ABSTRACT:
A method of using calibration instrumentation for determining the operating and reset points for a device having an input and an output. An initial courts test is conducted with a first variable input to establish value areas wherein device state changes occur. The method is suited for calibration testing of industrial instrumentation and is effective when operating and reset points need to be accurately searched over a wide range while minimizing the time required for testing.
