There Are Several Possibilities For A Cable Locator In Complete Circuits - Amprobe AT-2032 Manual De Instrucciones

There are several possibilities for a Cable Locator in complete cir-
cuits:
1st Possibility (one pole application)
Connect the transmitter to only one conductor. In this operational mode, the transmitter is
supplied by the bulild-in battery. Due to the high-frequenzy signal generated by the
transmitter, only one single conductor can be located and traced. The second conductor is the
ground.
This arrangement causes a high-frquenzy current to flow through the conductor and to be
transmitted to ground, similar to a radio and receiver. As from now on, we will call the above
described operation one-pole application.
2nd Possibility (double-pole application)
Connect the transmitter to the mains. The transmitte is supplied by the mains. In this example,
the modualted current flows through the phase into the transformer and back through
neutral. There is a furhter possibility for voltage free systems by connecting the transmitter
to two line terminals while short-circuiting the other line ends. Thus a complete circuit is
created. Then, the transmitter is supplied by the build-in battery. From now on , we will call
this operation double pole application.
The Cable Locator can only detect or locate lines, etc. which are connected correctly in
accordance with the physical principle described.
