Abstract

본 발명은 가격이 저렴하고, 고속측정이 가능하도록한 부품측정장치에 관한 것이다.The present invention relates to an apparatus for measuring parts at low cost and enabling high-speed measurement.

본 발명은 간결한 구성으로 부품을 측정하는 장치를 구현함으로서 비용문제를 해결하고, 측정속도를 종래에 비하여 상승시킨 부품측정장치를 제공한다.The present invention solves the cost problem by implementing an apparatus for measuring components in a concise configuration, and provides a component measuring apparatus in which the measuring speed is increased as compared with the prior art.

따라서, 본 발명은 저항과 같은 부품을 신속하고 정확하게 측정할 수 있을 뿐 아니라 종래에 사용하던 고가의 LCR미터기를 사용하지 않음으로서 비용을 절감시킨 효과를 가지게 된다.Therefore, the present invention not only can quickly and accurately measure components such as resistance, but also has an effect of reducing costs by not using an expensive LCR meter conventionally used.
