• Proximity Number . A number that reflects how
close the receiver is to the target line when in either
Active Line Trace Mode or Passive Line Trace Mode�
The Proximity Number is calculated based on the sig‑
nal received by the two Omnidirectional antennas� The
Proximity Number increases with signal strength and
also increases with decreasing depth�
• Proximity Threshold. A control which decreases pos‑
sible distortion by constraining the receiver's locating
range�
• Radio Frequency Broadband
es for signal energy within a specific range of frequen‑
cies�
• Signal Angle . The angle of the target line's field rel‑
ative to the horizontal plane�
• Signal Strength . The strength of the target line's
field signal as detected by the lower Omnidirectional
antenna in three dimensions�
• Sonde . A self contained transmitter that emits a di‑
pole field and is used to locate a point within an under‑
ground pipe, tunnel, or conduit�
• Target Line. The utility line that your transmitter is
connected to on a locate�
• Tracing Circuit. The complete flow of electrical cur‑
rent from the transmitter through the conductor and
back to the ground� Weak current will cause a weak
signal�
• Tracing Line Distortion Response. When the Tracing
Line appears fuzzy because distortion is present�
