When the input frequency is swept within 100 Hz to 3 kHz, the resonant frequency is defined as the frequency where the impedance shows the minimum value, and this impedance shall be the resonant impedance. Static Capacitance The electrostatic capacitance shall be measured at 120 Hz by using LCR meter HP4194A(H.P.) or equivalent. This part shall be clamped in the same way as the measurement of resonant frequency and resonant impedance as mentioned above. cuidevices.com
