Abstract
A code system for a device (30) that exhibits an input-output relationship characterized by an off-set and substantially linear performance (gain) comprising a resistor network (20) in cirucit with the device'"'"'s coil (22), indicative of the device'"'"'s GAIN and OFF-SET wherein the values of GAIN and OFF-SET are intrinsically coded within the value of a single resistor.

11. A method of operating a device such as a fuel injector whose performance is characterized by GAIN and OFF-SET values comprising the steps of:
-
(a) measuring the relationship of commanded signal and output to establish the GAIN and OFF-SET values; (b) attaching a control resistor to the device have a resistance value that corresponds to the values of both the GAIN and OFF-SET; (c) installing such device in its normal operational environment; (d) measuring the value of the control resistor corresponding to a particular device, (e) enabling the normal operation of the installed device; (f) generating a control signal to the device wherein such control signal is proportional to the value of GAIN and OFF-SET as determined from the resistance value. - View Dependent Claims (12, 13, 14, 15, 16)
