Introduction to F2042 cable locator
Most electrical technicians occasionally encounter the need to track cables or wiring systems. This job is very tedious and a waste of time. In addition, it is often necessary to determine which safety device is connected to a specific circuit, or to identify and track metal pipes, heating pipelines, or underground cables. New Fluke2042Cable detector is a specially designed multi-purpose tool used to assist users in such applications. Fluke 2042 Cable Inspection Instrument on Special Offer in Stock
Working mode
FLUKE-2042The cable detector includes a transmitter and a receiver. The transmitter provides a modulated AC voltage to the corresponding cable, which generates an electric field around the cable; The receiver is equipped with a coil, and if the receiver is placed near the corresponding electrical conductor, the flux lines will pass through the coil and enter the receiver. This phenomenon is also known as penetration coil. A very small voltage is generated in the coil, and the electronic circuit of the receiver calculates this voltage and displays it on the screen. Fluke-2042The special feature is that the signal sent is digitally encoded. This ensures that the signal can be clearly received by the receiver, avoiding any erroneous display caused by interference fields such as electronic fluorescent lamp ballasts or frequency converters.

Generally speaking, there are two different application principles.
Application without voltage
A typical application is to locate switches and junction boxes that are accidentally covered by wall paint. Almost anyone is familiar with this situation: installing switches and distribution boxes, and threading cables for new equipment. After brushing the wall with paint, not all the sockets can be found. In this case, it is sufficient to apply a signal to any wire in the cable that needs to be tracked. The other pole of the signal transmitter is connected to the ground potential through a grounding wire. Ensuring the dryness of building materials is very important Fluke 2042 Cable Inspection Instrument on Special Offer in Stock
End the hide and seek style of work
Fluke 2042 Cable Detector is a portable handheld instrument used to track hidden lines in walls, locate break points and short circuits in cables, associate electrical leads with circuit breakers, and track underground cables
Whether for residential or commercial applications, Fluke 2042 will save time and manpower for the installation of new electrical facilities and fault diagnosis of existing installations. The Fluke 2042 cable detector is exactly the tool you need:

Applications with voltage
It is common to encounter situations where there are no labels on the circuits of old systems. To avoid accidentally disconnecting the wrong power supply, it is necessary to match the correct safety device with the corresponding circuit.2042Cable detectors can also be used in this situation. Connect the signal transmitter directly between the phase and neutral lines. In this case, the signal detection strength generally decreases. The alternating voltage and the electrical flux of the signal transmitter will affect each other. However, in this case, the reduced tracking depth is not very important as the cable can be directly contacted at the open distribution box.

The process of locating cables
In order to successfully locate cables in this type of application, it is necessary to theoretically understand the principles of this working mode. Using a covered socket as an example for illustration. In this case, lighting sockets are often the only place where cables can be accessed. The signal from the transmitter is sent into the cable from the socket.
The connection method of the transmitter is as described in the above application scenario without voltage. The grounding point of nearby sockets or extension cords is used for grounding. Now, track the corresponding cable until no signal is received. The operator can manually adjust the sensitivity of the receiver, and depending on the depth of installation in the wall, the sensitivity on the receiver must be increased or decreased. Once a signal is received, the receiver will display the letter "F" and the strength of the received signal.
In addition, three different transmission strengths can be set on the signal transmitter. Track the cable in this way until it reaches the end and locate it to the corresponding junction box or switch box. Good grounding of the transmitter output signal is crucial for voltage free applications. There should be no signal received on the cable connected to the ground -
If the transmitter is connected to one end of the cable to locate the breakpoint, sometimes only the approximate location of the breakpoint can be determined due to magnetic field interference. In this case, using another transmitter with a different signal encoding would be very helpful.
For shielded cables, such as overhead cables, the signal will be displayed on the screen. Knowing the condition of the building structure in advance can also be helpful for this process. The steel bars in hard concrete also have a negative impact on tracking signals.
Reinforced concrete is highly likely to play the role of a grounding shield and will not receive signals. It is recommended to conduct actual testing on known systems before conducting on-site operations for the first time. This is a great way for users to familiarize themselves with the working mode of the instrument. Using specialized cable detectors to locate cables has multiple advantages in on-site testing. Using the trial and error method to locate cables, such as piercing through walls, can damage the structure of buildings and also damage the cables themselves. New Fluke-2042Cable detectors provide various forms of assistance for daily life. Fluke 2042 Cable Inspection Instrument on Special Offer in Stock
Accurately locate cable breakpoints using additional signal transmitters
Locate faults in electric underfloor heating
A very attractive application is to locate faults in electric underfloor heating. For example, when underfloor heating is just installed but cannot work properly. A common cause of this malfunction is that the floor where the underfloor heating is installed is accidentally cut or damaged. For heaters with protective layers, it is very important to be able to see the emission signal on the screen. Fluke 2042 Cable Inspection Instrument on Special Offer in Stock
