How to use your locator and transmitter

Scanning an area before digging

An initial sweep using Passive Mode is recommended, followed by detailed scans
using the other modes. Use the Active mode for Depth estimation once a pipe or
cable has been detected. Turn the sensitivity control to maximum before starting. If
the signal bar graph does not move from maximum, reduce the sensitivity control so
that the bar graph is below half-way before starting. Sweep the area to be excavated
with a steady and deliberate motion. Begin by walking the perimeter of the proposed
excavation site. Then walk the length of the of the excavation site, moving across the
width in parallel sweeps around 18" (0.5 m) apart. If using a Transmitter in induction
mode, position the Transmitter as shown so that the chevrons on the u-LOCATE
are in line with the chevrons of the Transmitter. Then sweep across the width of the
excavationsite,movingupthelength.Ifacableorpipeislocated,firstestablishthe
direction of the cable or pipe, then trace it across the area to be excavated, marking
if required. Then resume sweeping over the excavation site.

Direct connection

WARNING: Connection to a power cable sheath should only be undertaken
by qualified personnel.

that it can be traced from above ground.
Connections can be made to any metallic
part of the pipe or cable such as valves,
meters, junction boxes, street lights,
pipeline markers or other access points.
WiththeTransmitterswitchedoff,
plug the Direct Connect lead into the
accessory socket. Attach the red lead to
the pipe or cable (if necessary, clean the connection point to ensure a good electrical
contact). If the jaws of the clip do not open far enough, and if the connection point is a
suitable material, use the supplied magnet.
Connect the black lead to the earth stake which should be secured in the ground 3 –
4 m away from, and at right angles to the target line. Alternatively the black lead may
be clipped to a valve box, manhole cover or another earthed point. Use the earth
spool lead to extend the earth connection if necessary.
Switch the Transmitter on. A good connection is indicated by a drop in loudspeaker
