For this reason, standard capacitors appear slightly smaller than their actual values. In the LC resonance method, the measurement is performed without error regardless of the reactance of the capacitor. 같은 값을 가진 커패시터에서 유전체(부피)가 다르면 리액턴스가 달라지므로 같은 값을 가진 커패시터라도 ABB LCR Meter에서는 오차가 발생합니다. 이러한 이유로 10nF 이상의 부피가 큰 표준 커패시터는 실제 값보다 약간 작게 나타납니다. ※ ABB LCR Meter (4263B)에서 10 nF 이하 부터 실제 용량 보다 크게 표시하고, 40 pF이하 부터는 다시 적게 표시합니다. 고정도의 LC 공진 방식에서는 커패시터의 리액턴스에 관계없이 측정이 되므로 확도가 좋습니다.       LC Resonance method L and C are calculated more accurately than 0.05% by the reference capacitor during calibration.
