Method B: Without Using a Survey Rover
Beforeyoubegin,ensurethatallequipmentandmeasurementsareusingthe
sameunitsofmeasure(i.e.Meters,SurveyFeet,etc.).
RecordMeasurements:
1. Positionthemachineonaflatsurface,andplaceahubinaflatopen
area.
2. Using3D‐MCasareference(inalocalizedproject),taptheElevation
ControlKey,theleftGPSinfo...button,andthentapthePositiontab.
3. Positionthemachinedirectlynorth.Bothbucketedgeswill havethe
sameNorthingvalue(Figure72onpage52).
4. Retracttheelementsandthebucketsothatitiscurledinnear
machine,andplaceabucketcorneronthehub.
5. RecordtheEastingvalueofthebucketcorner(e.g.Easting
N
=520.35).
6. Raiseonlytheboom,movethemachineforwardbeyondthehub,and
rotatethemachinebody180°tofacedirectlysouth.
7. Placethebucketcornerchoseninstep4onthehubandrecordthe
Eastingvalue(Easting
S
=520.41).
CalculateAdjustments:
1. Calculatetheadjustmentneededin3D‐MCfortheMainAntenna‐to‐
BoomCenterlinelengthusingthefollowingequation:
Adjustment=[(Easting
S
‐Easting
N
)/2](seeTable9).
2. Adjustthevaluein3D‐MCfortheMainAntenna‐to‐BoomCenterline
measurementbythecalculatedamount.Donotphysicallymovethe
antenna.
• Apositiveadjustmentshouldbeaddedtothe3D‐MCvalues(the
distanceawayfromthecenterlineincreases).
• Anegativeadjustmentshouldbesubtractedfromthe3D‐MCvalues(thedistanceawayfromthe
centerlinedecreases).
