Furthermore, when switching the measurement voltage of the capacitor C X to be measured, it is necessary to remove and attach the connecting lead wire each time, which also reduces work efficiency. Furthermore, since the measurement section 1 and the power supply section 2 are installed individually and independently, the installation area is large, making it difficult to move the inspection device as a whole and requiring protection, which limits the installation location. It also has the disadvantage of being
