Well I conducted another experiment and I'm even more confused here goes.

Took the scale over the kitchen granite counter tops which I know are solid and perfectly level (measured). Zero'd the scale and charged case number 1. Charged another case, #2. Measured case 1 and it was off high. Measured case 2 and it was perfect. So charged another case, #3. Measured case 2, came in low. Measured case one came in high. Measured case 3 it was perfect. Ok so I follow BC's recommendation and I placed the three new measuredpan charges onto paper plates and conducted the same experiment above. charge 1, charge 2, check 1, check 2 etc all the way up to three charges. They all measured perfect. So I'm thinking it's the brass. Well I doubted it so I then took the charges and placed them intothree brass. Some the same brass as earlier some new pieces. Did the measure test and they were all perfect, dead on. Still doubtedand did the test again and again that all measured dead on.

What the heck is going onhere?
