INTRODUCTION
TheKAM®WeightScaleisdesignedforintegrationwiththeKAM®CSS Complete Sampling System and is used
toverifysamplevolumeinKAM®SRSampleReceiversperAPIChapter8.2,ASTM4177andISO3171.Weight
Scale units (generally 2) are placed inside a KAM®SRHSampleReceiverHousing,andtheKAM®SR Sample
ReceiversareplacedontopoftheWeightScaleplatforms.
EachWeightScaleunitcommunicateswiththeKAMSCSamplerControllervia4-20mA.The4-20mAsignal
directlycorrelatestothecurrentweightoftheSampleReceiveranditsvolumetricequivalent.Inthisway,op-
eratorscanremotelymonitorforaccumulatedsamplevolume,andautomaticallyswitchtoasecondSample
Receiverforcontinuedsamplecollectiononcetherstreceiverisfull.

1.PlaceWeightScale(s)inSampleReceiverHousing
andadjustfeetbyscrewingtheminorout(Fig.3-2)
toensurethatthescaleiscompletestableanddoes
notrock.
2.MountWeightScaleController(s)within6'–8'(2–
2.4M)ofhousing.
3.ConnecttheScaleandtheScaleControllerwith
thesupplied10'wireusingquickconnects.
WARNING:TheKAMWeightScalehasmechanical
stopstopreventdamagefromoverweightreceivers.
HOWEVER,placingreceiversabovethemaximum
weightorslammingreceiversdownontoscalewill
resultindamagetothescale.
1.RemovecoverfromWeightScaleControllerbyrst
removingsetscrewonthebottomofcover(seeFig.
3.3)andthenturningcovercounterclockwise.
2.RemoveLCDdisplayplatebyrstremovingthe(3)
