APPARATUS FOR INVESTIGATING STATIC ELECTRIC FIELD Russian patent published in 2014 - IPC G09B23/18 

FIELD: physics.

SUBSTANCE: rectangular sheet of electrically conductive paper (ECP) with a recess with the shape of a detachable conductor is placed on a rectangular board. Conducting lines are placed in parallel at opposite sides of the rectangular sheet of ECP. A slider of a movable line is provided with a vertical opening for inserting a probe and a mark for reading the position of the probe on the movable line. The probe is inserted into the vertical opening and touches the rectangular sheet of ECP with its lower end. A rail is attached by one end to the slider perpendicular to the movable line. An extractor ring made of dielectric material with a marking is placed on a removable conductor and placed on the rectangular sheet of ECP. Terminals of a multichannel analogue-to-digital converter (ADC) are connected to inputs of a personal computer, and the second inputs of each channel are connected to the negative terminal of a direct current source. Potentiometers and probes are connected to ADC channels.

EFFECT: automation of laboratory work and faster analysis.
