III.8 Running a Test
AviscositytestisstartedbypressingtheRunbuttonontheCongureViscosityTestscreen.When
Runispressed,thedisplaywillchangetotheRunningViscosityTestscreen(seeFigureIII-9).

TheRunningViscosityTestscreenprovidesinformationonthecurrentmeasurementincluding:
Torque,Viscosity,ShearStress,ShearRate,TemperatureandSpeed.
TorqueisthedeectionoftheViscometertorquesensor.Itisdescribedasapercent(%)andhas
arangeof0–100%.TheDV2Twillprovidemeasurementresultswithinthestatedaccuracy
providedtheTorquereadingisbetween10and100%.IftheTorquereadingfallsbelow10%the
labelsinthedataeldswillashtoindicateanerrorcondition.Brookelddoesnotrecommend
thatdatabecollectedbelow10%Torque;however,datacollectionisnotrestricted.
TIP: TorqueontheDV2TisequivalenttothedialreadingfromtheBrookeldDialReading
Viscometerorthe % readingfromBrookeldDigitalViscometers(DV-E, DV-I,
DV-II,DV-III).
ViscosityiscalculatedfromthemeasuredTorquebasedontheselectedspindleandspeedof
rotation.TheunitsofviscosityaredenedintheGlobalSettingssectionoftheSettingsMenu
.IftheTorquereadingfallsbelow10%,thelabelsinthedataeldswillashtoindicate
an error condition.
Shear StressiscalculatedfromthemeasuredTorquebasedontheselectedspindle.Theunitsof
shearstressaredenedintheGlobalSettingssectionoftheSettingsMenu .IftheTorque
readingfallsbelow10%,thelabelsinthedataeldswillashtoindicateanerrorcondition.
TIP:ShearStresswillbedisplayedaszeroforspindlesthatdonothaveSRCvalues.
Shear Rateiscalculatedfromtheselectedspeedbasedontheselectedspindle.
TIP:ShearRatewillbedisplayedaszeroforspindlesthatdonothaveSRCvalues.
