Electric field meter, calibrations

Static Voltmeter These instruments are calibrated to indicate the potential (V) on an ungrounded conductor and usually have more than one calibrated meter/surface spacing. They can be used, for example, to indicate the potential on ungrounded persons or equipment. A meter that indicates in volts or kilovolts is not an electric field meter. 

Electric Field Meter These meters are calibrated to indicate the polarity and magnitude of the electric field (V/m) at the sensor. They should have only one calibrated meter/surface spacing and should be... 

Power monitoring diodes were used to set the rf power so the rf electric field did not vary as a function of frequency. The diodes were calibrated using a Hewlett Packard 432A Power Meter with a 8478B thermistor power sensor and calibrated attenuators. The power measurement was used in conjunction with slotted line studies of the rf interaction regions to determine the rf electric field at each frequency.
