FIELD: electric engineering. ^ SUBSTANCE: device contains a toroid, mounted perpendicularly to table covered by foil, while its first half is above the table, and other half - below it. Winding of toroid is connected to output clamps of sound frequency generator, double probe is mounted in points of electric field on foil being studied, its clamps are connected to inputs of voltmeter, moving bushing is pinned on toroid and abuts during movement against aforementioned table with foil. Moving platform is held on support and pinned onto the rod. Rotation axis passes through moving platform. Handle is fastened immovably to other end of rotation axis. Arrow is mounted on double probe on same line with needles of probe. Spring is supported by handle and moveable platform. Device is provided with device for measuring difference of phases, first input of which is connected to outputs of binary probe, and additional double probe, mounted immovably in point of electric field on foil being studied, while its clamps are connected to second input of device for measuring phase difference. ^ EFFECT: extended functional capabilities. ^ 5 dwg
