Abstract : In order to measure absolute values of electric field, an accurate method of calibration of field meters must be obtained. One purpose of calibration is to relate electric output from an inverted field meter to the true field. One method of calibration allows absolute values of electric field from a flush-mounted field meter. A new way of combining the geometry of the field meter mount and atmospheric space charge results in only a slight improvement in measurement error over a former method of calibration involving only time averages. Nevertheless, the experiment points out that atmospheric space charge affects in a complicated manner measurements made with inverted field mills. (Author)
