Reed Instruments R5001 - Primary Impedance and Secondary Parameter Testing; Choosing Series or Parallel Measurement Mode

Primary Impedance with Secondary Parameter Test
The default test mode for this meter is Auto-LCR Mode, which checks the
typeofimpedanceandautomaticallyentersL/C/RMode.Thesecondary
parameterwillfollowtheL/C/Rmeasurement,meaningthat(L+Q),(C+D)*,
(R+θ)** are combined in one group respectively.
1. Press the FUNC button to switch from Auto-LCR Mode to Auto-Lp
Mode, Auto-Cp Mode, Auto-Rp Mode, and DCR Mode.
Note: When Auto-Lp or Auto-Cp Mode is selected, the impedance
measurement is auto ranging. The primary LCD display will show the
inductanceorcapacitanceofDUT(deviceundertest);whilethesecondary
LCD display will show the quality or dissipation factor.
2. Press the buttontodisplaytheD/Q/θ/ESRvalue.WhenAuto-R
(ACRmode)orDCRmodeisselectedthesecondaryparameter
is omitted.
* When Auto-LCR mode is active,
the secondary parameter will
show the equivalent resistance in
parallelmode(Rp)toreplacethe
D factor if the C measured value
oftheDUTislessthan5pF.
** Auto-LCR mode only. During
Auto-R Mode or DCR Mode,
the secondary parameter is
not available.
Series or Parallel Functions
Just as test frequency can greatly affect measurement results, selecting
between series or parallel measurement mode can also affect the accuracy
of the meter, especially for capacitive and inductive components. This
section provides some recommendations and suggestions to consider.
