I had questions similar to others on the efficacy/limitations of power cords and conditioners so I ordered an Entech wideband power analyzer. It seems to function, but I'm wondering if it's working correctly.
When I plug it into an unfiltered outlet I can only adjust the gain to a max of ~60. When I turn on "noisy" devices (ultrasonic record cleaner, coffee pot, coffee grinder) on the same circuit the noise doesn't change. When I move it to a filtered line with an aftermarket cord the reading drops about 10 points to 50, so the Entech seems to be measuring something. The instructions say you're supposed to adjust gain to 100, and the videos I've watched show the display around 100 and reductions of noise to <1 with filters.
Before I spend a lot of time characterizing things, is there a good way to make sure the device is working properly?
Thanks.
