Description of the System
2.1
System Information
Locators are used to detect buried conductive utilities that emit an electromag-
netic signal. Such a signal is generated as an electrical current passes through
the utility.
Signal transmitters are used to apply a distinct signal to utilities with the fol-
lowing intention:
•
To improve the detection success.
•
To trace the route of a utility.
•
To make a depth or current measurement.
Accessories are used with the locator and transmitter to localise the position
of utilities, including some that are non-metallic.
The locators and transmitters described within this manual greatly facilitate the
search process and help to reduce the dangers and costs associated with utility
strikes. However, electromagnetic location depends on the utilities being con-
ductive (metallic) and emitting a signal as current passes through them.
☞
Keep in mind that a locator on its own cannot detect all utilities. Take
care when excavating. We recommend that you adopt a safe system
which includes the planning of the search process in advance, the use
of utility maps, the use of locators and transmitters, and the use of
safe digging practices.
