ABSTRACT:
An automated process control prover system for (1) performing tasks, including tests, at the circuit loop termination on a termination base located between interconnected control room instrumentation and field equipment, (2) for performing tasks, including tests, to the circuit loop terminations at the control room instrumentation and field equipment locations and (3) for calibration of the field equipment. The prover system includes an improved termination base for allowing selective access to a predetermined number of the circuit loop terminations, a multiplexer for providing the selective access to one of the circuit loop terminations, and a computer for performing the tasks at the termination base. The prover system further includes a portable calibrator for interconnection to the circuit loop terminations at the control room instrumentation and at the field equipment locations which provides a calibration condition to a selected piece of field equipment, wire identification and two-way communication with the multiplexer located at the termination base.
