# of Revolutions:
Thetestwillcompletewhenthespeciednumberofrevolutionsofthespindle
hasoccurred.DataiscollectedaccordingtotheDataCollectionsetting(see
SectionIII.6).Therangefornumberofrevolutionsis:1–9,999.
Torque:
ThetestwillcompletewhenthespeciedTorquevalueismeasured.Data
iscollectedaccordingtotheDataCollectionsetting(seeSectionIII.6).The
rangeofvaluesforthemeasuredTorqueis:-10.0–100.0.
Viscosity:
ThetestwillcompletewhenthespeciedViscosityvalueismeasured.Data
iscollectedaccordingtotheDataCollectionsetting(seeSectionIII.6).The
rangeofmeasuredViscosityis0–10,000,000,000cP.
Note:TheViscosityEndConditionshouldbeselectedinconsiderationofthe
Rangeprovidedbythespindleandspeedselected.ChecktheRange
valuebyselectingSpindleinCongureViscosityTest.Ifyouchoose
aViscosityEndConditiongreaterthantheRangeofthespindleand
speedsettings,thenthevalueshownintheEndConditioneldwill
beEEEE.Inthiscase,theendconditionwillneverbeachieved.
Temperature:
ThetestwillcompletewhenthespeciedTemperaturevalueismeasured
towithintheindicatedTolerance.TheTolerancespecieshowclosethe
measuredtemperatureshouldbetothespeciedtemperaturevaluetoconsider
thetargetreached.Temperatureismeasuredthroughtheuseofaconnected
Brookeldtemperatureprobe(DVP-94Y,CPA-44ZPYcup,SC4-XXRPY
chamber).DataiscollectedaccordingtotheDataCollectionsetting(see
SectionIII.6).
Temperature:-100–300C
Tolerance:0.0–9.9C
TIP: Asmalltolerancevaluewillrequireamuchlongertimetoreachthe
EndCondition.
TIP: Consider using alargerTolerancevalue forthe End Conditionand
thenuseasecondstepforthermalequilibrium(EndConditionTime).
Thistwostepmethodcanreducethevariabilityintesttimecausedby
variationsintemperaturesensors.
III.9 Additional Test Parameters
TheCongureViscosityTestscreenincludesaMore/LessBar.Whenpressed,theMoreBarwill
presentseveraladditionalTestParametersincluding:QCLimits,Instructions,Reports,andDensity.
TheseparametersarealwaysavailableandactiveregardlessofthepositionoftheMore/LessBar.
QC Limits:Selectanacceptablerangeformeasurementresults.Therangemaybedened
byViscosity,Torque,Time,Temperature,orShearStress.Thepossiblerangefor
ViscosityandShearStresswillbedenedbythespindleandspeedselected.QC
Limitsareavisualandaudiblesignaltotheoperatorduringthetest.Thedataset
doesnotincludeanindicationofQCLimitsviolation.
AviolationoftheQCLimitsduringthetestwillbeindicatedbyaashingyellowboxaroundthe
displayforthespeciedparameter.NotethatTimedoesnothaveadedicateddisplay.Aviolation
willalsoresultinanaudiblebeepandaonetimewarningmessage(seeFigureIII-11).Datawill
continuetobecollectedwhilethewarningmessageisdisplayed.
