Page 6: Fundamentals
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. -
Page 7: Power Density (S)
3.3 Power density (S): Power per unit area normal (perpendicular) to the direction of propagation, usually expressed in units of Watts per square meter (W/m ) or, for convenience, units such as mill Watts per square centimeter (mW/cm 3.4 The characteristic of electromagnetic fields(S): Electromagnetic fields propagate as waves and travel at the speed of light (C). -
Page 8: Application
Application Quite often routine, maintenance and service work has to be done in areas where active electromagnetic fields are present, e.g. in broadcasting stations, etc. Additionally, other employees may be exposed to electromagnetic radiation. In such cases, it is essential that personnel be not exposed to dangerous levels of electromagnetic radiation, such as: ... -
Page 9: Electromagnetic Safety Reference Standard
electromagnetic safety reference standard 1W/m² =0.1mW/Cm² =100uW/Cm² Features The meter is a broadband device for monitoring high- frequency radiation in the range from 50MHz to 3.5GHz The non-directional electric field antenna and high sensitivity also allow measurements of electric field strength in TEM cells and absorber rooms. - Page 10 The meter can be set to display the instantaneous value, the maximum value measured or the average value. Non-directional (isotropic) measurement with three-axis measurement sensor. High dynamic range due to three- channel digital results processing. Configurable alarm threshold and memory function.
