If it won't calibrate as PE suggests, then that scale is defective; is it too late to return it under warranty? I have two scales from AWS (American Weigh) bought via amazon, and both work fine and agree with each other. But I'll admit that the more expensive milligram scale (.001 resolution) glitched once, creating a mystery brew that worked great but I can't reproduce.
