PERFORMANCE VALIDATION ROUTINE

General

The performance validation routine (PVR) helps
users comply with ISO 9000 and BS5750 by
ensuring that the metal detector system is tested
and operating to the users specified quality
assurance (QA) standards of performance.

The quality standards of may user companies
require the metal detector and its reject system to
be manually tested at specified intervals by
authorised QA personnel to validate compliance.

QA personnel may programme the detector to
indicate when testing is required and to give an
alarm if testing is not carried out at the appropriate
time. Individual QA personnel may be allocated a
private access code to the metal detector ensuring
that the individual charged with testing the metal
detector does so at the specified time.

Local Printer Unit (Optional)

Although effective as a stand alone function the
PVR is most effective when used in conjunction
with a local printer unit (LPU), the printer will
provide a date and time stamped hard copy print
out showing when the metal detector was tested
and by whom.

The hard copy print out can be used to demonstrate
authorised personnel’s compliance with company
standards and hence the user companies
compliance with the agreed quality standard. This
may prove invaluable to companies wishing to
demonstrate compliance with the ISO 9000,
BS5750, the UK Food Act, and for users supplying
the major retail organisations with strict metal
detector standards.

The LPU also records general information relating
to the metal detector performance, it will date and
time stamp events such as rejections and changes
made to the metal detector settings. The LPU is a
very useful management tool for recording events
that effect detector performance.

The customer may use their own LPU (providing
the module firmware is 2.10 or greater) or purchase
a Safeline LPU.

See Appendix D for illustrations of typical printouts.

Accessing The PVR

All Safeline metal detectors are shipped from the
factory with the following PVR access codes

Code 0004 = QA Inspector Access

Code 1000 = QA Operator 1 Access

Code 2000 = QA Operator 2 Access

Code 3000 = QA Operator 3 Access

–

ETC through to –

Code 9000 = QA Operator 9 Access

CONFIGURING THE PVR

Various operating characteristics of the PVR are
programmable and may be altered or configured to
suit the particular requirements of the application.
The configuration process should be performed by
the QA Inspector when first installing the metal
detector or making changes to the setup
characteristics.

On entering the QA inspector mode select
