Thermo Scientific DSP2 Installation And Operation Manual page 48

How often the detector should be tested must be decided by the user. If the test procedure can be designed to be simple it will
help ensure that the test will performed more frequently. As a guide it must be decided how much product would have to be put
on hold for re-inspection if a detector fails the test. Typically the minimum frequency is once per shift while other applications
require hourly tests be performed.
Record Keeping
All detector tests should be documented. If faced with a consumer complaint or litigation a complete record of test results and
procedures will be very useful. The following chart can be used as a base for a manual recording system. Automatic records can
be produced by using Goring Kerr's DSPNet communication software program.

NOTES /ACTION
Rejected Product Examination
If possible, product which has been rejected by the detector during production should be examined to establish the source and
type of contamination. This may lead to an improvement in the process equipment upstream from the detector. It is also useful
to display these contaminants so that all employees can see the benefit of the metal detector.
Automatic Record Keeping
To simplify test record keeping, the use of a computer communications system called DSP Net is recommended. This system will
automatically record all events occurring at the detector including when the test was performed, and its success or failure. This
record is kept for each individual detector connected to the network and can be viewed, stored or printed at the host computer.
Contact Goring Kerr for information about this product.
QA Test Request
This detector can be configured to request a test procedure be performed at given intervals. Refer to the section in this manual
called QA Test on page 39.
Assistance
If you require any further assistance in establishing the test procedure, test samples, or test recording, please contact Goring
Kerr.
