Is it possible to validate the measurements of a precise scale with a scale wich is less precise?
Let's say I have a scale wich can display values down to 1g and another scale which can display the values down to 0.01g. I measure for example 100 pieces, which I know are about 1g, on the precise scale an save all the individual measurements. Then I measure the total weight of all pieces on the less precise scale and write this value down. If needed, I can make as many measurements as needed on the less precise scale and use all these measurements.
With the information gained, total weight and individual weights off the precise scale, what can I say about the accuracy of the precise scale?
