Kopul CBT-MF Multi-Function Cable Tester with Dual Chassis - Manual (Page 8)

Use the table on page 9 to verify proper pin connections.
None of the LEDs light up and there is
no beep
The number of LEDs that light up depend
on the number of pins in the cable
LEDs light up in order
One of the LEDs does not light up
LEDs flash out of sequence
PIN 1 is faulty or damaged. PIN 1 needs to be connected in
order for the CBT-MF to begin testing the other pins.
A 5-pin cable will illuminate LEDs 1 through 5. The other LEDs
will not light up.
There is good continuity on each pin.
There is a faulty connection, grounding problem (short circuit), or
possibly a broken or damaged wire on that pin.
Example: If PIN 2 of a 3-pin XLR cable is faulty, you will hear the
beep and see LEDs for PIN 1, then the LEDs for PIN 2 will not
light up, and then the LED for PIN 3 will light.
This indicates that the cable has not been wired properly.
Example: If an XLR cable has been wired 1-3-2 instead of 1-2-
3, the beep will sound along with LED 1 confirming PIN 1’s
connection, and then you will see LED 3 followed by LED 2.
