CALIBRATION OVERVIEW

IMPORTANT: Installation of the SC1/TC1 system must be completed before calibrating the system. Refer to the machine-
specific SC1/TC1 installation manual or contact your local Raven dealer for assistance with installing the
SC1/TC1 system.

PREPARATION AND BEST PRACTICES

• For best performance, the SC1/TC1 guidance and steering system must be calibrated specifically for each
machine configuration (e.g. tractor and implement combination).
• Start the calibration process with the machine parked on a level surface with several acres of smooth ground
available.
• Ensure that the engine and hydraulic systems are at normal operating temperature and perform all calibration
procedures at typical operating RPM.
• It is recommended to calibrate in conditions as close to actual field operations as possible. Before starting the
calibration process:
•
Fold and rack booms on self-propelled applicators.
•
Disconnect any implements from the tractor hitch. Best results are obtained by completing the
machine calibration without any towed implements. Refer to Chapter 3, Initial Implement
Calibration, for assistance with calibrating the SC1/TC1 implement guidance features.
•
Verify machine measurements are correctly entered into the UT.
• During the auto-steering calibration, the machine will make several hard left and right turns. Adjust the vehicle
speed and location as necessary.
•
To pause the calibration at any time, turn the steering wheel or press the Stop button on the UT.
Tap the foot/resume switch to resume the calibration process.
•
To ensure successful auto-steering calibration, try to minimize the number of pauses.
•
If an error message is displayed during calibration, refer to Chapter 8, Diagnostics and
Troubleshooting on page 63 for possible causes and corrective action steps to be taken.

INITIAL MACHINE CALIBRATION

Initial calibration of the SC1/TC1 system consists of the following component setup calibrations:
• GPS Setup
• Terrain Compensation Calibration
• Auto-Steering Calibration
NOTE: The SC1/TC1 system can be used for GPS only or for GPS and auto-steering. The following sections
walk through the calibration procedures for both GPS only as well as GPS guidance and auto-
steering. If using the system for GPS only, the steering calibration steps will not be completed.
1. When prompted, accept Operator Liability. Refer to the Operator Liability section on page 27 for additional
information.
NOTE: The calibration wizard will be displayed the first time the SC1/TC1 module is accessed after installation
or any time the Reset SC1/TC1 option is selected. Refer to Resetting Calibrated Gains section on
page 113 for additional information about resetting the SC1/TC1 system.
2. Select the Guidance and Steering terminal from the UT menu. The Machine Selection page will be displayed.
