# of Points:Thetestwillcompletewhenthespeciednumberofdatapointshasbeencollected.
DataiscollectedaccordingtotheDataCollectionsetting(seeSectionIII.5).The
rangeofdatapointsis:1–9,999.
# 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.5).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.5).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.5).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.5).
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: IfusingPGFlashtocreateatestprogram,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.7 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.
