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
