SeekTech SR-60
• Guidance Line Shows the alignment of the
target line and helps determine when the
locator is directly over the target line. It will
be longest when directly aligned with the
target line. Rotation Arrows will appear to
indicate which way the SR-60 should be
turned to align it with the field.
Note: The Tracing Line reflects the approximate axis
of the conductor being traced, but is modified by a
degree of “distortion” in the form of varying
cloudiness, or loss of focus, in the Tracing Line. The
Tracing Line will appear to grow unfocused in
proportion to the distortion in the field being detected.
It ranges from a clear line (no distortion present),
through slightly distorted, to moderately un-focused,
growing to a wide, cloud-like band of particles
depending on the degree of distortion in the detected
field. It represents the best possible calculation of the
location and bearing of the line combined with the
degree of distortion sensed by the receiver’s
Omnidirectional Antennas.
When the distortion response of the tracing line is
turned off, a separate Distortion Line will be
displayed. The Distortion Line can be used to analyze
distortion when it is out of alignment with the Tracing
Line. (The dashed line can be disabled separately, as
well, which will leave a single Tracing Line displayed
with no distortion response).
The default setting is to have the distortion response
enabled in the Tracing Line. This incorporates the
information provided by these two lines into a single,
easy-to-read presentation, making the SR-60 easier
to use.
(For more information about distortion, see pages 33
and 39.)
Note: The screen elements in Passive Trace Mode
are the same as those seen in Active Line Trace
mode. Mode is determined by the type of target
source (Sonde or Line). For example, selecting the
512 Hz frequency from the Sonde mode section of
the frequency menu puts the SR-60 into Sonde
mode. (A frequency which appears in more than one
category, such as 33 kHz, must be selected from the
correct category).
Display Elements: Sonde Mode
Figure 6: Display Elements: Sonde Mode
In Sonde mode, the screen elements include several
features that are unique to Sonde locating.
•
Signal Strength – Strength of signal as
sensed by the lower Omnidirectional
antenna.
• |
| Pipe Direction – Represents the
approximate direction of the pipe in which the
Sonde is lying.
•
Sonde Icon – Appears when
approaching the location of a Sonde.
•
Equator – Represents the mid-line of
the Sonde’s field perpendicular to the axis of
the Poles. (See page 26).
•
Pole Icon – Represents the location of
either of the two Poles of the Sonde’s dipole
field. (See page 26).
•
Zoom Ring – Appears when the locator
moves close to a Pole.
The use of these features is described in the Active
Line Tracing, Passive Line Tracing, and Sonde
Locating sections.
Default Frequencies
The Master Frequency Menu contains a large set of
frequencies, but only some of these are made
currently available. They are made “Currently
Available” by checking them in the Master Frequency
Menu.
The frequencies which are currently available will
appear on the Main Menu when the Menu Key
is
pressed.
Currently available frequencies can be checked in the
Main Menu, in which case they will appear when
using the Frequency Key
. If they are unchecked in
