Some of this is hard to explain, and perhaps worth figuring out.
So if you plug in the Power Sentry, the reading on the Entech goes up?
But then you plug the vacuum into it and the reading is lower than baseline?
Does the vacuum bother you, and does it have a variable speed motor or any
electronics? Does the Power Sentry have a display or any controls?
The fact that your background drops when plugging in a filter
makes sense... this is from the capacitance. But that also means
there is current flowing from the device to the filter, which could
make matters worse for humans unless you are far away.
I suppose when the readings go up from plugging in the filter it is
either from a resonance or from active electronics in the filter.
I was a bit surprised how if I plug the Entech in close to the DSL router
I can hear a buzz, but if I plug it in far away (another outlet on the same
phase) I don't hear it and the reading is lower. So the impedance of the
wires matter.
