4.23 Using Performance Validation
This section describes the benefits of the Performance Validation System and explains how to set
up the metal detector for PV testing, with information about each of the parameters that need
to be specified.
Regular checking of the metal detector’s sensitivity should be a normal part of any quality
assurance procedure. This is particularly important should it become necessary to demonstrate
due diligence to address customer or legislative requirements.
One approach is to make regular sensitivity checks and keep handwritten records of the results.
To assist in maintaining quality assurance controls the metal detector includes an automatic
Performance Validation System. This can be set up to automatically prompt the operator to
perform quality assurance checks on a regular basis. It then guides the operator through a test
sequence using standard test samples. At the end of the Performance Validation test the results
are saved in memory and can be outputted in a number of ways.
See the Logs and Reports section in the Reference Guide for further details.
