6 Using the vLoc-5000

As a result there can be multiple signals radiating from cables and pipes in the area making it difficult to
identify the target line. These return signals are typically traveling in the opposite direction than the applied
signal. The Signal Direction feature identifies which direction the signal is flowing and hence the target line.
To use the signal direction system:
Connect the transmitter to the target line using a direct connection only.
Turn the transmitter and receiver on and set both to:
o
SD-USA – if in North America or any territory where the power system is 60Hz.
o
SD-EUR – if in Europe or any territory where the power system is 50Hz.
The receiver may, or may not be flashing the “SD” icon "A flashing icon indicates that the unit needs to be
synchronized with the transmitter.” Even if the icon is not flashing it is always good practice to
synchronize the system at the beginning of a survey to ensure reliable results and to maximize the
distance to the next synchronization point.
To synchronize the receiver to 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 and press the “i” pushbutton. The unit will now display the information screen showing the
depth of line, signal current and a hand with the “SD” icon positioned over the return pushbutton.
Pressing the return pushbutton will synchronize the system and return the unit to the locate screen. The
Line Direction Indicator will now be pointing forward and the SD icon will not be flashing indicating the
receiver is locked onto the signal. The system is now synchronized.
Proceed to locate, trace, pinpoint as required ensuring at all times the line direction indicator is pointing
forward.
If at any time the line direction indicator is pointing backwards – you are not locating the correct line, you
are locating a line which is carrying the return signal.
