4.3 Optional connections to the cable locator
4.3.1 Single-pole use
The transmitter is connected to only one conductor. Due to the high frequency signal generated by the
transmitter, only one conductor can be located and tracked. The second conductor is the ground. This
arrangement produces a high-frequency current which flows through the conductor and is transmitted to
the ground, similar to a radio or receiver.
4.3.2 Two-pole use
The transmitter is connected to a conductor with two test leads. This method can be used with both
current-carrying and voltage-free cables.
Current-carrying cables
Connect the "+" opening of the transmitter to the phase of the mains cable and the ground opening of the
transmitter to the neutral conductor of the mains cable. In this case, if the mains cable is not loaded, the
modulated current goes from the transmitter via coupling through the distributed capacitance in the mains
cable to the neutral cable and then returns to the transmitter.
Voltage-free cables
Connect the positive output of the transmitter with a mains cable. Connect the ground output with another
parallel mains cable. After that, the modulated current returns directly through the mains cable to the
transmitter. Optionally, both test leads of the transmitter can be connected both ends of a conductor.
Also, the positive output of the transmitter can be attached to the connector of the mains cable, if the
grounding output of the transmitter can be connected to the protective grounding connector of the mains
cable.
5 Operation
5.1 Single-pole use
5.1.1 In open current circuits
-
Detecting and locating cable breaks in walls and floors
-
Locating and tracing cables, sockets, junction boxes, switches, etc.
-
Locating bottlenecks, kinking, buckling and obstructions in pipes with the help of a metal wire
Make sure that the protective ground cable is working properly.
The use in the open circuit is suited for finding current-free sockets and switches.
The tracking depth depends on the medium and application. Typically, it is between 0 and 2 m. The
protective connection of the socket can be used as a ground connection for the transmitter.
