Selecting the Phased-Noise Reduction Filter

The default setting for the phased-noise reduction (PNR) filter is on (as indicated by the
check mark in the PNR menu below), and is used in all applications (conveyor
applications and gravity-feed and pipeline applications) to reduce background noise and
increase the ability of the search head to detect metals. In addition, the PNR filter
reduces the number of uncontaminated units of product that are erroneously rejected as
contaminated. The PNR filter can be used in conjunction with the CLX and QNR filters, if
needed.
