I bought a Lyman 1200 DPS II in February of 2005. This scale has always performed flawlessly for me throwing charges within +/- .10 grain. Then it recently started throwing charges that varied by 8/10 grain when checked against my old Ohaus 10-10. I called Lyman about the problem and was told it was likely a static issue and was prescribed the following fix.
1. Saturate a towel with Windex. I used paper towels and the bottle I bought at the store reads Windex Original with ammonia-D
2. Wipe down everything on the scale inside and out without dis-assembling anything and let the unit air-dry.
3. Do this a total of 3 times.
I did exactly what they said to do and I did it it exactly how they said to do it. The procedure immediately solved the issue and the scale is back to working the way it always had. Just putting this post out there because I remember more than a few members were having the same problem with their electronic measures and scales.
