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 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 can detect 9 different RF Markers, as shown in the table below.
UTI LITY COLOR D I S PLAY FR E QU E N CY
AB B R EVIATI ON
French Power Natural PFR 40.0kHz
General / Non-drinkable water Purple PUR 66.35kHz
Cable TV Black/Orange CTV 77.0kHz
Gas Yellow GAS 83.0kHz
Telephone/Telecoms Orange TEL 101.4kHz
Sanitary Green SAN 121.6kHz
German Power Blue/Red PDE 134.0kHz
Water Blue H20 145.7kHz
Electrical Power* Red PWR 169.8kHz
*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 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.
Stethoscopes
At times, it may not be possible to use a clamp around a cable because of congestion
or inaccessibility. A stethoscope antenna should be used in place of a clamp to identify
cables.
Radiodetection supplies a range of stethoscopes to suit most applications.
To use a stethoscope, connect it to the locator’s accessory socket. The locator will
automatically detect the device and filter out location modes that are irrelevant.
Sondes and FlexiTrace
Sondes are battery powered transmitters that are useful for tracing non-metallic pipes.
The can detect a range of sonde frequencies, including those transmitted by
Flexisondes, GatorCam
™
4 or flexiprobe
™
pushrod systems and P350 flexitrax
™
crawlers.
For a detailed guide on locating sondes, please refer to the operation manual.
A FlexiTrace is a traceable fiberglass rod incorporating wire conductors with a sonde
at the end. It is connected to the output of the transmitter and is typically used in small
diameter, non-metallic pipes. The user has the option of locating the entire length of the
cable or choosing to locate only the tip of the cable.
