Sondes- For Non-Metallic Utilities - SPX Radiodetection Schonstedt u-LOCATE User Manual

Switch the Transmitter on then open and
close the Clamp. If the jaws are closing
correctly there will be a change in tone
as the jaws are closed.
An earth connection from the Transmitter
is not necessary but optimal signal
transfer is only generally achieved if the
target line is grounded at both ends. This
is usually the case with power cables.
Use the u-LOCATE LOCATOR to
scan the area for the target pipes or
cables (see 'Locating with u-LOCATE
LOCATOR').

Sondes- for non-metallic utilities

Sonde Signal Transmitter –The Sonde is a small self-
contained watertight signal transmitter which can be located
by the u-LOCATE+. Unscrew the Sonde housing and insert
batteries in the orientation shown by the diagram in the
battery compartment. To check for correct operation, place
the Sonde on the ground, set the u-LOCATE+ to Sonde Mode and, whilst holding it in
line with the Sonde, check that the signal is being received. Insert the Sonde into the
duct or drain and adjust the u-LOCATE+ sensitivity to receive the signal.
Smaller ghost signals appear before and behind the main signal position. Locate

Rotating the u-LOCATE+ about its axis to obtain the largest signal puts the
u-LOCATE+ in line with the Sonde and is a good way of identifying the direction
of the duct or pipe. Estimating Sonde depth using the u-LOCATE+ Do not use the
U-LOCATE+ depth estimation to decide if mechanical digging is appropriate.
Searching for a Sonde
Once in the surroundings of a sonde,

you are positioned along the axis of the
sonde(thedirectionofthepipe)oroff
to either side. In the sonde mode, the
directional indication is not functional;
the signal strength is the only indication
available.
Rotate the receiver back and forth and
move in the direction that produces the
maximum (peak) signal strength. As
the receiver gets closer to the sonde,
