1. OVERVIEW
1. The working temperature of this Cable Locator is 0-40°C (32-104°F).
2. To avoid damage , this device should be protected against excessive mechanical
vibration during handling or use, especially dropping.
3. Only professionals are allowed to calibrate and repair this instrument.
4. Prior to usage, inspect the instrument and the test lead in use for external damage.
Please ensure that the instrument and the test lead in use are intact. The instrument
should not be used unless all the functions of the instrument are well prepared for
work.
5. When using the instrument, the rated voltage of the tested line should not exceed the
rated voltage specified in the technical specifications of this Cable Locator.
6. Keep the instrument off direct sunlight to ensure perfect functioning and long service
life.
7. If the instrument is subject to an extremely high electromagnetic field, its functioning
ability may be impaired.
8. Only use batteries as described in the technical data section.
1) Before using a locator that has been placed or transported under extreme climate
conditions, please place it under a new favorable environment for a certain period.
2) When the transmitter is connected with live mains , if the Grounding hole of the
transmitter is connected with protective ground phase, the current leakage (if any) in
the power supply line may join the circuit current of the transmitter, leading to tripping
of the leakage circuit breaker, i.e. tripping of FI/RCD.
3) Please maintain the original package well for later mailing (such as for calibration
of the instrument).
1.1 Product introduction
When you are making a hole in the wall for installation of an air conditioner or on the
floor for installation of a machine, or excavating a road, you have to know the layout
of the cables, water pipelines or gas pipelines in the wall or ground to keep away from
these facilities and avoid unnecessary troubles and even dangers. In the past, there is
only one solution for this issue, that is, to find the construction drawings of these
embedded facilities. However, in most cases, these drawings cannot be found and you
have to take your chance, which may result in interruption of cables or pipelines,
bringing about the danger of power failure, electric shock, explosion or threat to life.
Now, with this NF-826 Cable Locator developed by our company to effectively assist
users to locate and detect cables, you no longer need to take your chance.
This Cable Locator is a portable instrument consisting of a transmitter, a receiver and
some accessories. With advanced integrated parts and digital circuit technologies, it is
characterized by highly stable and reliable electrical performance. The transmitter sends
to the target cable (or metal pipes) an AC voltage modulated by digital signals, which
generates an alternating electric field; Put the sensor head of the receiver close to this
electric field, and the sensor will generate induced voltage. This instrument can magnify
this weak voltage signal by hundreds of times and then display it via an LCD screen after
audio frequency decoding, demodulation and digital processing, so that the position of
the buried cables or pipes, as well as their faults, can be detected based on the change
of the signal.
This Cable Locator is user friendly and provides convenient operation by means of
keystroke, which can indicate effective pressing through a buzzer. Besides, the display
is visualized and the transmitter and receiver are equipped with LED lamps. The
transmitter not only transmits signals but also acts as an AC/DC voltmeter, so that the
instrument can display the voltage of the tested line, including the AC/DC status, in
addition to a warning symbol when testing a live line. Besides, the transmitter is also
provided with self-inspection function, which is realized by showing in the display
whether the transmitter is transmitting signals, making the users more confident in
testing. The display of the receiver has backlights, so that users can see the testing results
even in darkness. To improve the testing efficiency , the receiver is equipped with a
loudspeaker, which will give changing tones at the time of changed signal intensity, so
that users can judge the testing effects simply by sound, leading to enhanced convenience.
In order to adapt the instrument to a noisy environment, loud sound is used by the
loudspeaker. Of course, mute mode for both the transmitter and the receiver is provided
to prevent them from disturbing others when the instrument is used.
This Cable Locator is applicable for construction involving telecommunication cables,
power cables and building pipelines, as well as maintenance of such cables and pipelines.
