Brookfield DV2T - III.4 Data Averaging and Analysis

Brookeld Engineering Labs., Inc. Page 36 Manual No. M13-167
Eachdatapointincludes:Viscosity,Torque,Speed,Temperature,Time,ShearStress
(SS),ShearRate(SR),Density,andAccuracy.
Post Test Averaging : Average and Standard Deviation are calculated for measured and calculated
parametersincluding:Viscosity,Torque,ShearStress,andTemperature.
PostTestAveragingiscalculatedregardlessoftheDataCollectionsetting.
IfDataCollectionwassettoMultipointAveraging,thenthePostTest
Averagingwillcalculateanaverageoftheaverageddata.
WhenusingmultiplestepprogramsgeneratedthroughPGFlashsoftware,
theteststeputilizedforPostTestAveragingisspeciedintheReport

III.10 Data Averaging
The DV2T Viscometer offers two techniques to average data, Live Averaging and Post Test
Averaging.Dataaveragingcanbeusefulwhenmeasuringsampleswithentrainedairorsuspended
particlesthatcasesomevariationinmeasurementresults.Dataaveragingmaynotbeusefulwhen
changesinmeasurementresultsarecausedbytherheologicalpropertiesofthetestsamplesuch
