10. easurement Though in some cases series mode would be preferred For instance measuring a large capacitor would require using series mode for optimal reading Otherwise the meter may 19 show the reading results as out of accuracy erroneous Series mode is use because large capacitors often have higher dissipation factor and lower internal resistance Inductance For most inductance measurement selecting series mode is the best This is because in this mode accurate Q quality factor reading can be obtained from reading low Q inductors and ohmic losses are significant Though in some cases parallel mode would be preferred For example iron core inductors operating at higher frequencies where hysteresis and eddy currents become significant would require measurement in parallel mode for optimal results Accuracy Discrepancies In some special cases inaccuracies may occur in the measurement of capacitive inductive and resistive components Capacitance When measuring capacitors it is always most desirable if the dissipation factor is low Electrolytic capacitors inherently have a higher dissipation factor due to their normally high internal leakage characteristics In some cases if the D dissipation factor is excessive measurement accuracy may degrade and even read out of specification Inductance Some inductors are intended to operate at a certain DC bias to achieve a certain inductance value However the LCR meters canno
