Viscometer.

❏ Spindle Does Not Rotate

✓Makesuretheviscometerispluggedin.

✓Checkthevoltageratingonyourviscometer(115,220V);itmustmatchthewallvoltage.

✓MakesurethemotorisONandthedesiredrpmisselected.

❏ Spindle Wobbles When Rotating or Looks Bent

✓Makesurethespindleistightenedsecurelytotheviscometercoupling.

✓Checkthestraightnessofallotherspindles;replaceifbent.

✓Inspectviscometercouplingandspindlecouplingmatingareasandthreadsfordirt;

cleanthreadsonspindlecouplingwitha3/56left-handtap.

✓Inspectthreadsforwear;ifthethreadsareworn,theunitneedsservice(seeAppendix

✓Checktoseeiftheviscometercouplingappearsbent;ifso,theunitisinneedofservice

(seeAppendixO:WarrantyRepairandService).

❏ Inaccurate Readings

✓Verifyspindle,speedandmodelselection.

✓VerifyspindleselectioniscorrectonDV2T.

✓If%readingsareunder-range(lessthan10%),thedisplaywillash;changespindle

and/or speed.

✓“EEEE”onthedigitaldisplaymeanstheunitisover-range(greaterthan100%);reduce

speedand/orchangespindle.

✓ Verifytestparameters:temperature,container,volume,method.Referto:

✓Performacalibrationcheck;followtheinstructionsinAppendixF.

✓Verifytolerancesarecalculatedcorrectly.

✓Verifythecalibrationcheckprocedureswerefollowedexactly.
