Measuring line noise and power conditioners


I recently purchased a Trifield EMI (Dirty Electricity) Line Meter to measure noise coming from my outlets. To my surprise, my $500 power conditioner (name withheld to protect the potentially innocent) appears to not filter any noise per the Trifield readings. In fact, with some of my outlets the measures are higher through the conditioner’s outlets, than the measures coming straight out of the wall. The manufacturer denies anything is wrong with their conditioner, claiming the Trifield is measuring the wrong frequencies. Can anyone explain?

The audience here simply doesn't know much about noise, including the people fronting noise reduction technology. The subject is codified in many ways by many international organizations. It is based on a knowledge of mathematics and of many other areas of engineering. Because we are supposed to be an organization of music lovers, add our group to the subject of "noise." It isn't nearly as codified and regulated, but still covers a wide area of human reaction to sound.
I am not going to say anything other than that "stupid is as stupid does." If you would like to really understand noise, it's measurement and appreciation, start with yourself. As a human being, interested in music... learn to appreciate the music, not the noise. The best filter I know is your mind. "If you don't mind, it doesn't matter."
