The "Current" means the current reading at the moment. It corresponds to the reading with dBm/Watts. Basically it's the same reading as large one but in power density(different unit of measurement).
Yes pW is picoWatts. And the density is milliWatts per square meter. And tells how strong the signal is.
It can be reset if you click the S3 button or try to switch back to EMF/EF. You dont need to switch back, just click once.
Guess I'm still confused. I'm in RF mode/watts. Screen shows 100pW signal - 640 MHz 4nW/cm2 (current window) 427nW/cm2 (next window) 490nW/cm2 (peak) If nW/cm2 represents power per unit area (power density) then what does the 4nW/cm2 reading in the current window mean? Why is the window labeled "current" if the other readings are also current? Thanks for your help.
Does this mean that the 4nw reading only applies to the 640Mhz signal and the 427nW reading applies to all currently received signals? Just trying to understand the difference between the two power density readings. Thanks.
