6     Using SiS Mode Accessories

It is a good idea to synchronize the receiver with the transmitter at the beginning of a survey, pinpoint the line very close to the 
transmitter – be sure that it is the correct line. Then, standing facing away from where the transmitter is attached, undertake the 
reset procedure as outlined above in the section 3.12 “Synchronizing”.

Used in conjunction with the vLoc3-5000 receiver, the Signal Select feature becomes a powerful tool in aiding accurate cable 
identification. At the receiver, a positive (+) icon appears on the operational interface if the operator correctly identifies and 
traces the line.
A negative (-) icon appears on the operational interface if the operator finds a parallel line or a return current instead of the 
desired line. Tracing along a line will provide a constant indication of the same polarity.

NOTE

It is also possible to apply an 8.44kHz SIS signal using the 4 or 5” (100mm or 125mm) standard clamp. 

When using clamps it is recommended that a SIS reset is performed at a point that is known to be the 

target cable.

6.2  Using the vLoc3-5000 SiS Remote Antenna

The remote stethoscope antenna can be used to help trace a particular cable on a cable tray or where cables are bunched 
together.

Signal Select Antenna Mode

Plugging the Signal Select Remote Antenna supplied by Vivax-Metrotech into the output socket will place 
the transmitter in “Signal Select Antenna” mode. An icon confirming this is displayed on the display. The icon 
flashes when the transmitter is transmitting.

Using the Remote Antenna

Methods:

1.  Connect a signal to the cable to be identified. The remote stethoscope functions has an operational frequency range of 

512Hz up to 200 kHz, but low frequencies should be a preference in this application as they are less likely to leak or bleed 
over to other cables.

2.  When cables are earth bonded together and the cross bonds cannot be removed, the best method of signal application is 

to use the signal clamp.
