Torque Reduction

Torque Reductionispercentagechangeintorquevaluebetweensuccessivedatapoints.Thatis,the

materialyieldsorbeginstobreakdownand,asaresult,themeasuredincrementaltorquebeginsto

decrease.Avalueof100%forthisparametercausesthetesttostopassoonastherearenotorque

increasesduringabasetimeincrement.Someusersmaywishtoseeadropintorqueafterthe

yieldpoint.Settingthisparametertovaluesgreaterthan100%allowsdatatobecollectedafterthe

yieldpointbytheEZ-Yield

softwaresothedecreaseintorquemaybemoreeasilyvisualized.

However,thiswillalsoaffectthecalculatedyieldstressvalue.

Yield Limits

ThesestressvaluescanbeusedasaQualityControltool.Iftheresultingyieldstressfromatest

fallsoutsidetheselimits,anappropriatemessageisdisplayedandprintedwiththeresults.Entering

zero(0)forboththeseparametersdisablesthisQCfeature.

Instructions

Recordspecicinstructionstotheoperator.Thisinformationwillbepresentedimmediately

whentheprogramisRun(seeFigureIV-6).Theoperatorisrequiredtoacknowledgethemessage

beforetheprogramwillcontinue.

TIP:Iftheoperatorselects“Donotshowthismessageagain”withintheInstructionsmessage

box,thenInstructionswillnolongerbedisplayedforanytest.Thisconditioncanbe

resettoallowInstructionstobedisplayedintheDisplaysectionofUserSettings

TIP:Instructionscanbeviewedduringthetestbyselectinginstructions(more/lessbar)in

theViewTestscreen.

Save Path

Denethememorylocation(internalorUSBFlashDrive)wheretheTestResultswillbesaved.

TIP:Selectingadatapathcanhelptoorganizedatastorageintheinternalmemoryofthe

DV3T.Bypreselectingthedatapath,operatorsaredirectedtoputthedatafromspecic

testsintospecicareas.

TIP:IfyouselectadatapaththatincludesaUSBFlashDrivelocationandtheFlashDrive

hasbeenremoved,anerrormessagewillbedisplayed.
