Table 26
Calibration Summary
Item Fields (from the left) Description
Arm Measurements- Boom
- Stick
- Bucket Width (meters) Data calculated by the system, for the width, length and height of the boom, stick and bucket.- Width = perpendicular to the machine
- Length = pin to pin along centerline
- Height = pin to ground
The system uses width and height to draw the machine icon on the display, and uses length for important calculations.
Length (meters)
Height (meters)
Body Measurements- Master GNSS
- Slave GNSS
- COR Offset
- Machine Offset from boom pin (East) The offset of the GNSS receiver and the COR from the boom pin, as calculated by the system in X, Y, and Z values.
Offset from boom pin (North)
Offset from boom pin (Elevation) Length and width calculated by the system. The system uses length and width of the machine to draw the machine icon on the display. Use these two fields as a quick check that your measurements are correct.
Machine length and width (meters)
Body Sensor Roll angle (degrees) The roll and pitch angle offset of the body sensor, calculated by the system assuming the machine is parked on flat ground.Note: Use a UTS or spirit level to calculate these values when parked on ground that is not flat.
Pitch angle (degrees)
Sensor Placement- Boom Sensor
- Stick Sensor
- Bucket Sensor Side of machine (Left, Right) Side of the machine. as seen from the cab.
Sensor on linkage Ticked if there Is a sensor on the linkage.
Note: Mount on linkage, not on bucket
Sensor Offsets- Boom
- Stick
- Bucket Offset angle (degrees) The offset angle of the sensor, calculated by the system from an imaginary line drawn pin to pin along the centerline: Boom A-B; Stick B-G; Bucket G-J.
Linkage- DG
- GH
- FH
- DF
- DGB Angle
- HGJ Angle Distance (meters) The distances and angles the software calculated, with the lengths, or straight sides of the angle, calculated pin to pin along the centerline.
Angle (degrees) Modifying the Calibration Values
Use the "Calibration Summary" dialog to review all values.To open the "Calibration Summary" dialog, complete these steps:
Enter "$ Calibration Menu" in the master.txt file.The "Calibration" > "Calibration Summary" item appears in the main menu of the on-board software.
Select "Calibration" > "Linkage Calibration Summary" and enter data into any of the fields in the "Calibration Summary" dialog.
Touch one of the following:"Cancel" - Start the wizard again at the "Choose Method" dialog. All edited data will be lost."OK" - Store the data in the calibration file.Validating the Calibration
At minimum, verify that the position of the center bucket tooth is within acceptable limits of the "Blade Center" item in the Positions diagnostic window.Note: The "calibration.bak" file is the second copy of the most recent "calibration.txt" file, not the backup copy of the original or existing "calibration.txt" file of the machine. Make a copy of the existing "calibration.txt" file from "D:\caes\config" before starting this work.To validate the calibration, complete these steps:
Mark a location on the ground.
Have a surveyor record "Northing", "Easting", and "Elevation" of the point.
Move the center of the bucket
