    just bought a 750 and let it sit for an hour zeroed it started loading and every time I put the pan back on it would gain .1 or. 2 grains,then I left it with the pan on and it just kept climbing I stoped it after it reached 2.2 grains.I thought it may be the florecent light on my bench so I moved it to another room but no diff. any suggestions?
