Glossary - Definitions
The display screen of the instrument as seen when locating. It includes an Active View area, where the
Tracing Line appears in Line Trace modes, and where Pole and Equator icons appear in Sonde mode.
It also includes Measured Depth, Signal Strength, Signal Angle, current and Proximity Signal values,
depending on the mode and choice of options in use.
A mode of tracing a line which does not use a transmitter to place current on the line. It is used when
tracing lines which are energized from external sources such as 50/60 Hz electrical cables or conduc-
tors reflecting transient RF energy, etc.
Where the field lines from the Sonde exit the ground vertically. One of the two ends of a dipole field,
such as the magnetic field of the Earth, or the field around a Sonde. The SR-60 displays a Pole icon
when it detects the Poles of a Sonde.
A computed signal which reflects how close the operator is getting to the target utility in Line Trace
modes. It is calculated based on the signal received by the two Omnidirectional antenna nodes of the
SR-60.
An optional circular track around the outside of the Active View Area in which the Level Marker moves
to show current Signal Strength graphically. It also contains the Watermark which shows the highest
level of Signal Strength reached.
The field angle measured relative to the horizontal plane.
The relative strength of the total field signal detected by the lower Omnidirectional antenna in three
dimensions.
An advanced locating mode which makes it possible to simultaneously trace a pushcable emitting a
33 kHz signal and also detect a 512 k Sonde when it comes in range of the locator.
A self contained transmitter, often battery-powered, which is used to signal a point within an under-
ground pipe, tunnel, or conduit.
The complete flow of energy from a transmitter, through a conductor, to ground, and from ground
to the transmitter. When the tracing circuit is compromised for some reason, a weak signal and poor
detection will result.
An optional display icon which shows the highest level of Signal Strength detected. It travels in the
Race Track and moves up when the Level Pointer reaches a new high point, providing a graphic indica-
tion of the highest signal detected. See Level Pointer.
