Improving the accuracy of measurement in component meters
W.A. Evans · 1989
Discusses the development of instruments for establishing the values of practical inductors, capacitors and resistors. The equivalent circuit of a component arrived at from physical considerations can be reduced to one resistive and one reactive component that together produce the same magnitude and phase relationships between current and voltage in a circuit as would the component itself. The equivalent resistive and reactive elements which are measured at the terminals of a complex impedance/admittance measuring system, such as a modern electronic component meter, are discussed. Measurement strategies are proposed that lead to improved accuracy of measurement, particularly of the minor component that often limits the accuracy of measurement of 'loss angle' for example.
