Hi all,
I have been working on an updated metal detection for my company and a 'one best way' system so all staff are following the same metal detection policy. However, I have been looking through retailer COPs and most seem to follow an order of testing as below:
(Well this is the order I think they follow as some aren't too clear?)
1a. Consecutive testing - with gaps - performed start, after breaks and end of shift
1b. Consecutive testing - with normal spacing - performed start. after breaks, end of shift and every 30 mns
2. Memory testing - performed start, after breaks and end of shft
3. Large metal test - performed start and end of shift
4. Fail safe testing - loss of air pressure, reject bin full, sensor failure etc - performed start, after breaks and end of shift
However, my question is - I feel fail safe system testing should come first as you want to make sure they are working before performing other tests?
If I am correct in reading the retailer COPs and this order is best practice, can someone please explain why?
Thank you.
