I feel the same way. I dont trust my RCBS electronic. I have to watch it real close. It will start to read on the plus side for no reason after a few loads. I have sat and watch the tenths go up with nothing on the scale. I trust the balance beam a lot more than I do the electronic.
Maybe you could look around the bench for some of the items spoken of in the link, unclenick covers a lot of it in one shot.
Electronic Scale
We used to place
Ferrite cores on video cables where I work. I use the cores at home and a
UPS to prevent line noise issues. The UPS with Surge will protect those expensive home electronics. It is still possible for one to fail and equipment damage can happen.
A
Line Conditioner is used on my TV at home and something I would choose over a UPS if picking between the two. That would change to the UPS if you are are trying to save data on a PC or if you have a phone with your cable company or VOIP, it will keep the phone in service if the line is not damaged until the battery fails.
The Line Conditioner kept at a distance from the scale would be the best choice. The correct lighting and no fans. My 2 cents
