SeekTech SR-60
Glossary -- Definitions
Operating Screen
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.
Passive Line
Tracing
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 conductors reflecting transient RF energy, etc.
Pole
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.
Proximity Signal
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.
Race Track
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.
Signal Angle
The field angle measured relative to the horizontal plane.
Signal Strength
The relative strength of the total field signal detected by the lower Omnidirectional
antenna in three dimensions.
SimulTrace ™
An advanced locating mode which makes it possible to simultaneously trace a
pushcable emitting a 33kHz signal and also detect a 512k Sonde when it comes in
range of the locator.
Sonde
A self contained transmitter, often battery-powered, which is used to signal a point within
an underground pipe, tunnel, or conduit.
Tracing Circuit
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.
Watermark
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 indication of the highest signal detected. See Level Pointer.
