Using Performance
Validation

Introduction

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. 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 prompt the operator to perform quality
assurance checks on a regular basis, and it then prompts the operator through a sequence
of tests using standard test samples. At the end of the Performance Validation test the
results are transmitted to a PC or printer to produce a printed copy of the report.
A typical PV Test report is shown below:
