@sns funny guy. good to know when condescension is called for, you’re the go-to.
Surprised at Low Household EMI Readings
I picked up a Trifield EMI100 meter to check for EMI noise around the house. After watching a few YT vids I was expecting some pretty high readings. Surprisingly almost everything was low. The unfiltered outlets where my system is plugged in measure less than 10 milllivolts with all equipment powered on. The worst was the bathroom GFCI outlet at around 65mV. I use a 10-year-old Blue Circle power conditioner, and that output is a few mV less than the wall outlet. The house was built around 1970, and outside of a new fuse box installed a few years ago, everything else is original.
Very happy with these readings as I was considering a power conditioner upgrade. The $150 Trifield meter seems to have saved me a few thousand bucks.

I was led to believe that if I had low EMI then my AC power was fairly clean. Others here seem to think otherwise. Please elucidate if this is incorrect. What other nasties live might live in my power and how can they be detected? @sns not talking about RF @ghdprentice no plans to install new lines @dekay or bribed the admins to block you |
