Poor connection of the high voltage test wire to the DUT may lead to a lower measurement current and invalid qualified product results in the voltage test. Once this function is enabled (with non-zero settings) your machine will measure the DUT's capacitance with low voltage for about 200ms before the high voltage test begins.
