6 Using SiS Mode Accessories
9. Note the signal reading of each cable. The one with the largest reading is likely to be the target cable.
10. If necessary, adjust the sensitivity of the vLoc3-5000 so that the signal is within the operating section of the bar graph.
WARNING
The remote stethoscope antenna is a useful tool to help trace cables. However, it should not be used
as positive identification before an unused cable is cut. Always follow company procedures when
cutting disused or isolated cables.
TIP
The remote stethoscope antenna can be used to help trace disused and isolated cables. This process
can be further enhanced if the cable is isolated and is of a twisted cable construction.
Method:
1. Connect the transmitter to two of the cores of the cable. At the far end, short together these two conductors making a loop.
2. Set the transmitter to a low frequency such as 640Hz and set the output to maximum.
3. At the point of interest, if possible part the suspected cable from the bunch then run the remote stethoscope antenna
along the suspected target cable keeping the flat portions of the antenna in line with the cable. If the correct cable is being
assessed the signal will increase and decrease in sympathy with the twist of the two conductors within the cable.
4. If the signal is a steady level and does not rise and fall, this is probably not the target cable.
WARNING
The remote stethoscope antenna is a useful tool to help trace cables. However, it should not be used
as positive identification before an unused cable is cut. Always follow company procedures when
cutting disused or isolated cables.
6.3 Using the SiS Mode with the Remote Antenna
The use of a Remote Antenna to help identify a cable can be further enhanced with the use of a Signal Select Signal.
