Calibration Weight
Calibration weight is the weight that was used to calibrate the application. The calibration weight is merely used as a multiplier. The load in the bucket during the calibration relates mathematically to the calculated weight of the bucket. Use the standard method of entering data for the display to input the new calibration weight. The new calibration weight is used for all future bucket weight calculations and the displayed bucket weight.Note: Manually adjusting the calibration weight is not recommended for fine-tuning the system. For this purpose, use the Simple Calibration procedure.Pre-Calibration Steps
Before any system calibration (not necessary for Simple Calibration), the following steps must be performed:
Place the ride control in the AUTO or OFF position.
Exercise the machine linkage by performing 5-10 full dig dump cycles to ensure that the implements are properly lubricated.
Ensure that the hydraulic oil temperature is higher than 40° C (104° F).
Park the machine on a flat, level surface to perform the calibration.System Calibration
Perform the following steps to calibrate the system using the Display.
Enable Service Mode.Reference: Refer to Systems Operation > Service Menu of this document to Enable Service Mode.
Go to the calibration submenu.
Select payload calibration.Perform a full calibration (empty and full bucket calibration) after the following conditions occur:
An Out of Calibration fault becomes active
Major linkage service
Sensor repair
Bucket changeEmpty Bucket Calibration
The first calibration is the Empty Bucket Calibration. To perform the Empty Bucket Calibration, follow the steps below:
Select the Empty Bucket Calibration.The button will turn blue and the Empty Bucket Calibration Warning Screen will appear.
Read the Warning Screen using the Down Arrow to progress through the pages.
Press the OK button.The button will turn blue and the Empty Bucket Calibration start screen will appear.
Press the OK button.The button will turn blue and the Empty Bucket Calibration Setup Conditions screen will appear.
Use the DOWN Arrow to scroll through all the Setup Conditions.
Once the Setup Conditions are met, press the NEXT button.Conditions include:
Set ride control to the AUTO or OFF position (If equipped).
Verify that the bucket is empty.
Press the OK button.The button will turn blue and the remaining Setup Condition Screens will appear if necessary. If the Setup Conditions have been met, the screen will skip that step automatically.Conditions include:
Exercise implements to warm hydraulic oil above 40° C (104° F). If the hydraulic oil drops below 30° C (86° F) after passing this step, the calibration will come back to this step.
Slowly place the bucket into the full rackback position.
Slowly lower the linkage to the minimum position. Bottom-out the lift cylinders.
Set Engine Speed to High Idle.Note: If at any point during the calibration the setup conditions are no longer met, the calibration will return to the unmet condition step. All steps completed after this unmet condition will need to be completed again.
Release the Levers.The operator will be warned that the next set of lifts will be performed at Slow Lift Velocity.
Press the NEXT button.
Lift and lower the empty bucket at least two times.If the second full lift does not match the first full lift, the operator will
