Process instrumentation calibrator is mainly used for instrument calibration process, its main feature is both independent signals Measuring unit and signal output unit, part of the process instrument calibrator and needed some measurements or electrical output Messages are displayed in the form of its own physical quantity (such as temperature, pressure, etc.). Process instrumentation calibrator (hereinafter referred to as "the calibrator") is the central control unit as the core digital calibrator Table, and its block diagram shown in Figure 1.
