My scale needs to be recalibrated. Problem is I need a 200 gram wieght. The store near my house doesn't have them (They should. They sold me the damn scale) and ordering online is out of the question. Anyone know anything that weighs exactly 200 grams? On aside note, I tried measuring it out with 1 cup of sugar (Supposedly right around 198-200 grams and I got it to where it comes within .2 grams accuracy per gram. (Meaning when I put something on that wieghs 1 gram it reads 1.2. When I pet something on that is 5 grams it reads 6 grams. And it won't let me calibrate it again. I've tried adding sugar, and subtracting suggar, but it always stays right around .2 off per gram. Any ideas?
