I. INTRODUCTION
TheBrookeldDV-IIIRheometerserieshasbeentheleadingindustrialrheometersinceitwasrst
introducedin1989.BrookeldhascontinuedtodevelopandimprovetheDV-IIItoprovidethebest
valueinthemarketforbothqualitycontrolandresearchcustomers.TheBrookeldDV3TRheometer
continuesinthistraditionofinnovation,qualityandvalue.Theincorporationofafullcolorgraphical
touchscreendisplayhasallowedforanewandimproveduserinterfacewhichpreservesthesingle
speeddatacollectionmethodswhilemakingalloftheadvancedfeaturesoftheDV3Treadilyavailable.
TheBrookeldDV3TRheometermeasuresuidviscosityatgivenshearrates.Viscosityisameasure
ofauid’sresistancetoow.Youwillndadetaileddescriptionofthescienceofviscosityinthe
Brookeldpublication“More Solutions to Sticky Problems”,acopyofwhichwasincludedwithyour
DV3T.
ThismanualcoverstheDV3TRheometerandtheDV3TExtraRheometer.TheDV3TExtraisaspecial
packagethatincludesseveraloptionalfeaturestomaximizetheutilityoftheDV3T.TheDV3TExtra
includes:BallBearingSuspension(notincludedinLVversions),EZ-Lockspindleconnection,Model
QLabStand,andRheocalcTSoftware.ThesedifferencesaredetailedintheComponentssectionof
themanual.AllreferencestotherheometerinthismanualwillbemadeasDV3T.Alloftheoptional
featuresoftheDV3TExtramaybeaddedindividuallytotheDV3TRheometer.
TheDV3Toffersexceptionalversatilityinmodesofcontrol,allowingchoiceoftraditionalstandalone
operationandautomaticoperationthroughprogramsdownloadedfromthePCorwithcompletecontrol
byPCusingBrookeldRheocalcTSoftware.
• TheDV3TcanbeusedasatraditionalBrookeldrheometerforcollectionofsinglespeed
viscositydatathroughtheeasytousetouchscreen;justselectthespindleandspeedandread
thevaluefromthedisplay. [See Section II: Getting Started]
• TheDV3Tcancollectmultipledatapointsthroughprogramscreateddirectlyonthe
touchscreendisplay.
• TheDV3Tcanmakeadirectmeasurementofyieldstresswhenusingoptionalvanespindles.
• TheBrookeldPGFlashSoftwarecanbeusedtoprogramtheDV3Ttocontrolallaspectsof
thetestanddatacollectionwithouttheneedfortheoperatortomonitortheinstrument;just
starttheprogramandreturntotheprintedtestdata(printerisoptional).[See Section V: PG
Flash Software]
• TheBrookeldRheocalcTSoftwarewillperformallcontrolanddatacollectionfunctions
oftheDV3TfromthePCwhilealsoprovidingaplatformforadvanceddatacollectionand
analysis.
Inanyofthesemodesofcontrol,theDV3Twillprovidethebestinviscositymeasurementandcontrol.
Theprincipalof operation oftheDV3Tisto drive aspindle(which is immersedinthe test uid)
throughacalibratedspring.Theviscousdragoftheuidagainstthespindleismeasuredbythespring
deection.Springdeectionismeasuredwitharotarytransducer.ThemeasurementrangeofaDV3T
(incentipoiseormilliPascal•seconds)isdeterminedbytherotationalspeedofthespindle,thesizeand
shapeofthespindle,thecontainerthespindleisrotatingin,andthefullscaletorqueofthecalibrated
spring.

theappropriateACline.ForCone/PlateModels,besurethatthetoggleswitch,usedto
activatetheelectronicgap,istotheleftposition.(Leftwhenfacingtherheometer.)
TheACinputvoltageandfrequencymustbewithintheappropriaterangeas
shownonthenameplateoftherheometer.(SeeSectionI.2.)
Note: TheDV3Tmustbeearthgroundedtoensureagainstelectronicfailure!!
8. TurnthepowerswitchtotheONpositionandallowtherheometertowarmupfor10
minutesbeforeperformingautozero.
9. ForCone/Platemodels,refertoAppendixA.
10. Ifappropriate,connectUSBcable(DVP-202)toUSBportforconnectionofDV3T
toPCorprinter.

Makesurethattheinstrumentisinaclean,dryworkingenvironment(dust-free,moderate
temperature,lowhumidity,etc.).
Makesuretheinstrumentisonalevelsurface.
Hands/ngersmustbecleanandfreeofsampleresidue.Notdoingsomayresultindeposit
buildupontheupperpartoftheshaftandcauseinterferencebetweentheshaftandthepivot
cup.
Besuretoremovethespindlefromtheinstrumentpriortocleaning.Noteleft-handedthread.
Severeinstrumentdamagemayresultifthespindleiscleanedinplace.
InstrumentandDisplay: Clean with a dry, non-abrasive cloth.  Do not use solvents
or cleaners.  The instrument housing is manufacturedfrom
polycarbonateABS.Cleaninstrumenthousingwithmildsoap
andwater.Do not apply solvent to the instrument!
ImmersedComponents(spindles): Spindlesaremadeofstainlesssteel.Cleanwithanon-
abrasiveclothandsolventappropriateforsamplematerial.
Whencleaning,donotapplyexcessiveforce,whichmayresultinbendingspindles.

II. GETTING STARTED
II.1 Power Up
TheDV3TwillgothroughaPowerUpsequencewhenthepoweristurnedon.TheRheometer
willissueabeep,presentabluescreen,andnallyshowtheDV3TAboutscreenfor5seconds.
TheAboutscreenisshownbelowandincludesseveralcriticalparametersabouttherheometer
including;rheometertorque(LV,RV,HA,HB,orother),rmwareversionnumber,modelnumber
(DV3TLVforexample)andtheserialnumber.
Figure II-1
TheAboutscreencanalsobeaccessedthroughtheSettingsMenu (seeSectionV.1).
TheDV3TRheometerwillautomaticallytransitionfromtheAboutscreentotheAutoZeroscreen.
TIP:WhencontactingBrookeldoryourauthorizedBrookelddealerfortechnicalsupportor
repairservices,pleaserecordtheinformationontheAboutscreenandincludethisdetail
inyouremail.
II.2 AutoZero
TheDV3TRheometermustperformanAutoZeropriortomakingviscositymeasurements.This
processsetsthezeroreadingforthemeasurementsystem.TheAutoZerowillbeperformedevery
timetheinstrumentisturnedon.Additionally,youmayperformanAutoZeroatanytimethrough
theSettingsMenu (seeSectionV.1).
TheAutoZeroscreenwillbepresentedautomatically,aftertheAboutscreen,duringapowerup.

Brookeld Engineering Labs., Inc. Page 14 Manual No. M13-167-A0415
Figure II-2
Theoperatormustensurethattherheometerislevel(seeSectionI.4)andremoveanyattached
spindleorcoupling.WhentheNextbuttonispressed,therheometerwilloperateforapproximately
13seconds.AftertheAutoZeroiscompleteandtheoperatorpressestheNextbutton,therheometer
willtransitiontotheCongureViscosityTestscreen.IftheAutoZerowasperformedfromthe
SettingsMenu,thentherheometerwillreturntotheSettingsMenu.
TIP:DonottouchtherheometerduringtheAutoZeroprocesstoensurethebestzerovalue.
II.3 Status Bar
TheDV3TRheometerwilldisplayastatusbaratthetopofthescreenatalltimes.
