1. A payload monitor adapted to provide data related to the payload of a work machine, said payload monitor comprising:
- at least one sensor adapted to transmit a sensor signal related to the load being carried by said work machine;
a processor adapted to receive said sensor signal and perform a calculation, which includes applying a first coefficient to the sensor signal, to determine the payload of said work machine, and to perform the calculation with an alternate coefficient that is used to modify the first coefficient;
wherein said first coefficient and said alternate coefficient are used in said calculation to account for distribution of payload between a front and a rear axle.

Abstract
A method and apparatus is provided for calibrating a payload monitor of a work machine. Altering the load carrying body of a work machine can adversely impact the accuracy of a payload monitor. The present invention provides a calibrating technique using an alternate coefficient that is programmed into the payload monitor. The alternate coefficient is then used by the payload monitor.

14. A method for calibrating a payload monitor adapted to calculate the weight of a payload being carried by a work machine, said method comprising the steps of:
-
determining an actual weight of said payload being carried by said machine, calculating the weight of said payload using a first coefficient related to a distribution of the payload on the work machine, comparing the actual weight of said payload to the calculated weight of said payload; and
determining an alternate coefficient to compensate for the difference between the actual weight and calculated weight of the payload, inputting said alternate coefficient into said payload monitor. - View Dependent Claims (15, 16, 17, 18, 19)
