Signal induction

In the signal induction mode, the transmitter imposes a signal
onto the pipe or cable to be traced. It does so by energizing an
inductive antenna built into the case. The transmitter is placed
on the ground in a direction perpendicular to the pipe or cable
being traced. The inductive antenna then induces a current
onto the pipe or cable. In this mode, it is not necessary to
provide a return path for the induced current to the transmitter.
The induced current will travel on the pipe or cable for a
certain distance, making it possible to trace it.

Sonde (u-LOCATE+ only)

In sonde mode, the transmitter is not used at all. This mode is used
to trace non-metallic pipes, or metallic pipes where other modes
areinapplicableorinefficient.Asmallbeacontransmitter,orsonde,
is pushed through the pipe, and the receiver searches for the signal
emitted by the sonde.
Since the signal being traced by the receiver is produced by
the sonde and not travelling along the pipes, there are some
differencesinthewaythereceiverisused.Duetothenatureand
strength of the sonde signal, it is necessary to have some idea of
where the sonde is (in order to narrow the search area to a radius
of several feet centered on the sonde).

Operating recommendations

When using u-LOCATE, follow these tips and recommendations to improve and
facilitate your locating experience:

u-LOCATE and transmitter functional test

Schonstedt recommends that you perform a daily functional test on your
u-LOCATE /u-LOCATE+ Locator ("Locator") and Transmitter before use.
• Place the Transmitter on the ground, switch on and check for an audible sound.
Ifnosoundisheardorthelowbatterywarninglightisflashing,replacethe
batteries before use.
• Switch on the Locator by squeezing the trigger, checking for an initial 'chirp.'
A low tone indicates low batteries. If no sound is heard, replace the batteries
before use.
• Set the Locator to ACTIVE mode at maximum sensitivity, hold at waist height
pointing toward the Transmitter and check that the Locator can detect the
Transmitter up to 50 Feet (15m) away with a clearly audible sound.
