Omniseek Locating - RIDGID SeekTech SR-60 Operator's Manual

SeekTech SR-60
In general, directly connected Active Line Tracing is more reli-
able than Passive Line Tracing.
WARNING
In Passive Line tracing, or when signals are extreme-
ly weak, the Measured Depth will generally read
too deep, and the actual buried depth may be much
shallower.

OmniSeek Locating

The SR-60 has an advanced capability for passive locating called
OmniSeek. The OmniSeek mode
mode that can simultaneously detect frequencies in three passive
search bands (<4 kHz, 4 - 15 kHz, and >15 kHz). Whichever signal
has the highest Proximity
to sweep an area without having to switch between frequency
bands.
To use OmniSeek, select it from the Main Menu:
Figure 30: Selecting
The SR-60 will then search all three passive frequency bands si-
multaneously. The trace with the closest proximity value will be
displayed more prominently on the screen, and its correspond-
ing frequency will appear on the left of the main screen. The
OmniSeek symbol on the screen indicates the other filters
are also running. If a closer proximity is detected from another
frequency band, the displayed frequency value will shift to that
band.

The display will show the main tracing line and identify the band
in which it is found. In Figure 31, the <4 kHz band is being dis-
played as the closest signal being seen by the locator. Notice
there is also a dashed secondary tracing line being shown. If
signals are also being detected from other frequency bands,
dashed lines (called Secondary Trace Lines) will indicate their ap-
parent location.

15 - 35 kHz Band
In Figure 32, the Tracing Line, in the<4 kHz band, is showing some
distortion. Two other signals are being detected in the bands
15 - 35 kHz and 4 - 15 kHz. If the operator wants to follow these
secondary signals up more closely, he can switch to the particu-
lar bands to see which one is being picked up in each band.
This enables you to do a Passive Locate more effectively if there
is, for example, a lot of 60 Hz noise in the environment. It is im-
portant to keep in mind that what you are seeing are traces of
signals from the various broadband frequencies. The operator
has to use the data to develop an understanding of what he is
seeing. If one or two secondary tracing lines are showing out of
alignment with the main tracing line, this can be an indication
of another utility, especially if it is at a deeper depth. But it can
also be due to simple signal energy on the same utility in differ-
ent frequency bands. Often greater distortion will be present on
other frequencies bands and this may cause the secondary trac-
ing lines to appear out of alignment with the main tracing line.
