Buy a real scale and you don't have to think about all that.

I have never found one short of laboratory-spec equipment that is resistant to interference from electrical equipment that generates RF energy. I have a quite expensive kitchen appliance with built in scales that has apparently been built with shielding - can't use the scales with the microwave being used as the reading wanders approx 40%. That device is worth a lot more than the expensive reloading scales, and the set of reloading scales I have here are in the $1K range. It is just the nature of the beast with them, the generated resistance value of the load cell varies with position on the device and temperature of the remainder of the unit's guts even if the load cells are temp-compensated...

CFL bulbs, LED bulbs and the like with electro switched power supplies all generate the pesky RF interference that can cause wandering zero and wandering readings - on something like reloading it pays to be aware and check. The other ones that can cause issues is static electricity build up, or even air currents moving in the work area.

I don't often have an issue with the set I have here, but I check in between each powder weighing and that way I know if I need to rezero. Takes vary little effort (a large magnum case with the exact weight written on it or even a small lead sinker will do) - plunk it on and make sure the reading matches, job done.
