Linked Elevation Calibration
Linked elevation calibration is necessary in order to measure and record the elevation difference between the right mast mount and the left mast mount. The AccuGrade Laser system uses this measurement in order to compensate for the height difference between the mast mounts.The "Linked Elevation Calibration" menu is available only when the Linked Elevation operating mode is configured.Note: A laser transmitter and a carpenter's level are required in order to complete the Linked Elevation Calibration.Perform the following steps in order to complete the linked elevation calibration.Note: Refer to Systems Operation, Troubleshooting & Testing and Adjusting, "Display" for callout references.
Never look into a laser beam or point the beam into the eyes of other people. Set the laser at a height that prevents the beam from flashing directly into people's eyes.
Set up the laser transmitter so the laser beam is at a zero percent grade and a zero percent cross slope. Refer to the Operator's manual for the laser transmitter for instructions on for setting the grade and cross slope.Note: Caterpillar recommends the use of a laser transmitter with the following features: automatic self-leveling mode, 600 rpm min rotational speed and automatic out of level shutoff. Read the operator manual and follow the operator manual that is supplied with the laser transmitter. The tripod and laser should be located at least 46 m (150 ft) away from the machine. The laser should be located in an area where the laser will not detect reflections or any light source that could disrupt the laser. Set the height of the tripod and the laser transmitter so that the laser beam will strike the laser receiver when the receiver is positioned correctly on the machine. Set the laser high enough so that the cab of the machine will not stop the laser beam from being detected by the laser receiver.
Ensure the masts are at the lower limit.Note: Keep the height of the laser receivers as low as possible. This will help ensure greater system accuracy during calibration of the AccuGrade Laser system.
Crushing hazard! Read and understand the instructions and warnings in the Operation and Maintenance manual. Failure to follow the instructions or heed the warnings could cause serious injury or death.
Raise the blade approximately 30 cm (12 inch). Ensure that there is enough room in order to use a level under the edge of the blade.

Place blocks under the blade before checking the blade level.
Level the blade. Use a level in order to be sure that the bottom of the blade's cutting edge is level.
Place the power/setup switch in the "i" position.
Perform the following procedure in order to enter the "Installation" menu. You must perform the functions simultaneously.
Press and hold down the cursor scroll button.
Hold the right mast elevation/menu scroll switch in the DOWN position.
Press and hold down the ESC/left reset button.
Release all simultaneously.This causes the Installation menu to be shown on the display.
