III.2 Preparations for Making Measurements

 A) VISCOMETER:TheDV2Tshouldbeturnedon,leveledandautozeroed.Thelevelis

adjustedusingthetwofeetonthebottomofthebaseandconrmedusingthebubble

levelonthefrontofthehead.Adjustthefeetuntilthebubbleisinsidethecentertarget.

Setthelevelpriortoautozeroandcheckthelevelpriortoeachmeasurement.

The proper level is essential for correct operation of the DV2T.

 B) SAMPLE:Theuidtobemeasured(sample)mustbeinacontainer.Thestandard

spindlessuppliedwiththeDV2T[LV(1-4),RV(2-7),orHA/HB(2-7)]aredesignedtobe

8.25cm).ThesameappliestotheoptionalRV1,HA/HB1,andVanespindles.Many

otherspindlesystemsaresuppliedfromBrookeldwithspecicsamplechamberssuch

astheSmallSampleAdapter,ULAdapterandThermosel.

  Brookeldrecommendsthatyouusetheappropriatecontainerfortheselectedspindle.

When comparing data with others, be sure to specify the sample container and

presence/absence of the guardleg.
