This tester can be used to simply verify the integrity and efficiency of the cable line.
You will need:
5-pin XLR papa;
Two 270-omnyh resistance
The scheme must be connected to these connector pins and put in his body so that the outside remained only LED.
Plug the tester into the socket, which must be verified.
Put on the console all the channels at 0 percent. Diode turns one color.
Set all channels are filled. Diode should light up another
If the diode is off in one of the two cases, this means that there was a short circuit between one of the lines and the first contact.
Nothing special, but it is often useful!
