Signal Direction (SD)
(Available for vLoc3-Pro with SD and vLoc3-ML models only)
Signal Direction, SD Mode is used to verify if the line being located is the target to which the transmitter has
been connected.
When a transmitter is connected to a target line, the signal travels along it and finds the easiest way to travel
back, usually via the ground and ground stake. However, very often the signal will travel back along adjacent
cables or pipes as these can offer an easier route.
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.
