ABSTRACT:
The proper adjustment of a potentiometer is achieved through the use of a software routine that detects the output frequency from a thermistor circuit and compares the detected frequency with a predetermined desired frequency. A control signal is sent to either an adjustment means or a display means or both. Thus, there is no need for external frequency meters eliminating the disadvantages associated therewith to properly adjust a potentiometer. The display means will activate the proper light emitting diodes such that said comparison is displayed. The shaft of the potentiometer can then either be turned manually or automatically in the correct direction and to the correct degree so that a proper adjustment is achieved.
