Appendix1 Measurement Parameters and Calculation Formula
A2
From the voltage V which is applied between the terminals of the sample under test, the current I which
flows through the test sample at this time, the phase angle
 between this voltage V and this current I,
and the angular velocity
 which corresponds to the measurement frequency.
*  : phase angle of admittance Y (  = -  )
Ls, Rs, Cs: The measured values of L, C, and R in series equivalent circuit mode.
Lp, Rp, Cp: The measured values of L, C, and R in parallel equivalent circuit mode.
The phase angle  is shown based on the impedance Z. When measuring based on the
admittance
Y, the sign of the phase angle  must be reversed.
