Some scales with higher weight resolutions are susceptible to air currents and are
used inside a wind screen box. My Peregrines with a 0.00 resolution drifts if I run
my hand across it too fast. First several times I used them, I was having fits with
them bouncing around until I realized it was the close by furnace register blowing
hot air across the room. If you have a florescent light above your bench, replace
the tubes with the new LED tubes. They are not cheap but the cost of electric is nill
compared to the old ones. The only other thing I do is to plug the scales into an old
line conditioner I used on my computers.
