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 RD7100 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.
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 and locator signal clamps
Locator clamps can be used to identify a target cable or pipe amongst a number of
different cables by checking for the strongest locate signal. When cables are bunched or
tightly packed, a stethoscope antenna can be used in place of a clamp.
To use a stethoscope or locator signal clamp, connect it to the locator’s accessory socket.
The locator will automatically detect the device and filter out location modes that are
irrelevant.
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. Some models of the RD7100 can detect
a range of sonde frequencies, including those transmitted by flexiprobe
™
P540c pushrod
systems and P550c 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 Tx-5 or Tx-10 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.
No additional settings are required for the Tx-1 transmitter.
