Chapter 1: Introduction1.1. OverviewThe DE-6000 is a portable, high-performance LCR meter that isfull-featured yet cost effective. It measures in true 4-wire Kelvinmode and rivals the capabilities and options of many of its benchcounterparts.It measures:Ls/Lp-- Series and parallel inductanceCs/Cp-- Series and parallel capacitanceRs/Rp-- Series and parallel resistance (ac)Rdc/Rp -- Series and parallel resistance (dc)ESR/Rp -- Series and parallel equivalent resistanceD-- Dissipation factorQ-- Quality factorΘ-- Phase angleThis LCR meter can transfer data to a PC via a standard, fullyisolated, optical IR-USB interface.It also features a Sortingmode, allowing users to quickly sort components.DE-6000 has automatic LCR selection. This allows the user tomeasure the L/C/R components in Auto LCR mode withouthaving to select the type of measurement.-1-
To accommodate various test requirements, the DE-6000 offersselectable test frequencies: 100 Hz / 120 Hz / 1 kHz / 10 kHz /100 kHz.The unit is powered by a standard 9V battery.For additionalconvenience, it may also use an optional ac adapter(DE-5000-AC).To transfer data to a PC, the unit comes with a built-in IRinterface.IET offers an optional Data Transfer Kit(DE-5000-DTK).This kit includes: IR-USB interface adapter,a USB cable, and a CD with software for the PC.1.2. Introduction to measuring principles1.2.1. What is impedanceImpedance (Z) consists of resistance (real part) and reactance(imaginary part). Series impedance (Zs) can be defined as acombination of series resistance (Rs) and series reactance (Xs). Itcan be represented mathematically as magnitude Z (Rs2 Xs2)at a phase angle Θ.-2-
Zs Rs jXs or Zs ΘRs Zs cosΘXs Zs sinΘXs/Rs tanΘΘ tan-1(Xs/Rs)There are two types of reactance. One is inductive reactance –XL, and the other is capacitive reactance – XC.If Θ 0, the reactance is inductive. If Θ 0, the reactance iscapacitive.The inductive and capacitive reactances (XL and XC) can bedefined as:XL 2πƒLXC 1 (2πƒC)Where:L InductanceC Capacitanceƒ signal frequency)-3-
1.2.2. Measuring impedanceImpedance can be measured in series or in parallel. In parallelmode, impedance can be represented as reciprocal of admittance(Y). The admittance can be defined as Y G jB, where:G ConductanceB SusceptanceSeries impedanceParallel admittanceY 1/Z 1/Rp 1/jXp G jBRs Series resistanceXs Series reactanceCs Series capacitanceLs Series InductanceRp Parallel resistanceXp Parallel reactanceCp Parallel capacitanceLp Parallel inductanceTo understand the ratio of resistance and reactance, it isimportant to consider two factors: quality factor (Q) anddissipation factor (D).Usually Q is used when measuringinductance and D is used when measuring capacitance.defined as the reciprocal of Q.Q 1/D tanΘQ Xs/Rs 2πf Ls/Rs ½πf CsRsQ B/G Rp/ Xp Rp/2πf Lp 2πf CpRp-4-D is

Chapter 2: Operation2.1. How to obtain optimum precisionTo access optimum precision for all L, C, and R measurements,especially at the highest and the lowest ranges, zero the instrumentbefore use (pages 16-18).To secure the specified accuracy, connect the device under test(DUT) to the measuring socket, or use either TL-21 (standardaccessory) or TL-22 (optional accessory).If you are using test leads other than the ones specified above, use4-wire leads and avoid using long lead wires to reduce measurementerrors.2.2. Default settingsWhen the power is turned on, the monitor displays all symbols for 2seconds as shown below.- 12 -
When the meter is powered by the battery, it is in anautomatic-power-off mode.APO is shown on the display.mode, if the unit is inactive for 5 minutes, it shuts itself off.In thisFirst,the buzzer beeps three times to remind the user, then OFF isdisplayed on the monitor as shown below while the unit powersdown.Note that when the unit is powered via an ac adapter, theautomatic-power-off mode is inactive.The default settings for the meter set LCR in auto mode and testfrequency at 1 kHz.The battery condition is continuously displayed.the battery capacity is full.means thatmeans that battery power is lowand the battery needs to be replaced.The LCR meter uses beeps to indicate whether a particular key has afunction in a given mode.single beep.If a functional key is pressed, there is aIf a non-functional key is pressed, there is a dual beep.- 13 -
2.3. Zeroing the meterZeroing the instrument gets better accuracy for impedancemeasurements. The purpose of this procedure is to reduce theparasitic effect of the test fixture.ZM is the total impedance measured on the device under test (DUT)by a test fixture which has some parasitic impedance.ZM (Rs jωLs) ((Go jωCo)-1 ZDUT)ZDUT is the target impedance user wants to measure. It is necessaryto use the zeroing process to cancel the effect of Rs jωLs andGo jωCo.Ex. Operation for open andshort calibration with TL-21Open Cal.Short Cal.- 14 -Ex. Operation for open and shortcalibration with .TL-22Open Cal.Short Cal.
To zero the meter, proceed as follows:1. Make sure the leads are completely disconnected.2. Press the CAL key for 2 seconds.The monitor should display OPEn as shown below.3. Pres the CAL key again.The unit should begin a countdown as it performs OPENcalibration.After the countdown is complete, the monitor should say PASSas shown below. If it says fail, the procedure has to be restarted.- 15 -
4. Connect the test leads for form a short circuit.5. Press the CAL key again.The monitor should display Srt as shown below.6. Press the CAL key one more time.The unit should begin a countdown as it performs SHORTcalibration.After the countdown is complete, the monitor should say PASSas shown below.

2.5. Primary measurements and functions2.5.1. Measuring inductance, capacitance, andresistanceThe DE-6000 starts out in Auto LCR mode which ly – either inductance (L), capacitance (C),or resistance (R).Dc resistance (DCR) can only beselected manually.The value of impedance is shown ndaryshowsthedisplaysecondaryparameter – either quality factor (Q), dissipation factor(D), or phase angle (Θ).The secondary parameter isbased on the L/C/R measurement.When the meter automatically selects impedanceautomatically, it uses the following procedure:If Q 0.2, the meter measures resistance.The parameter on sub-display is Θ.If Q 0.2, the meter measures inductance.The parameter on sub-display is Q.If Q -0.2, the meter measures capacitance.The parameter on sub-display is D.If C 5pF. The parameter on sub-display is Rp.- 19 -
Impedance can also be selected manually by pressing theLCR AUTO key.This is what the process would looklike:The meter starts out in AutoLCR mode.Press LCR AUTO key.The meter enters Auto L mode.The secondary parameter is Q.Press LCR AUTO key.The meter enters Auto CLmode.The secondary parameter is D.Press LCR AUTO key.- 20 -
The meter enters Auto R mode.The secondary parameter isblank. (The meter only displaysΘ automatically in Auto LCRmode.)Press LCR AUTO key.The meter enters DCR mode.The secondary parameter isblank.Press LCR AUTO key.The meter returns to AutoLCR mode.- 21 -
2.5.2. Measuring dissipation, quality, ESR, andphase angleThe DE-6000 can measure dissipation factor (D), qualityfactor (Q), equivalent series resistance (ESR), and phaseangle (Θ).These readings are shown in the secondarydisplay. To select the appropriate measurement, cyclethrough the options using the D/Q/ESR/Θ key.Note: that this function is available in Auto L and AutoC modes only.In other modes the D/Q/ESR/Θ key isdisabled.Example: In Auto C modeThe secondary displayshows D.Press D/Q/ESR/Θkey.The secondary displayshows Q.Press D/Q/ESR/Θkey.- 22 -
The secondary displayshows ESR.Press D/Q/ESR/Θkey.The secondary displayshows Θ.Press D/Q/ESR/Θkey.The secondary displayreturns to D.- 23 -
2.5.3. Sorting componentsThe DE-6000 can sort components into PASS/FAILcategories.Components may be sorted based onresistance, capacitance, or inductance.Note: this function is not available in Auto LCRmode.Before using this function, set the meterto either Auto L mode, Auto C mode, or Auto Rmode.To enter the Sorting mode, proceed as follows:1. Zero the meter.Refer to pages 14-16 for details.2. Press LCR AUTO to cycle through measurementoptions until the desired impedance type isselected.Note: If you select Auto LCR, the sorting functionwill not work.3. Connect one of the items that is going to bemeasured to the test points.4. Press SORTING, then press SETUP.Note: If you press the SORTING key while themeter is reading outside limits (OL) or while thereading is less than 200 counts, the Sorting functionis disabled.- 24 -
5. To adjust the nominal value, proceed as follows:a. Use / keys to adjust the position ofthe decimal point as necessary.PressENTER when finished.b. Use / / / keys to adjust thedigits as necessary.Press ENTERwhen finished.6. To adjust tolerance, use / keys to cyclethrough tolerance options until the desiredtolerance is reached.Press ENTER whenfinished.Available tolerances are: 0.25% 0.5%, 1%, 2%, 5%, 10%, 20%, and -20% 80%.The components may now be sorted.The primarydisplay will show either PASS or FAIL as eachcomponent is measured.The secondary display willshow the value of the measured component, as shown inthe sample below.- 25 -
To make adjustments to the nominal value or tolerance,press SETUP and repeat steps 5 and 6 above.To exit the Sorting mode, press SORTING.2.5.4. Making relative measurementsThe DE-6000 meter can make relative measurements.This option is controlled by the REL% key.When theRelative mode is active, the display shows the Δ symbol.Note: this option is not available in the AutoLCR mode. Nor can it be activated when theparameter being tested is outside of meter limits.The meter uses the following formula to calculaterelative measurements:REL% (DCUR – DREF) / DREF * 100%REL% Percent differenceDCUR Device currently under testDREF Device used as a standard- 26 -
To access the Relative mode proceed as follows:1. Zero the meter. See pages 14-16 for details.2. Select the parameter to be tested.L, C, R, or DCR3. Attach the chosen standard to the test points.4. Press the REL% key.The meter should now display the Δ symbol.5. Remove the standard and attach a DUT to the testpoints.The primary display should show the value of theDUT and the secondary display should show the %difference from the standard.6. Repeat Step 5 for each DUT.Note: The range for the % difference is -99.9% to99.9%.If the DUT falls outside that range, thesecondary display will show OL.7. To exit, press and hold the REL% key for2 seconds.- 27 -
Example: In Capacitance modeDisplay shows themeasurement reading.Ex. 669.3 nFPress REL% keyΔ appears on the screenThe reading on the display isstored as reference value.0.0% is shown on thesecondary display since themeasured value and thereference are the same at thispoint.Remove the standard andattach a different deviceThe new reading is shown onthe primary display.The % difference is shownon the secondary display.Remove the current DUTdevice under test and insertanother.- 28 -
The new reading is shown onthe primary display.The % difference is shownon the secondary display.Press REL% key againΔ flashes on the screen, andthe reference value shows onprimary display.- 29 -
