Claim Text:
1. A classification method for an injector, the method comprising: actuating the injector with a test control signal having a current level and a duration, detecting a quantity of fluid output by the injector based on the test control signal, comparing the detected quantity of fluid output by the injector with a quantity of fluid associated with the test control signal, classifying the injector based on the quantity of fluid output by the injector by determining a quantity class of the injector based on the comparison, determining a necessary control signal to yield a desired fluid output based on the classification of the injector, determining an offset time of the injector based on the determined quantity class, and accounting for any injector with a reduced stroke by adjusting the current level or the duration of the test control signal to determine the necessary control signal to yield a desired fluid output.
