# Validate precise scale with less precise scale

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?

• Using the less-precise scale you have made just a single measurement? If so, your job of validation is going to be very difficult. – rolando2 Mar 19 '16 at 21:30
• You can't say anything whatsoever about accuracy until you know the accuracies of the scale used for the measurements! – whuber Mar 20 '16 at 16:38
• @rolando2 i can make as many measurements with the less precise scale as needed. I added this fact in to the question. – jrast Mar 20 '16 at 18:32
• @whuber assume the accuracy is the same as the displayed value on the scale. – jrast Mar 20 '16 at 18:32
