ABB (Automatic Balance Bridge) Method

Measured by automatic balance bridge method.(General LCR meter)

※ Capacitors of the same value may have different values if they have different structures or sizes.

 


1409-Y
CH ≒CL ≒ 2.x nF
Actual Capacity  1.005 uF
ABB LCR Meter 1.000 uF


For capacitors greater than 10nF:

In capacitors with the same value, if the dielectric (volume) is different, the reactance is different, so even if the capacitors have the same value, an error occurs in the ABB LCR Meter.

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.


10nF(0.01 uF)보다 큰 커패시터에서:

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.

LC 공진 방식에서는 커패시터의 리액턴스에 관계없이 오차 없이 측정이 됩니다.

 

 



LC
Resonance method


L and C are calculated more accurately than 0.1% by the reference capacitor during calibration.

LC-5000 RF measurement principle (Frequency Oscillator)
※ High accuracy results can be obtained within the measurable range.
 


 

※ It is recommended to use the NP0 as a regular capacitor to make a standard capacitor.
