Product Compensation
These so called locus plots can give us a valuable understanding of how the
metal detector works, and how it must be set up for optimum performance in
different applications. Consider Figure 5, which shows the locus plot both for a
tub of frozen ice cream and a 2mm Ferrous sample. In this example, if the
control unit is set to look at the R signal only, then when the R signal increases it
must be due to contamination, as the ice cream gives little R signal.
