Good Morning,

The CSV File that can be generated with GQ EMF-390v2Re3.69 / Re3.61 contains a great column Possible Source that contains the following values:
'---'
'Static'
'Mixed'
'WiFi/Phone'
'AC EF'
'Cell Tower'
'Power Line'
'Smart Meter'



I would like to know based on what measures this column is generated.

These are my questions:
a) Is it frequencies that determine the content?
b) If so, could you please tell, what frequency ranges are used for each category?
c) Can EMF-390 identify other sources I have not listed?
d) If is it not frequency, what is it?
e) What does category '---' represent?

My Thanks,
Frank

Excellent, thanks.

The difference is in which Field dominates more. In Power Lines, the EMF usually reads higher readings and the EF is very low, while AC EF has significantly very high EF.

One question I forgot.

What is the difference between 'AC EF' and 'Power Line'?
Thanks.

Thank you.

Hi Frank, the possible source is based on all readings including EMF, EF, and RF.
--- means there is no radiation detected or cannot be determined.
