Appendix A: Glossary of Terms

• Active Frequencies. A frequency with the box
checked on the Main Menu
frequencies press the Frequency Key
• Active Line Tracing
line transmitter to induce a chosen frequency onto a
line� The receiver traces the line by detecting the fre‑
quency�
• Active View Area. The area inside the circle in the
center of the display screen� The Tracing Line, Sonde
Pole, and Equator symbols appear in the Active View
Area�
• Bleed Over. Bleed over happens when the frequen‑
cy from the transmitter couples current onto nearby
non‑target lines� The SR‑24 can receive the same fre‑
quency on multiple non‑target lines�
• Clear Signal. When the receiver detects a strong, un‑
distorted current flowing on the target line� A clear sig‑
nal depends on good conductivity, good grounding,
and adequate current through the target line�
• Clipping. When the signal is too strong to be pro‑
cessed all at once by the SR‑24's signal processor�
When clipping occurs, a warning flashes on the screen�
• Common Bonding. When more than one line is
grounded through the same ground connection�
Common bonding can cause the same active frequen‑
cy to be coupled onto non‑target utilities� �
• Coupling. The transfer of energy between the target
utility and other non‑target utilities�
• Cross Hairs . The symbol that represents the re‑
ceiver's location relative to the field of the target line�
The cross hairs appear at the center of the Active View
Area�
• Current Measurement (mA). The level of current in
miliamps based on the field strength detected by the
Omnidirectional antennas and the measured depth�

�
. A mode of locating using a
• Distortion. The impact of nearby fields, near‑by con‑
ductors, magnetic flux, or other interference on the
circular electromagnetic field� Distortion is detected
by comparing the information from the Tracing Line,
Proximity Number, Signal Strength, measured depth,
and Signal Angle readings from the upper and lower
antennas�
• Distortion Line. The dashed line that appears in the
Active View Area when the Tracing Line Distortion
Response is disabled� The Distortion Line indicates
the location of the target utility measured by the Upper
Antenna� Use the Distortion Line to visualize distortion
in the detected field�
• Frequency. The number of times per second that an
electromagnetic field forms and collapses� Frequency
is expressed in hertz (Hz) or kilohertz (kHz)�
• Guidance Arrows
Active View Area that indicates where the target line's
field is balanced�
• Level Pointer. A solid pointer that moves around a cir‑
cular track to indicate the Signal Strength detected�
• Measured Depth. The calculated depth, distance to
the Sonde, or the apparent center of the target line�
Potholing may be required before excavation to deter‑
mine accuracy of the target line's physical depth�
• Omnidirectional Antenna. Proprietary antenna tech‑
nology capable of simultaneously detecting electro‑
magnetic fields on three axes�
• OmniSeek . A Passive Line Trace Mode that
®
searches all power and radio frequency bandwidths
simultaneously�
• Passive Line Tracing
does not require a transmitter to place a current on the
line� The SR‑24 is able to locate by receiving current
through the target line from an external energy source�
• Pole . Represents where the field lines from the
Sonde vertically exit the ground� One of the two ends
of a dipole field�
. The arrows icon in the
. A mode of line tracing that
