Inductance, capacitance, resistance meters

For the dielectric constant measurement of cellophane EAPap, LCR (inductance, capacitance and resistance) meter (HP4282A) was used, and the frequency ranged from 20 Hz to 10 MHz. EAPap samples were prepared parallel (mechanical), perpendicular (transverse), and 45° to the fiber orientation. Figure 18-8 shows... 

Another option to measure electrical impedance are inductance (L), capacitance (C), and resistance (R) (LCR) meters, typically using various bridge circuits, adjusting variable reference elements until a detector signal becomes nuU. Newer generations also make use of the more general I—V-measurement approach. These are very common... 

The discussions of the first two subsections of Sec. circuit for measurement of the resonant frequency is also useful for obtaining equivalent circuit parameters, such as dynamic capacitance, crystal resistance, and inductance. The measurement of resonant frequency requires a signal generator at the input and a voltmeter or phase meter connected to the output. The resonant frequency can be measured under two distinct circuit conditions at the minimum resonator impedance (fm) or at zero resonator reactance (/)>).
