III. MAKING VISCOSITY MEASUREMENTS
III.1 Quick Start
TheDV2TViscometerusesthesamemethodologyforviscositymeasurementsastheBrookeld
DialReadingViscometersand DVseriesofDigitalViscometers. If you haveexperiencewith
otherBrookeldequipment,thissectionwillgiveyouquickstepsfortakingaviscosityreading.
IfyouhavenotusedaBrookeldViscometerbefore,skipthissectionandgotoSectionIII.2for
a detailed description.
A) Assembleandlevelviscometer(SectionI.4).
B) Turnpoweron.
C) Autozerotheviscometer(SectionII.2).
D) TheDV2TwilldisplaytheCongureViscosityTestScreen.Inthisscreen,select
spindleandspeed.ConrmthatDataCollectionissettoSinglePointandthatEnd
ConditionissettoTime00:00:00.
E) Introducethespindleintothesampleandattachthespindletothecouplingnut.
NOTE: Left-hand thread. IfequippedwithEZ-Lock,usetheappropriateprocedure
toconnectthespindle(seeSectionIII.3).
F) PresstheRunbutton.ThescreenwillchangetotheRunningViscosityTestScreen.
G) Whenyouarereadytorecordthemeasurementresult,presstheStopTestbutton.The
screenwillchangetotheResultsTable.
H) Recordthe%torqueandviscosity.
I) Torunanothertest,pressCongureTest.ToreturntotheHomeScreen,pressthe
Home Icon.
III.2 Preparations for Making Measurements
A) VISCOMETER:TheDV2Tshouldbeturnedon,leveledandautozeroed.Thelevelisadjusted
usingthetwofeetonthebottomofthebaseandconrmedusingthebubblelevelonthefront
ofthehead.Adjustthefeetuntilthebubbleisinsidethecentertarget.Setthelevelpriorto
autozeroandcheckthelevelpriortoeachmeasurement.
The proper level is essential for correct operation of the DV2T.
B) SAMPLE:Theuidtobemeasured(sample)mustbeinacontainer.Thestandardspindles
suppliedwiththeDV2T[LV(1-4),RV(2-7),orHA/HB(2-7)]aredesignedtobeusedwith
a600mLlowformGrifnbeaker(orequivalentcontainerwithadiameterof8.25cm).The
sameappliestotheoptionalRV1,HA/HB1,andVanespindles.Manyotherspindlesystems
aresuppliedfromBrookeldwithspecicsamplechamberssuchastheSmallSampleAdapter,
ULAdapterandThermosel.
Brookeldrecommendsthatyouusetheappropriatecontainerfortheselectedspindle.You
maychoosetouseanalternatecontainerforconvenience,however,thismayhaveaneffecton
themeasuredviscosity.TheDV2Tiscalibratedconsideringthespeciedcontainer.Alternate
containerswillprovideresultsthatarerepeatablebutmaynotbe“true”.
TheLV(1-4)andRV(1-7)aredesignedtobeusedwiththeguardlegattached.Measurements
madewithouttheguardlegwillproviderepeatableresultsbutmaynotprovide“true”results.
When comparing data with others, be sure to specify the sample container and presence/
absence of the guardleg.
