Shift & Sweep the instrument in order to find the point of maximum exposure.
Simply shifting or moving the meter (using a slow sweeping motion in front of you)
will enable you to find the true maximum signal strength in that area. Since signals in
traveling through the air can sometimes cancel themselves out (just like opposing
waves in a pond cancel each other out resulting in the sum of the two being less than
either one), by sweeping the area you can avoid being impacted by local cancellation
effects, which could give you a false zero/low reading.
Detecting the Invisible Dance of Radio/Microwaves
Radio waves constantly traveling through our environment can sometimes cancel or
combine with other wave-forms in unexpected ways. Cancelation of waves can create false
low-readings (since in fact the radio waves are still present exerting their biological
influence on you), and waves combining with other waves that happen to be passing
through the same space can create a hotspot, or area of high readings, with measurements
that far exceed the readings in nearby areas but have no apparent source (yet again,
exerting their biological influence on you).
This cancelling and combining of waves is sometimes the result of radio/microwaves from
various technologies overlapping in the same space, or simply due to the nature of waves
themselves. Radio-waves and microwaves can reflect off surfaces like mirrors, refract and
diffract through structures such as building materials, scatter in certain atmospheric
situations, and be absorbed (by our bodies and many other living things).
Your meter will enable you to detect and measure radio waves and microwaves behaving
in all the various ways that they behave according to the laws of physics, yet with different
results depending upon the individual circumstance (for example, waves behave
differently in the presence of a brick fence than they do with a wood fence). That is why
sometimes the readings that your meter is displaying can seem unusual. And most likely,
the readings not unusual at all, but simply seem so due a lack of proper knowledge
regarding wave behavior.
In this brief mention you can see that radio-wave and microwave behavior, in fact all EMF
wave behavior, is a big topic beyond the scope of a meter handbook, however there are
many situations in which this knowledge can give you the important ability to more
accurately interpret the results that your meter is reading. Check out our EMF-Expert.com
