    • A process calibrator is formed with functions of a fieldbus communicator. Preferably, functions of a fieldbus communicator support several fieldbus protocols, and it is provided such that the use of it does not hamper the functioning of a process calibrator. This has been achieved by providing the process calibrator with a pair of fieldbus connecting terminals for measuring of the fieldbus signal. The process calibrator comprises a processor, and the pair of fieldbus connecting terminals comprises a signal terminal and a ground terminal. The process calibrator further comprises at least two parallel fieldbus protocol units between the processor and the signal terminal of the pair of fieldbus connecting terminals. Each fieldbus protocol unit is dedicated to its respective fieldbus protocol. Further, the process calibrator comprises a selection unit for selecting a fieldbus protocol unit and a voltage unit for being between the terminals of said pair of fieldbus connecting terminals, which voltage unit is arranged to adjust the voltage and the impedance according to the selected fieldbus protocol unit. The selecting unit is controlled manually through the user interface. The user interface is realized by a touch screen or a combination of a touch screen and keyboard or only by a keyboard.
    • 过程校准器由现场总线通讯器的功能组成。 优选地,现场总线通信器的功能支持若干现场总线协议,并且其被提供使得其使用不妨碍过程校准器的功能。 这已经通过为过程校准器提供一对现场总线连接端子来实现,用于测量现场总线信号。 过程校准器包括处理器,并且该对现场总线连接端子包括信号端子和接地端子。 处理校准器还包括处理器和该对现场总线连接端子的信号端子之间的至少两个并行现场总线协议单元。 每个现场总线协议单元专用于其各自的现场总线协议。 此外,处理校准器包括用于选择现场总线协议单元的选择单元和用于在所述一对现场总线连接端子的端子之间的电压单元,该电压单元被布置为根据所选择的现场总线协议来调整电压和阻抗 单元。 选择单元通过用户界面手动控制。 用户界面通过触摸屏或触摸屏和键盘的组合或仅通过键盘来实现。
