Many BPL people use a small digital scale to weigh their new equipment items. Many such scales have an auto-zero feature upon startup. However, to determine the linearity of a new scale, I wanted to measure some standards.
Toward the low end, a standard new U.S. Quarter coin weighs 5.670 grams. Mine passed that OK.
Now I'm looking for some standard closer to one pound (the top end for this scale). Any suggestions, besides a roll of quarters?
A pound of some food item is very inaccurate, because there are unknown wrappers involved.
