operation screen.

Locating pipes and cables

For more detailed descriptions of using the
locator and transmitter, and for detailed
locate techniques, refer to the Operation
Manual.

The RD8100 locator is designed to operate
with the ‘blade’ of the locator perpendicular
to the path of the cable or pipe being
located.

Running a Self-Test

We recommend that a Self-Test is run at least weekly, or before each use. As the Self-
Test tests the integrity of the locate circuity, it is important that it is carried out away from
larger metallic object such as vehicles, or strong electrical signals. To run a Self-Test:
1. Press the

key to enter the menu.

2. Scroll to the INFO menu using the

arrows.

3. Press the

key to enter the INFO menu.

4. Select TEST using the

arrows.

5. Press the

key to select YES.

6. Press the

key to begin the Self-Test.

7. Once the Self-Test is completed, the result (PASS or FAIL) will be displayed.
8. Restart the locator using the

key

The transmitter can be used to recommend a general-purpose locate frequency for the
intended locate task by measuring the impedance of the target cable or pipe. To run

, connect the transmitter to the target utility, then:

1. Press the

2. Scroll to the OPT F menu using the

arrows.

3. Press the

4. Press the

key to start the test. The transmitter will automatically select a general

purpose frequency for use on the connected utility.

Locating with Active Frequencies

Active frequencies are applied to the target pipe or cable using the transmitter, and
provide the most effective way of tracing buried pipes or cables.
Generally speaking, it is better to use a low frequency on larger, low impedance utilities,
and move to a higher frequency on smaller, high impedance utilities.
The lowest power setting required to trace the target utility should always be used to
minimize the risk of false trails.
The transmitter can apply a signal using three different methods:

Direct connection

In direct connection, you connect the transmitter directly to the pipe or cable you wish to
survey using the red Direct Connect lead supplied. The black lead is generally connected
to earth using the supplied ground stake.
The transmitter will then apply a discrete signal to the line, which you can trace using the
locator. This method provides the best signal on an individual line and enables the use of
lower frequencies, which can be traced for longer distances.

WARNING! Direct connection to live conductors is POTENTIALLY LETHAL. Direct

connections to live conductors should be attempted by fully qualified personnel only
using the relevant products that allow connections to energized lines.

Induction

The transmitter is placed on the ground over or near the survey area. You select the
appropriate frequency. The transmitter will then induce the signal indiscriminately to
any nearby metallic conductor. In induction mode, using higher frequencies is generally
recommended as they are induced more easily onto nearby conductors.

Transmitter Clamp

An optional signal clamp can be placed around an insulated live wire or pipe up to
8.5" / 215mm in diameter to transfer the transmitter signal to the utility. This method of
applying the transmitter signal is particularly useful on insulated live wires and removes
the need to disconnect the supply to the cable.

WARNING! Do not clamp around uninsulated live conductors.

WARNING! Before applying or removing the clamp around a power cable ensure

that the clamp is connected to the transmitter at all times.
