My presence is requested at a packing line checkweigher, I arrive to find several QCs and 2 managers manually weighing punnets of grapes on some scales then passing them over the checkweigher (a high speed conveyor/ weigher that's very accurate)...and there's a variance in the two weights.
'Look, the scales say 539g...checkweigher says 545g, sometimes more'
They're doing this over and over with different punnets....so I say...
'How do you know the scales are right ?'
...was the response....
I continued...'put a punnet on a different set of scales then checkweigh it'
They did....it weighed different from the first set of scales...and the same as the checkweigher.
'
They do...the QC dept.You should have a calibrated set of test weights for situations like that.
What make of weigher is it?They do...the QC dept.
They were using it doing a static and dynamic calibration but got distracted by the erroneous scales. Its amazing how easily people are unable to see beyond what APPEARS to be staring them in the face.
Says me, Mr perfectOCS, German. Moderately old now. One infeed belt, one weighing belt, one outfeed belt. One of the first things you check Is that the belts arent touching each other, that would immediately upset the weighcell.
The irony is we have loads of older, low tech scales...and they believed the weights they displayed...not the accurate checkweigher.
The other irony is, I can see how the QC workers could be confused, they are not highly skilled, just know quality issues with the fruit...but the managers, I'd have expected them to be a bit more on the ball.

My sister was given a Kindle one Christmas and I set it up for her so she could buy books. She chose a Nigella cookery book and clicked on 'Buy'. She then put the Kindle to one side and started doing something else.Me : handing mom my ipad, here you are they have them on Amazon, £15 cheaper than the one in the shop...
Mom : Oh brill, could you order me one and ill give you the money?
Me : Just get dad to order it...
Mom : But your Dad hasn't got an iThingy,
Me : I know but he has a computer.
Mom : oh ok, will he have 'The Amazon' on his internet as well then?
