Abstract
A method of calibrating a linear driver system including a linear driver circuit, logic means connected to an input line of the linear driver circuit, and information storage means associated with the logic means, involves testing the linear driver circuit once assembled. A predetermined test load and a test electrical energy source are connected to the linear driver circuit. A first input test voltage is applied to the input line of the linear driver circuit and a corresponding first current level through the test load is measured. A second input test voltage is applied to the input line of the linear driver circuit and a corresponding second current level through the test load is measured. The two measured current levels are stored in the information storage means for later retrieval during operation of the linear driver system.
