NGA 21 Locating And Marking Of Facilities Practice Test

Which statement best describes the role of the receiver in a locating system?

It powers the transmitter It converts the induced voltage into visual and audio signals for location It creates the magnetic field around the pipe It substitutes for the earth stake

Correct Answer:

It converts the induced voltage into visual and audio signals for location

Explanation:

In locating systems, the transmitter energizes the line, and the receiver’s job is to sense that energy and translate it into usable cues for finding the pipe. The induced voltage or magnetic field generated by the transmitter is picked up by the receiver and then converted into audible beeps and visual indicators, telling the operator where the line runs and where to dig. This conversion to easy-to-interpret signals is what makes the location practical and accurate. The other described roles belong to different parts of the system or are not functions of the receiver: powering the transmitter, creating the magnetic field, or replacing the earth stake.
