Uncanny interference w/ pH controller
I've read about controllers receiving interference from electronics; the pH display will suddenly go haywire and way off.
But I've got something different. In my stand there is a el cheapo strip light that I'm sure is powered by a magnetic ballast. With my SMS122 I noticed it will turn on early whenever I turn the strip light off. This happened 8/10 times. I tried all the other electronics around and the canister filters do the same thing, except 9/10 times. So I guess it is EMI since only magnet driven electronics do this.
The pH controller is tripped on ONLY when I turn the in-stand strip light or canisters OFF. Turning them on or their constant use doesn't affect the pH controller in anyway.
So this really is not a problem. The on-off cycle of the controller simply gets shortened one cycle and then returns to normal.
Just wondering, anyone else have this happen?
