GDL-201

The Electrom Cable Tracer Model GDL-201 is comprised of two components, a low voltage, low frequency audio transmitter which sends a signal along the cables to be traced, and a hand-held receiver with headphones to follow the signal the length of the cables being traced.

When the transmitter leads are connected to two cable leads it will generate a signal, providing there is a circuit through either a load or resistive short between the two cables. If an open cable exists, the transmitter will not generate a signal to follow unless the open option is used. The open option amplifies the GDL signal to create a broadcast antenna of the open wire. When the receiver reaches the open, the signal will disappear.
