Note generally these services should be detectable using the radio or generator modes. In power mode the locator detects power signals. These power signals are present on all current carrying electricity cables although not all are detectable. These power signals may also flow along other buried con...
Page 8
In radio mode, the locator detects signals from radio transmitters. These signals flow through the ground and will tend to follow the line of least resistance such as a buried metallic service. When this happens the service can often be detected by using the locator in radio mode. Limitations of rad...

There are three stages to the locating process; searching, pinpointing and tracing 1. Turn the function switch to the appropriate mode 2. Hold in the on/off trigger. The locator should emit the audible battery test tone and the digital display should come on. Check the battery level indicator to con...
Page 13
Having found the presence of a signal the next stop is to pinpoint the source. The closer the locator is to the signal source the stronger the response. To pinpoint a signal 1. Keeping the locator vertical, walk through the area of the signal response. If the visual response goes off the scale then ...
Page 14
Using the locator: tracing having pinpointed a service it should now be possible to trace it’s route. 1. Carefully follow the direction of the signal holding the locator at right angles to the line of the signal. It is necessary to constantly ‘slice’ the locator from side to side in order to be sure...

Signal generator: induction this is the standard method for inducing signals onto buried metallic services. It produces a strong signal directly below the signal generator but the signal strength drops off quite quickly either side of the signal generator. 1. Check that there are no accessories plug...
Page 24
Signal generator: searching for an induced signal the search pattern used to find the signal generator signal when applied by induction is slightly different to the search pattern used on the power or radio modes or with the signal generator on the direct connection mode. 1. Move at least 10 metres ...
Page 25
Signal generator: searching for an induced signal 4. Walk in a straight line across the end line of the signal generator. When a signal is detected ‘pinpoint’ that signal as shown in the ‘using the locator’ section. If no signal is found move the signal generator 5 metres and try again. Continue thi...

Signal generator: induction multiple services it is important to check for the presence of adjacent services running close, or parallel, to the conductor you have located. 1. Check that there are no accessories plugged into the connection socket. 2. Turn the signal generator on and check that the ba...
Page 27
Signal generator: using an inductive sweep if a large area needs to be searched for buried services then an ‘inductive sweep’ could be used. It is an ideal method for detecting the position of buried services as they cross the boundary of a large site. An inductive sweep requires two people; one to ...

Non-metallic pipe tracing: plastic pipe tracer line tracing the plastic pipe tracers can be used in services up to 2metres deep and do not work through metal pipes or ducts. The plastic pipe tracer needs to be inserted into the pipe before a signal from the signal generator is applied to the length ...
Page 32
Note it is important that a change of tone is heard when making the connections to ensure that there is a detectable signal present on the tracer. Note end tracing is the ideal method to use to determine where the end of the pipe is but does not give the route of the pipe. Non-metallic pipe tracing:...
Page 33
Depth measurement the c.Scope cable avoidance tool xd can be used in conjunction with the signal generator or sonde to indicate the depth of a buried service. Depth cannot be measured on the power or radio modes. 1. The signal generator must be set to “continuous” signal output, not pulsed output. 2...
Page 34
4. Press and hold down the depth button. The depth will be shown on the display, measured in metres. 5. The depth should be verified by lifting up the locator whilst keeping the depth button depressed. The depth indication should increase by the same amount. Limitations of depth measurement - there ...
