Just thought this was important to those who can't afford a very expensive scale.
With my own milligram scale ($20+shipping), it keeps on wanting to go back to zero if it's close to zero.
So I turn my scale on without the tray. Then I put the tray on and I don't tare it. I write down the weight shown (2.500).
Then I can put about 10mg on and it shows 2.510.
I then calculate the difference (10).
Seems to be +/-1-2mg on the cheap Gemini.
This scale has a laser-pointer battery super glued to the weighing platform, super glued to a plastic tray
1. Super-Glue a battery from a laser pointer with a
2. Flat piece of plastic from a plastic container, and next to it are
3. Shot cups from Party City
I found a q-tip and a dab of acetone cleans it up really nicely.
