Abstract
Use and limitations of Kelvin probe based instruments for surface charge density measurements of dielectric materials are discussed. Three different devices are evaluated: a DC feedback electrostatic voltmeter (ESVM), an AC feedback ESVM and a fieldmeter. Special attention is paid to influence of geometry of the measured object. The effect of viewing angle of the probe, thickness of the sample as well as of stray capacitances are shown theoretically and verified experimentally.
