7.8.3 |Z|, |Y|, L, C, R, X, G, B and Rdc Accuracy
For high impedance (>10kOhm) value:
Ae[%] = ((A + 0.0000001*Zx) * Kv * Kt)
For low impedance (<100Ohm) value
Ae[%] = ((A + 0.1/Zx) * Kv * Kt)
Where,
A= Accuracy from accuracy chart
Zx= Measured value of unknown component
Kv= Test voltage factor (Refer to Table A)
Kt= Temperature factor (Refer to Table B)
L, C, X, and B accuracy apply when D < 0.1
R, G accuracy apply when Qx < 0.1
When D ≧ 0.1, multiply Ae by √ 1 + D² for L, C, X and B accuracies.
When Q≧ 0.1, multiply Ae by √1 + Q² for R, and B accuracies
Rdc Accuracy= Refer to Z accuracy at 20Hz
7.8.4 D Accuracy
De = (Ae / 100)
If D > 0.1, multiply D accuracy by (1+D²)
7.8.5 Q Accuracy
Qe = ((Qx²*De) / (1Qx*De))
Where, Qx is the measured Q value,
De is the relative D accuracy.
Accuracy applies when Qx * De < 1
