The impact of electric charge, gathered in a tested specimen before a testing voltage has been applied to it, on the results of measurement of its volume resistivity is considered. It was shown that the specimen should be discharged before the measurement. The alternating polarity test method, employed by Keithley's 6517 Hi-R Test program, does not eliminate completely the effect of electric charge. A modification of the method, enabling the elimination from the measurement results of the electric charge which could be the reason of de-electrization current flow (background current) and resorption current, has been proposed.
