 3. GQ EMF EF Meter RF Spectrum Power Analyzer
 Does GQ EMF-390 show values that base on P(eff)?

Dear specialists
I am sorry, there were errors in my formulas. I take the formulas out but my question is the same.

GQ EMF-390 provides both, LF and HF measurements per second that I read out to perform analyses. Mathematically this is field strength in V/m and Power density in pW/cm² for one second.

In electrotechnics it is advised to calculate average values with a root square mean and not use the arithmetic mean to get the effective value of electric power.

Are measurements of GQ EMF-390 based on U(eff) and I(eff) or not?

I need that information for the calculation of average values.
(a) To get the average value in a time frame of 6 minutes, can I use the arithmetic mean (Sum/count of measured Values) or

(b) do I have to calculate the root mean square...
Square root of ( sum of squared measurement values / count of measurements )

Thank you.
Have a good day.
