<P>PROBLEM TO BE SOLVED: To enable contact check, charging check, and insulation resistance check to be positively conducted, even with an extremely simple structure. <P>SOLUTION: After charging a capacitor C at a specified voltage at a charging step, in an inspection step, with a predetermined DC voltage applied to the capacitor C by a DC power source E via a pair of probes P, the current value (leak current) of the current running through the capacitor C is measured using an ammeter 11 to inspect whether the capacitor is good or bad. In this inspection, a voltmeter 12 is connected between the pair of probes P and a switch 13 is provided on the DC power source E, and then by turning the switch 13 off, contact check and charging check are conducted via the voltage measurement value measured by the voltmeter 12. If both checks produce good results, insulation resistance check is conducted by turning on the switch 13. <P>COPYRIGHT: (C)2013,JPO&INPIT |
