<p><P>PROBLEM TO BE SOLVED: To quickly carry out measurements of high accuracy on electrical parameters among prescribed parts in an object to be measured. <P>SOLUTION: A measuring device comprises an I/V conversion part 3 for converting a current I, made to flow between conductor patterns 101 and 101 in a circuit board 100 by the application of a DC signal S1 in current/voltage conversion by a feed-back type; and a control part 5 for measuring an insulating resistor Rs between the conductor patterns 101 and 101, based on an output signal S2 converted by the I/V conversion part 3 and the voltage of the DC signal S1. The I/V conversion part 3 connects a pair of diodes 32a and 32b as the feed-back impedance of the current/voltage conversion. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
