
Thedimensionsofthebalanceweightsaredetected,on
thebasisofrealdata,orratheronmeasurementstaken
directlybytheGaugesiftheautomaticEasyAlufunction
isused.Ifthedataisenteredmanuallythesefiguresare
calculatedonthebasisofnominalvaluesbyaddingor
subtractingtheaveragecorrectionvalues.

5.6.1CalibrationGauge

TheinternalCalibrationGaugefordistanceand
diameterisusedtoenterthedistancebetweenthe
machineandtheleftcorrectionplane,aswellasthe
nominalrimdiameter/correctiondiameter.Theinternal
CalibrationGaugeallowstheeffectivecorrectionplanes
anddiametersoftheadhesiveweightsfixedtothebead
seatsandhiddenweightstobecalculatedexactly.

Application:ExtractandresttheGaugeHeadontherim
andkeepitinpositionuntilanaudiblesignalisheard.

MovetheGaugetotheidleposition.Whenthe
measurementshavebeencompletedandtheidle
positionisreached,therimdimensionsareshownon
theDisplay.Aselectionofweightpositions(Alutype)is
alsoshown.IftheGaugedoesn’tfunctioncorrectlyorif
thecorrectionpositionsonthewheelonthemachine
areoutsidethecalibrationreadingfield,itisstill
possibletosetthedimensionsfromthemenuand
proceedinmanualmode.
