ABSTRACT:
An improved apparatus is disclosed for measuring the surface insulation characteristics of coatings on magnetic materials. This apparatus comprises an insulative button block having a plurality of protruding contact buttons stationarily mounted therein, with each contact button provided with a substantially flat contact surface, and with all contact surfaces lying substantially in the same plane. The apparatus further includes a press for urging the contact surfaces against the coated surface of the magnetic material, the electric circuitry necessary to apply a predetermined voltage potential between the contact surfaces and the magnetic material, and an ammeter to measure the current flow through the coating.
