Conquest 100 Principles of Operation
The PCD sensor maps the location of current-carrying cables by detecting the magnetic field
created by AC current flowing (Figure 2-9) at 60 Hz (North America, parts of South America,
Philippines) or 50 Hz (Europe, Asia, Australia). Ensure this setting matches the standard for the
country you are in.
Like the GPR itself, PCD responses show up best when crossing the target perpendicularly
(Figure 2-10). When collecting a Line Scan (Figure 2-11) or a Grid Scan (Figure 2-12), both
GPR and PCD data are collected and displayed simultaneously.
