A locate where a transmitter is used to apply a signal to a buried pipe
or cable, the position of which is then located by a receiver tuned to
the same frequency.
A signal applied by the locator transmitter to a buried line. Typical this
is a very precise frequency.
The reduction of an electromagnetic signal from a pipe or cable.
An accessory used to apply the transmitter signal to an insulated
line, removing the need to connect the transmitter signal directly to a
conductor or cable sheath.
The act of signals transferring to lines to which they were not originally
applied. Coupling can be “direct” where the target line has an electrical
connection to another line, or “induced” where the signal radiates from
the target line to another line or lines.
The information visually available on the dot matrix display.
A generic term for any buried pipe or cable.
A minimum response to a buried line
A locate where the receiver searches for a wide range of signals that
radiate from buried pipes or cables. These signals come from a variety
of sources in the environment and couple to the buried (& overhead)
lines. Typical examples 50/60Hz and LF/VLF radio.
