Conquest 100 Line Scan
62
Figure 6-5: The Line Scan screen. The Line Scan image is displayed with a position scale along the top, and a depth
scale (based on the current Concrete Cal) on the left. The PCD response is plotted as a red graph underneath with
the maximum scale value (in nT) displayed as a red number on the left. The DynaQ status is shown beneath that.
From Principles of Operation ( Section 2), you will have a sense of the information that you will
see on the screen. Flat boundaries such as the bottom of the concrete will appear as flat bands
and localized features such as rebar and condui
ts will appear as inverted V’s (hyperbolas).
6.3 PCD (Power Cable Detector) Response
The PCD response is displayed as a red graph under the Line Scan image. The PCD graph
indicates the strength of the magnetic field produced by AC current flowing near the Sensor
Head. Strong peaks may indicate the presence of a cable with flowing AC current.
The PCD scale is displayed in red below the PCD label. The units are nanoTesla (nT) and it
defaults to 100. If the magnetic field exceeds the maximum scale during collection, it will scale
automatically and the new maximum value will be displayed in red.
6.4 DynaQ Index Bar
Conquest uses DynaQ, an advanced patented technology that adjusts data quality as the
Sensor Head movement speed varies. In most situations, moving the Sensor Head at a
comfortable speed generates data of good quality. In situations where target resolution or
maximum penetration depth is critical, moving slower increases data quality.
As the Line Scan data scrolls on the screen, the DynaQ Index Bar is displayed along the bottom
of the screen (Figure 6-5).
The color of the bar indicates the quality of the data at that point along the line:
