Abstract:
1. A calibration device for calibrating a metering system that dispenses a product to a seeder towed by a farm vehicle to obtain and maintain a desired application rate of the product from the seeder into or on the ground, comprising: an electrical harness that electrically connects the farm vehicle, the seeder and the metering system, said electrical harness having a first console port at a first position, the first position at or near the farm vehicle and a second console port located at a second position, the second position at or near the metering system; and at least one calibration console having an input device and a microprocessor operative to calculate the application rate of the product based on the weight of a unit of product; whereby the at least one calibration console is connected into the second console port when the weight of the unit of product is being measured and inputted into the calibration console via the input device to calculate the application rate of the product and adjust the metering system accordingly and the at least one calibration console can then be connected into the first port when operating the farm vehicle to ensure the rate of product application is maintained during the course of seeding.
