The pin numbers
on the bottom row indicate the corresponding reversal to the pin members on the top row.
The pair on pins 3 and 4 is shorted and the pair on pins 1 and 6 is open.
Fail, Short and Open appear on the display indicating a defective cable. The pins with wiring errors will
flash. The dash lines below pins 3 and 4 indicate a shorted pair. The blank space under pins 1 and 6
indicate an open pair.
