In the measurement of dielectric constant and dissipation factor of sheet specimens, the unparallelism of specimen surfaces causes errors in the measurement. This paper describes these errors for the Q meter, reactance variation, varying gap, liquid immersion, and varying gap immersion methods. The errors vary much with the method employed. The errors with the varying gap method are less than those with the Q meter and reactance variation methods, and the errors with the liquid immersion and varying gap immersion methods are much less and usually negligibly small. The results shown in this paper will be a guide in choosing a measuring method and in specifying the required condition of specimen surfaces to be measured by the method.
