Locating pipes and cables with the
RD5000
Applying the signal using direct connection
In direct connection, you connect the transmitter output directly to the pipe or to the
conductor of the cable you wish to survey. The transmitter will then apply an active
frequency signal, which you can locate using the locator. This is the preferred method
for providing the strongest signal on a particular line and is particularly useful for long
distance tracing.
Connecting the transmitter to a pipe or cable in direct connect mode, requires the
use of a direct connection lead, which is connected to the accessory socket of
the transmitter. The red lead is connected to the pipe or cable and the black lead
connected to an earth stake to complete the electrical circuit.
WARNING! In Direct connect mode, output voltage can be up to 30V RMS
which is POTENTIALLY LETHAL in wet conditions.
WARNING! Direct connection to live wires is POTENTIALLY LETHAL.
Direct connections should be attempted by fully qualified personnel only!
Applying the signal using induction
When it is not possible to use the transmitter in direct connection mode, the
transmitter can be placed on the ground over or near the survey area with the arrow
on the transmitter in line with the target line. The transmitter will then induce the
signal indiscriminately to any nearby buried metallic conductors. When using the
transmitter in induction mode it should be noted that the signal from the transmitter
will transmit not only below the transmitter but above the transmitter and it is
recommended that the locator should not be used within a minimum of 15 meters
(50 feet) from the transmitter.
Applying the signal using a transmitter signal
clamp
When it is not possible to use either direct connection or induction methods, a
transmitter signal clamp, can be used to induce the signal onto the target line.
Connect the clamp to the accessory socket of the transmitter and fit the clamp
around the target line. The clamp is particularly useful with insulated live cables as
this removes the need to disable the power and break into the line.
