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 for further details.
