Fundamentals
Electromagnetic pollution:
This meter is used to indicate electromagnetic
pollution generated artificially. Wherever there is a
voltage or a current, electric (E) and magnetic (H)
fields arise. All types of radio broadcasting and TV
transmitters produce electromagnetic fields, and
they also arise in industry, business and the home,
where they affect us even if our sense organs
perceive nothing.
3.1 Electric field strength (E):
A field vector quantity that represents the force (F)
on an infinitesimal unit positive test charge (q) at a
point divided by that charge. Electric field strength
is expressed in units of volts per meter (mV/m).
This meter measures electric field strength
directly.
3.2 Magnetic field strength (H):
A field vector that is equal to the magnetic flux
density divided by the permeability of the medium.
Magnetic field strength is expressed in units of
amperes per meter (A/m). In far field situations,
one can calculate the magnetic field from the
electric field value. This meter can display the
calculated magnetic field strength.
