3) Use
The following instructions must be followed to avoid electric shock, short
circuit, or explosion:
•This cable locator can be used in live parts, but measures must be taken
according to industrial safety codes to avoid electric shock and damage.
•To avoid electric shocks, you must pay special attention to the VDE and
safety regulations in force regarding excessive contact voltages, when
working with voltages that exceed 120V (60V) DC or 50V (25V) rms AC.
Values in parentheses are valid for limited scopes (such as medicine and
agriculture).
•Never try to put both battery poles in contact, for example by connecting a
cable. Never throw the battery into a fire, or it could cause an explosion.
•When replacing or changing the battery, be sure to use the correct polarity.
Batteries with reversed polarity may destroy the instrument. They could also
explode or catch fire.
Attention!
•Measurements near electrical installations that may pose a hazard should
only be carried out under the supervision of the responsible electrician.
•When the product is used to test a live line, make sure that the test
connectors are disconnected from the object under test before connecting
or disconnecting the test lead from the emitter, and remember that people
around must be well protected.
•Never try to remove the battery posts! The battery contains very strong
chemical agents. Danger of corrosion! If the contents of the battery come
into contact with the eyes, rinse immediately with plenty of water and
consult a doctor.
•Since the connection of the emitter with the mains can generate current in
the circuit at milliamp level, in the case of alignment to the emitter ground,
only the neutral conductor can be connected. If the emitter connection is
made between phase and the protective conductor, the functional safety of
the production conductor must first be tested, in compliance with DIN VDE
0100. The reason is that when connecting the -Continues-

emitter from between phase and earth, all parts that are connected to earth
could be live generating a fault (if the earth resistance does not comply
with the prescriptions).
•If user protection is not ensured, the instrument must be taken out of service
and its use avoided. Safety is not guaranteed if the instrument:
- shows obvious damage
- does not carry out the desired measurements.
- has been stored for a long time under unfavorable conditions.
- has been subjected to mechanical action during transport.
•The instrument will only be used under these conditions and for the purpose
for which it was designed. When the instrument is modified or changed,
operational safety is not guaranteed.
Caution!
•The operating temperature of this cable locator is 0-40º C (32-140ºF)
•To avoid damage, this device must be protected from excessive mechanical
vibrations during transport or use, especially from drops.
•Only professionals are authorized to calibrate and repair this instrument.
•Before use, inspect the instrument and the test lead in use for external
damage. Please make sure the instrument and the test lead are intact. The
instrument must not be used unless all the functions of the apparatus are
well prepared for operation.
•When using the instrument, the nominal voltage of the circuit to be tested
must not exceed the voltage indicated in the technical specifications of this
cable locator.
•Keep the instrument away from sun exposure to ensure its perfect
performance and a long life.
•If the instrument is subjected to a high electromagnetic field, its functional
ability may be affected.
•Use only batteries as indicated in the technical data section.
•Try to keep the battery away from moisture. If the display shows a flashing
battery sign, the batteries should be changed.

Recommendations
•Before using a locator that has been located or transported under extreme
weather conditions, please place it in a favorable environment for a period
of time.
•When the emitter is connected to the network, if the emitter earth is
connected to the protective earth, the leakage current (if any) in the power
supply can add to the current of the emitter circuit, leading to dispersion to
the circuit breaker, eg FI / RCD trip.
•Please keep the original packaging for later shipments (eg for calibration of
the device).
1 DESCRIPTION
1.1 Product introduction
When drilling a hole in the wall to install an air conditioner or in the ground for
installing a machine, or when digging in a road, you need to know the routing
of the cables, water or gas pipes in the wall or the ground to avoid
unnecessary damage and even dangerous situations.
In the past there was only one solution to this situation, which was to find
the construction plans for these installed services. However, in the majority
of cases, these plans were not accessible and the risk of interruption of
cables or pipes had to be run, carrying the consequent danger or failure of
supply, electric shock, explosion, or danger of death.
Now with this cable locator developed by our company to effectively help
users locate or detect cables, you don't need to take any more risks.
This cable locator is a portable instrument consisting of a transmitter, a
receiver and various accessories. With advanced integrated parts and
digital technology circuits, it is characterized by its reliable and safe
electrical performance. The emitter sends AC voltage modulated by digital
signals to the target wire (or metal pipes), which generates an alternating
electric field; -Continues-

place the receiver sensor head close to this electric field and the sensor will
generate induced voltage. This instrument can magnify a weak voltage signal
hundreds of times and then display it on the monitor after decoding the audio
frequency, demodulating and performing digital processing, so that the
position of buried cables or pipes, as well as their faults, can be detected
based on signal change.
This cable locator is easy to use and provides comfortable operation by
means of buttons, which indicate a correct press by emitting buzzes. In
addition, the screen allows visualization and the transmitter and receiver are
equipped with LED lights.
The emitter not only emits signals but also acts as a voltmeter, in this way the
instrument can display the voltage of the tested line, including the AC / DC
differentiation, apart from showing a warning symbol when checking an active
line. The sender is also provided with a self-inspection function, which notifies
on the screen if the sender is transmitting signals, making the users more
confident in the checks.
The receiver display is backlit, so users can see test results even in the dark.
To improve the efficiency of the test, the receiver is equipped with a
loudspeaker, which will emit changing tones as the signal strength changes,
in this way users can judge the effects of the test simply by the sounds, to
your greatest comfort. To adapt the instrument to a noisy environment, the
speaker emits a loud sound. Of course, both the transmitter and the receiver
have a mute mode to avoid discomfort during use.
The cable locator is applied in construction involving telecommunication
cables, power cables and pipeline construction, as well as the maintenance
of such cables and pipes.
