Abstract
A field device includes circuitry to successively measure a parameter related to current drawn by electronics of the field device. The measurements are provided to a prediction engine which calculates a diagnostic output based upon the plurality of current-related measurements. The diagnostic prediction provided by the prediction engine can provide an estimate of viable life remaining for the device electronics. The diagnostic feature provides on-line status of the overall status of the field transmitter.
