Signal Current Measurement
(
MXL2 Locator only
)
Signal Current Measurement can also help to identify the layout of pipe and cable networks
as the main line after a ‘T’ will have most of the Signal Current remaining on it whereas the
shorter connection will have correspondingly less.
The Signal Current reading should also reduce at a uniform rate as the distance from the
Generator/ Transmitter increases. A sudden drop in Signal Current, in a short distance,
indicates a change to that service such as an unknown connection, an insulated joint or
a break in the pipe or cable.
