Reading the LED indicators
The pin indicator LEDs should flash in sequence from 1–8. If the LEDs do not flash, or flash out of sequence,
it can indicate a problem with the cable. The following table describes the meaning of the indicators.
Indication Meaning
All LEDs off, no beep Pin 1 is faulty or damaged. Pin 1 needs to be connected in order for
the cable tester to begin testing the other pins.
The number of LEDs that light up
depend on the number of pins in
the cable A 5-pin cable will illuminate LEDs 1 through 5. The other LEDs will
not light up.
LEDs light up in order There is good continuity on each pin.
One of the LEDs does not light up 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 LEDs for pin 3 will light.
LEDs flash out of sequence 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.
Continuity tester
1) Connect the two test cables provided to the banana jacks (7) of the continuity tester.
2) Hold the test probes to the two ends of the cable to be tested, no carrying any voltage.
3) When there is good connectivity and continuity, the beep will sound and the LED between the jacks will
light up.
Using test tones
The test tone (1 kHz sinus, +0/-10/-50 dB) from the tone generator is sent out from the jacks on the receiver.
This is a balanced signal and, the positive signal is on pins 2 and 4, and the negative signal is on pins 3. Pin
1 is grounded. If you are testing an unbalanced device, the output level is halved.
1) Connect the cable to your audio device and the receiver.
2) To send out the test tone, set the selector switch (5) on the receiver to TONE TEST. The power indicator
(4) lights up.
3) Select the amplitude of the test tone with the volume selector (6). If you are testing line-level devices or
speakers, use a level of +0/-10 dB. If you are testing a mixer’s microphone input and thereby its mic
preamps, you will want to use a level of -50 dB. Otherwise you may overdrive the mic preamps.
4) To switch off, set switch (5) to OFF.
