ABSTRACT:
Frictional electrostatic voltage measuring equipment for measuring the frictional electrostatic voltage characteristics and the discharge characteristics of a sheet-form sample such as textile and film, the sheet-form sample being held by a sample plate in a stretched condition. A sample table for holding detachably the sample plate is provided reciprocably on a body base; a rubbing unit comprising a rubbing pad and its driving unit, a pedestal and an electrostatic voltage sensor are provided. The sample held by the sample plate on the sample table is rubbed by the rubbing pad with the sample supported by the pedestal from its back, the sample table being allowed to move to a measuring position after the completion of rubbing. At this point, the electrostatic voltage of the sample is detected by the electrostatic voltage sensor, and the detecting signal is processed by a data processor.
