CommunicationisestablishedwhentheTestConnectioncommandbuttonispressed.Youmust
pressthisbuttoneverytimetheDV3TRheometerispoweredon.Besurethatthetemperature
controlleristurnedonpriortopressingtheTestConnectionbutton.
TheDefaultTemperaturescreenalsoallowstheusertosetaDefaultTemperature.TheDefault
TemperatureisthesetpointvaluethatwillbeusedbytheDV3Twhenatest(ViscosityTestor
YieldTest)isnotinuse.TosettheDefaultTemperaturerst,enteratemperaturevalueandsecond
checktheDefaultBetweenTestscheckbox.
TIP:UseaDefaultTemperaturewhenthetestprogramincludesachangeintemperatureand
setthevalueequaltothersttemperaturecontrolpointinthetest.Attheconclusion
ofthetest,thecontroldevicewillberesettothersttemperaturesetpointwhichwill
minimizethetimerequiredbetweentests.
TheTemperaturescreenalsoallowsyoutochoosewhichtemperatureprobewillbeusedfordata
collectionandtemperaturecontrol.WhentheDV3Tiscontrollingtemperaturethroughanexternal
device,theremaybetwotemperatureprobesavailablefordatacollection:1)thetemperatureprobe
connected to the DV3T (Probe) and 2) the temperature probe associated with the temperature
controldevice(Controller).PresseitherProbeorControllerintheTemperaturemenu,gurethe
rstoneabove.
Printer Setup:TheDV3TisconguredforusewiththeDymo450printer.Nootherprinterscan
beutilizedwiththerheometer.PrinterSetupallowstheusertochoosefromthree
differentcongurationsforprintout.
LabelSmall:Asmalllabel(1.13inchx3.5inch)thatallowsforprintingoflimited
data for a single data point.  The label stock is available from
Brookeld;partnumberGV-1048.
LabelLarge: A large label (2.31inch x 4.0inch) that allows for printing of a
completesetofparametersforasingledatapoint.Thelabelstock
isavailablefromBrookeld;partnumberGV-1049.
Receipt: Acontinuousrollofpaperthatallowsforprintingofmultipledata
points.ThepaperstockisavailablefromBrookeld;partnumber
GV-1047.
ThePrinter Setupis selectedby touching thedesired conguration,which will
resultinabluecircletoappeartotheleftoftheitem.TheOKcommandkeymust
beselectedtoconrmthesetting.
AutoZero: AutoZeroisanoperationperformedby the DV3TRheometerautomaticallyduring
thepowerupsequence.Thisoperationsetstheinstrumenttransducertoacorrectzero
value.Thezerovalueshouldnotshiftovertime,however,iftheuserdeterminesthat
thezeroisnotcorrect,youcanforceanAutoZerotobeperformedwithoutpowering
downtherheometer.WhentheAutoZerofunctionisselected,theDV3Tisimmediately
setstoAutoZeromodeandtheuserispresentedwiththeAutoZeroscreen(FigureII-2).
Uponcompletion,theuserwillbereturnedtotheDeviceSetupmenu.
Oscillation Check: TheOscillationCheckisacheckoftheperformanceofthelowerbearingofthe
DV3TRheometer.ThislowerbearingiseitherPointandJewelorBallBearing.
Correctperformanceofthelowerbearingisessentialforproperoperationofthe
rheometer.Afailedlowerbearingwillnormallycauseviscositymeasurements
tobelowerthanexpected.
