Abstract
A static electricity measuring system including a probe, a measuring device, and a calibration device. The probe includes a sensor which detects an electric field and outputs signals representing the detected electric field. The measuring device measures static electricity on the basis of the signals output from the sensor. The calibration device generates a reference electric field. The measuring device is adjusted when the sensor detects the reference electric field produced by the calibration device.
