1. A method of compensating a measurement and controlling a device, the method comprising:

  • determining a zero-point of a sensing system;

    determining a measurement by subtracting the zero-point from a sensed weight;

    determining a rate of change of the zero-point from a delta function, wherein the delta function defines the rate of change of the zero-point as a function of the difference between the sensed weight and the zero-point;

    updating the measurement at regular intervals based on the zero-point and the rate of change of the zero-point; and

    using the updated measurement to control a device.
