Series/parallel Equivalent Mode
D.E.V.I.C.E. is an encyclopedia of terms used by manufacturers of test and measurement equipment. T&M Atlantic created this service to better explain the functionality of instruments it offers, and to highlight the latest developments in the world of measurement equipment. We are using such tools as animation to bring words and pictures to life and to create not just an understanding but also an appreciation for technology that goes into the design of every instrument.

For the presence of non-ideality and distributed parameters of components, actual components are usually equivalent to combined network of ideal components. In general, there are two simple equivalent models used in LCR meters, which are series model and parallel model:
Appropriate equivalent modes could help to gain better measurement results. Generally, Series mode is better for components with low impedance (below 100Ω), while parallel mode is for components with high impedance (over 10kΩ). For the components with the impedance between the two limits, equivalent mode has little effect on the testing result.
In modern RLC measurers equivalent mode can be selected automatically. Besides series mode is selected for components with low impedance (below 10kΩ), it’s shown on a device display (e.g. Ls/Cs/Rs). For those components that have high impedance (over 10kΩ) there should be parallel mode selected and the display shows, for example, Lp/Cp/Rp. For the majority of devices equivalent mode can be selected manually.
