Is it possible to have a more accurate source description appear further away from the EF/EMF source? At present the meter only detects the correct source when literally right next to the emitting object. Thus, can get four different descriptions for a microwave oven depending if you've moved only a couple of feet away. eg. 'Microwave' oven also comes up as 'Power Line', 'Cell Tower' and 'Mixed'.
Is the source description based on how high the RF reading is; thus moving further away from RF emission gives lower RF reading and a different source description?
