CAUTION: When using the1/2pintcan,donotlowerthespindledirectlyintothe
container.The narrowdiameterof thecanrequires thespindleto be
introducedatanangle.Tiltthe1/2pintcanwhileloweringtheviscometer.
 8) Thespindlewillbegintorotateoncethehandleiswithin1/2inchofthelowestposition.
 9) Wait5secondsforthedisplayreadingtostabilize.Adisplayof"----"indicatesanover-range
condition.Ifaprinterisbeingused,thesedasheswillprintinplaceofdata(Figure7).
 10) Movethe Hold Reading Switch to the down position
to"Hold"thedisplay.Ifaprinterisconnected,astring
ofdatawillprintassoonastheHoldreadingswitchis
movedtothedownposition(Figure7).Thedisplayunit
selectorswitchmaybeusedtochangethedisplay.
 11) Raisethehandletothetopposition.Thisstopsthespindle
fromrotating.
Note:Whenusing1/2pintcans,youmustliftthecanandthentiltslightlytoremovethe
spindle.
 12) Loosenthethumbscrewandremovespindleforcleaning.
Note:Donotremovethethumbscrew.Ifdropped,itmayfallintothesample.
II.3 Troubleshooting
 IftheoperatinghandleisintheDOWNpositionandthedisplaylocksupand/orthespindledoes
notrotatethefollowingshouldbechecked:
 • BesuretheHOLDswitchisintheUPposition.IftheholdswitchwasintheDOWNposition
priortoengagingtheoperatinghandle,dashes(——)orthepreviousreadingmayappearin
thedisplay.
 • TheKU-2requiresashutdown(poweroff)periodofatleast30secondsbeforeitcanbeoperated
properly.Iftheunithadpreviouslybeenturnedoffandimmediatelyturnedbackon(without
a30secondshutdownperiod)boththedisplayandrotationmaytemporarilylockup.
 Ifyouexperiencetheseproblems,simplyraisetheoperatinghandle,turntheunitoffandwaita
minimumof30secondsbeforeturningthepowerbackon.
