Fault Identification

Check Methods

Visual Check Carefully check the terminal connections of the plugs at both ends of the wire using a magnifying glass, to see if any exposed wires contacted with the adjacent pins which could cause a unexpected short circuit, as you can see in the following figures, click for larger pictures. These 4 wires should be insulated to each other or will result in a failure during the communication. This type of short circuit will only affect the communication but it will not cause a short circuit of power supply.

Instrument Test Test the pins adjacent to each other to see if any short circuit occurs by using a multimeter, if so, it's probably caused by the problems described above. Please make sure that the pens of the multimeter be connected to the metal pins firmly when testing.


If the above issue occurs, you could try to cut the exposed wires carefully using a knife. In order to being operated easily, the metal pins can be pulled out from the white plastic shell by unlocking the buckle with tweezers before operating. All the pins should be plugged back into their original positions in the correct order after finished. A properly fixed wire can be used normally without replacement.


Please contact our dealers for replacement if this issue can't be resolved.
