Abstract
In order to permit good test results in the voltage measurement of buried test subjects, an arrangement is provided having a particle beam probe for voltage measurement at a test subject which is spatially separated from a surface by a solid state substance. The solid state substance provides mobile charges disposed in insulated fashion between said test subject and the particle beam probe. A charge separation due to the influence of the test subject potential is produced in the solid state substance so that a potential on the surface of the solid state substance immediately adjacent to the particle beam probe becomes proportional to the potential on the test subject.
