Depth, current and compass readouts
WARNING: Never use the depth measurement readout as a guide for mechanical or
other digging activity. Always follow safe digging guidelines.
The RD5100H
2
O+ locator can measure and display the utility depth, locate signal
current and the relative orientation of the cable or pipe to the locator. This helps you to
make sure that you are following the right cable or pipe, especially when other utilities
are present.
The RD5100H
2
O+ locator features TruDepth
™
, a feature that helps you to ensure
the accuracy of your locates or Survey Measurements. The depth and current are
automatically removed from the display when the locator is at an angle of more than
7.5° from the path of the cable or pipe being located, or when the locator determines
that signal conditions are too poor for reliable measurements.
Current Direction (CD)
The RD5100H
2
O+Tx transmitter can apply a unique CD signal onto a pipe or cable. This
signal can be used to identify an individual pipe or cable amongst a number of parallel
utilities, ensuring operators follow the right line. A CD signal clamp or direct connection
leads can be used to apply the unique signal to the pipe or cable and a CD locator
clamp or CD stethoscope can be used to identify individual pipes or cables.
Using accessories
The transmitter is compatible with a range of accessories. For detailed information on
using any of the accessories below please refer to the RD5100H
2
O+ locator operation
manual.
Transmitter 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.
Sondes, Flexrods and FlexiTrace
Sondes are battery powered transmitters that are useful for tracing non-metallic pipes.
They can be fixed to Flexrods to allow them to be pushed through pipes or conduits,
and some are suitable for blowing through ductwork. The RD5100H
2
O+ can detect
a range of sonde frequencies, including those transmitted by flexiprobe
™
pushrod
systems and 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.
The FlexiTrace has a maximum power rating of 1W. When using the FlexiTrace with a
Radiodetection RD5100H
2
O+Tx transmitter, the output limit must be set to 1W in the
MAX P menu and the output voltage limit set to LOW in the MAX V menu.
Plug / Live cable connector
The plug connector is connected to the output of the transmitter and is used to put
a signal onto a line and trace it from a domestic mains plug to the service cable in the
street.
The live cable connector can be used to apply a signal to a live cable. Only suitably
qualified personnel should use this equipment.
