Using Accessories - Radiodetection RD8000 Bedienungsanleitung

Active Frequencies
Active frequencies are applied direct to the pipe or cable using the transmitter. 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. 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.
Connecting the transmitter to a pipe or line requires the use of a direct connection lead
and a ground stake to complete the circuit.
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.
Clamp
The optional signal clamp can be used to apply the transmitter signal to an insulated live
wire or pipe up to 8.5"/215mm in diameter.
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.
Refer to the Signal Clamps paragraph in the Using Accessories section.
Locating RF Markers
The RD8000 locator enables users to locate most common RF utility markers. These are
also referred to as Electronic Marker System (EMS) and Omni markers.
To enable marker locate mode lower the marker loop antenna. To disable the marker
locate mode fold the loop antenna up.

Marker types
The RD8000 can detect 9 different RF Markers, as shown in the table below.
UTI LI TY C OLO R
French Power Natural
General / Non-drinkable water Purple
Cable TV Black/Orange
Gas Yellow
Telephone/Telecoms Orange
Sanitary Green
German Power Blue/Red
Water Blue
Electrical Power* Red
*Use of the red Electrical Power (PWR) marker locate mode is subject to radio licensing restrictions
for Short Range Devices in the EU and possibly other countries. It is the responsibility of the user
to ensure that the red Power (PWR) marker locate mode is only enabled in countries where radio
licensing restrictions do not apply at the operating frequency of 169kHz.
If required and permitted use RD Manager to enable this frequency.

Using accessories

The locator and transmitter are compatible with a wide range of accessories. For detailed
information on using any of the accessories below please refer to the RD8000 locator
operation manual.
Signal clamps
When it is not possible to connect directly onto a pipe or cable, or induction mode is
unsuitable, a transmitter signal clamp may be used. The clamp is plugged into the output
of the transmitter and provides a means of applying a locate signal to an insulated live
wire. This is particularly useful with live insulated cables as it removes the need to disable
the power and break the line.
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.
To locate or identify individual lines a locator signal clamp can be connected to the
accessory socket of the locator and can be clamped around individual pipes or cables.
