Long story how/why, but I was playing with a GQ-EMF390 meter (no, I'm not starting a COVID ghost-hunting service).
I don't think the meter is/was calibarated/working because it always show a mG of 2.8 anywhere in the house and it always shows a minimum of 6 V/M on the EF readings.
However, those will change if I place it over things like the electric stove's line and such.
The QUESTION:
Sitting in a room, pretty much any room in the house, I get a standing 6-11 v/m. If it's calibrated poorly I can see that, however:
Why would it spike, every 5 to 8 seconds, to anywhere from 37 to <=70 v/m. Perfectly timed?
My house has a history of prematurely burned out incandescent bulbs too, and after discussing with neighbors I've got an unusually higher electric bill than most of them. I'm disciplined with regard to lights, and even though we are in SE TX (twin HVACs) we run the floors based on time of day.
Is this fluctuating v/m indicative of a cleanliness issue with my mains?
A DMM says the receptacles are providing what you'd expect (+ or - a few)
