Best Practices When Using 3D Guidance

The following best practices are recommended:

• Check and update cutting edge wear regularly.
• Maintain the machine in good condition to remove the play in joints that is caused by excessive wear.
• Ensure that the system has an accurately calculated orientation by moving the machine when prompted to do so. If the machine direction is wrong, tap the direction shortcut key to change it (press and hold the shortcut key to open the Direction of Travel screen). An accurately calculated orientation is required for accurate guidance.

UTS

• Place the UTS on a tripod, free from vibrations caused by passing machinery or the wind.
• For best accuracy, place the UTS between 15 meters (50 feet) and 200 meters (650 feet), up to a maximum of 300 meters (1000 feet), from the MT9xx target.
• Set up UTS instruments accurately using a minimum of three survey control points in a good geometric pattern.
• For UTS guidance, check the screed tip elevation against an independent known elevation before starting work and remove any differences by benching.
• Ensure that the UTS has a continuous line of sight to the MT9xx target. Check that the line of sight is maintained for all machine positions across the work area.
