SeekTech SR-60

Glossary -- Definitions

Active Line Tracing

A mode of locating using a Line Transmitter to inject a chosen frequency onto a hidden

conductor; the frequency is then detected by the SR-60 to trace the conductor

Active View Area

The area within the circle in the center of the operating screen, where the Tracing Line

or Sonde Pole and Equator symbols appear.

Bleed over

Coupling of the signal from the target line onto adjacent conductors by any means

(resistive, capacitive, or inductive). Bleed-over makes the signal appear to be coming

from a different conductor than the one being traced by setting up a field of the same

frequency in a nearby conductor.

Checked-Active

Frequencies

A frequency is said to be “Checked-Active” when it has been checked on the main

menu; this enables it to be accessed by the use of the Frequency Key during operation

of the SR-60. The “In Use” frequency is always one of the Checked-Active set.

Clear Signal

A clear signal is a field caused by current through a conductor which is strong enough to

be detected unambiguously by a receiver such as the SR-60. Clear signals depend on

good conductivity, good grounding, and adequate current through the target conductor.

Clipping

The condition of receiving a signal too strong to be processed all at once by the signal

processor; in the SR-60 this condition will cause a warning signal to flash. The signal

peaks are too high and are “clipped” off.

Common Bonding

The use of a connector to ground more than one line through the same ground

connection. Phone lines, for example, are often bonded to ground via the electrical

service ground line. Common bonding can be a cause of ambiguous signals in locating.

Compound Field

An electromagnetic field caused by the combination or two or more fields in proximity to

each other. A compound field has multiple lobes and a complex energy pattern which

can require analysis to interpret correctly when locating.

Coupling

The transfer of energy (without direct electrical contact) between two or more cables or

components of a circuit. This can occur through induction, through common bonding, or

other means.

Crosshairs

A symbol in the center of the Active View Area representing the location of the SR-60,

relative to the detected field.

Current Strength

The calculated level of current based on field strength detected by the Omnidirectional

antennas of the SR-60; expressed approximately in milliamps (mA). An accurate depth

measure is required for accuracy.

Currently Available

Frequencies

Frequencies which have been checked in the Master Frequency Menu are said to be

“Currently Available”; they appear on the Main Menu when the Menu Key is pressed,

and can be set to “Checked-Active” status.

Default

Default values are those settings which the SR-60 uses if the operator does not choose

alternative settings; they can be restored from the Information Menu.

Depth

See “Measured Depth”
