III.3 Programming

TheDV3TRheometerprovidesapowerfulprogrammingcapabilityfordatacollection.Theinterface

inCongureViscosityTestallowsforcontrolofallinstrumentparametersincludingSpindle,Speed,

Temperature(optional),EndCondition,DataCollection,Instructions,Reports,Density,andQCLimits

(describedinthenextsectionsofthischapter).Anycollectionoftheseparametersisconsidereda

TestStep.TheDV3Tallowsyoutocreatemultiplestepstobetterevaluateyoursamplematerial.

SeveralparametersareonlyactiveintherststepincludingSpindleandInstructions.

MultiplestepsinaTestcanbeusefultoevaluatetherheologyofasampleortosimplyaidindata

collection.AmultistepTestthathasachangeinspeedineachstepcanshowNewtonianornon

Newtonianowbehavior.ArststepwithNoDatacanbeusefulwhenpreshearingisrequired.A

stepwithNoDatacanbeusefulwhenatemperaturechangeiseffectedandsometimeisrequired

forthermalequilibrium.
