Purpose and scope

This procedure provides the basic requirements for evaluating field performance accuracy of a yield monitor installed on a harvester. 

The procedure defines methods to determine time delay of material flow through the harvester. 

This procedure outlines the method to select and prepare a field for testing to simulate changing yield conditions to evaluate yield measurement accuracy for varying flow rates. 

This procedure was developed for grain, fiber, and bulk crop yield monitors, but could be adapted for other crops.
