Brookeld Engineering Labs., Inc. Page 28 Manual No. M13-167-A0415
TwomultistepTestsareshownbelow.Thersttestshowsathreesteptestwhereeachstephasa
differentspeedwithasingledatapointcollection.Theresultswillincludethreeviscositypoints,
oneforeachspeed.Thesecondtestshowsatwosteptestwheretherststepisapreshearstep.
Thepreshearisconductedat200rpmforoneminuteandnodataiscollected.Thesecondstep
generatesasingledatapoint.

III.4 Selecting a Spindle/Speed
TheDV3Thasthecapabilityofmeasuringviscosityoveranextremelywiderange.Forexample,
theDV3TRVcanmeasureuidswithintherangeof100-40,000,000cP.Thisrangeisachieved
throughtheuseofseveralspindlesovermanyspeeds.SeeAppendixBfordetails.
