Capacitance

Most capacitance measurements will obtain best results with parallel mode

selected. The majority of capacitors have a very low dissipation factor

(highinternalresistance)comparedtotheimpedanceofthecapacitance.In

these cases, the paralleled internal resistance has negligible impact on the

measurement. There will be some cases where series mode would be used

for a capacitance measurement, or the readings will appear inaccurate.

Series mode is useful when large capacitors have higher dissipation factor

and lower internal resistance.

Inductance

selected.Inseriesmode,accurateQ(qualityfactor)readingscanbe

There will be some cases where parallel mode would be used for an

inductancemeasurement,forexampleironcoreinductorsoperatingat

higher frequencies where hysteresis and eddy currents become signicant.
