Well, it seemed every time I bought something, the weight my scale indicated was significantly higher than the manufacturer's advertised weight. Consistently so that I began to doubt the accuracy of my scale. I mean, just because it's "digital" doesn't mean one should have any to expectation for it to be calibrated. And buying a scale at the local kitchen and bath big box store doesn't instill the same confidence as buying from a scientific equipment supplier ...
I became hesitant to raise hell with manufacturers, or to even to post weights in my blog. So I ordered a three scale calibration weights that provide a nice range around that of the items I'm generally reviewing:
These results show the scale is just about spot on. At the 500 grams, it indicates 1g heavy. Overall, it validates my screeds, and that makes me happy.
