Well, I don't know if this would apply but I work in the electronics manufacturing industry and static electricity is a BIG deal. ESD, electrostatic discharge, can kill or damage lots of parts these days. Being winter and the ensuing low humidity makes the problem worse.
What we do is to have everything grounded to a common point. The tables have a conductive mat that is in turn grounded. Some areas will have a conductive floor mat, again grounded. Even the floor has conductive/dissipative wax on it. We all wear heel-straps that dissipate static charges to the floor mats and we also wear smocks and wrist strap, the latter plug into the table mats, to further protect the parts.
In a nutshell, you might need to employ some of these tactics or a variation of them to reduce the static build up on your scales and whatever other tools you use. I suspect too that you may need to get the humidity up in your work area. I may be way off subject as to you question but I suspect the problem is much the same as what I deal with.
