Hello, I don't know if you know about this. If not, please be aware that peak values of RF measurements rise every couple of seconds when you use background light of the EMF-390 display.
I currently use two devices. The new one, Revision 3.75 measures peak values of up to 30µW/m² higher than it does when background light is off.
An older model (revision 3.72) has peak readings of up to +10µW/m² with active background light, compared to switched off background light.
The devices are still very helpful, I switched off background lights.
However, I would like you to keep an eye on this. I could not make sense of my readings and and I was 'hunting ghosts' because of this effect.
Now, since I do not use background lights anymore, the readings make sense.
Thank you for this great device.
