RESISTANCE VALUE MEASURING SYSTEM, INSPECTION SYSTEM OF ELECTRIC CONNECTING POSITION USING IT, AND RESISTANCE VALUE MEASURING METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a resistance value measuring system, capable of measuring a resistance value in a short time in all modes of a measuring resistance. PSOLUTION: This system comprises a bypass resistance RA connected in parallel to a measuring resistance RS and constituting a parallel circuit with the measuring resistance RS, a power source connected to the parallel circuit, a voltage changing means changing a voltage applied to the parallel circuit, an ammeter A measuring a current value of current carried in a predetermined position of the parallel circuit before and after the change of voltage applied to the parallel circuit by the voltage changing means, and a determination means determining a resistance value of the measuring resistance RS based on the current value measured by the ammeter A.
