2. The accuracy of inductance, capacitance and resistance
The quality factor is  10 (dissipation factor  0.1), relative to the impedance accuracy,
where
Inductance = 2πfL
Capacitance = 1/（2 fC）
based on the Figure 2-1 LC and Impedance Conversion Table.
When the quality factor <10 (dissipation factor >0.1), the inductance accuracy times (1+
1/Q) while the capacitance accuracy times (1+D).

Quality Factor < 10, Quality Factor Accuracy times (1 + 1/Q)
Ú The e is the  error spec in Table 2-1.
