Page 12: Options For Direct And Inductive Signal Coupling
RANSMITTER SETUP AND SIGNAL COUPLING 4.3 Options for direct and inductive signal coupling There are four methods of coupling the signal from the transmitter to the line: • Direct coupling to cables and pipes (see below) • Coupling using special connection accessories (see page 13) •... - Page 13 RANSMITTER SETUP AND SIGNAL COUPLING • Single-wire lines or pipes (with or without insulation against earthing) The distance between the earth spike and the ends of the connected lines should be as great as possible. Note: It is possible that the return current will couple to adjacent lines, which could result in these lines also being detected.
- Page 14 RANSMITTER SETUP AND SIGNAL COUPLING • Metallic conduit (with or without insulation against earthing) The earth spike and the conduit should be spaced as far apart as possible. Under certain circumstances, optimum positioning of the earth spike may require several attempts. •...

Page 23: Determining The Direction Of A Line
ETERMINING THE DIRECTION OF A LINE 7 DETERMINING THE DIRECTION OF A LINE Follow the steps below to determine the orientation of a metallic conductor: Step Action If the direction of the conductor is to be determined with the aid of the transmitter, couple the transmitter's signal to the metallic conductor in such a way that there is as little signal loss as possible and switch on the transmitter. -
Page 24: Determining The Depth Of A Line
This is particularly important if depth is measured using the manual method. 8.1 Depth measurement - automatic The Elcometer 701 receiver has an automatic depth measurement feature. This feature will only operate if the following conditions are met: •... - Page 25 ETERMINING THE DEPTH OF A LINE Step Action Rotate the receiver (through its own axis) over this location until the maximum signal strength is indicated. Result: The receiver is in line with the conductor when it is positioned where the signal is strongest, which is prerequisite for determining the depth of the line.

Page 27: Masking-Out Lines
ASKING OUT LINES 9 MASKING-OUT LINES Under certain circumstances lines at lower depths can 'hide' deeper, adjacent lines, thus making it more difficult to locate them. In such cases, the transmission characteristics of the transmitter can be fully utilised and the lines which have already been located can be masked out. -
