Specifications that should be provided to characterize instrumentation used to measure the steady state root mean square (rms) value of magnetic and electric fields with sinusoidal frequency content in the range 10 Hz to 3 kHz are identified. The instrumentation, recommended calibration methods, and sources of measurement uncertainty are also described.

This recommended practice identifies specifications that should be provided to characterize instrumentation used to measure the steady state Root mean square (rms) values of magnetic and electric fields with sinusoidal frequency content in the range 10 Hz to 3 kHz in residential and occupational settings as well as in transportation systems. The dynamic ranges of interest are 0.01 MicroT (0.1 mG) to 10 mT (100 G) and 1 V/m to 30 kV/m for magnetic and electric fields, respectively. In addition, this recommended practice -- Defines terminology. --Describes general characteristics of fields. --Surveys operational principles of instrumentation. -- Indicates meth...

The interest in characterizing quasi-static magnetic and electric fields in a number of environments has led to the development and marketing of many field meters with a range of specifications. Sources of quasi-static fields include devices that operate at power frequencies and produce power frequency and power frequency harmonic fields, as well as devices that produce fields that are independent of the power frequency. Because of differences in the characteristics of the fields from sources in the various environments, for example, frequency content, polarization, nonuniformity, and magnitude, the instrumentation requirements for measurements in the variou...
