    4. MEASURING PROCEDURE E-field sensors The tester meter that measures and displays EMF in Gauss and Tesla units with a frequency bandwidth of 30 to 300Hz. The 3 axis sensor allows for three component (xyz) measurement coverage. The tester Meter is specifically designed to determine the magnitude of electromagnetic fields generated by power lines, televisions, computers electric appliances and many other similar devices.

    3. Pay special attention to measuring the neighboring vicinity for possible radiation sources. Apart from active sources, those components connected to a source may also act as radiators. For example, the cables used in diathermy equipment may also radiate electromagnetic energy. Note that metallic objects within the field may locally concentrate or amplify the field from a distant source.
