I bought this MICCA digital scale from amazon last winter.
After some puzzled feedback from other members re my ball weight, I tried to do some benchmark testing. I looked up the gram weight of 8 oz (1 cup) water. According to reference, it should be 236g.
I get 73g. Yes, I am using the tare function. This happens every time I try it, regardless of whether the unit has powered on, off, replaced batteries, etc.
Looking at oz weight, I get 2.55 oz ... of course it should be 8 oz.
No wonder I've had trouble duplicating other people's efforts. My own efforts have been reproducible - but only because I have been using my own "scale of measurement". At this point I have no idea what my ball weight is - the only thing I can be sure of are my percentages of ingredients. Even that is problematic, because I can't be sure that small amounts are being read correctly.
Does anyone have any idea how to calibrate one of these scales? I'm stuck with this thing for the foreseeable future.
