Mechanical feedback (mfb) and pressure control valves are not catered for by the G040-123. 穆格 G040-123型伺服阀监测仪是一种能对穆格阀就近能对阀的流量控制，比例阀和伺服阀电气信号反馈检测的仪器。带机械反馈的压力控制阀不能用G040-123型检测仪。 The feature that makes it so versatile is the way it can test a valve while the valve is still installed in its normal operating plant. This is done at two levels, “in line” and “stand alone”. 这种仪器特点能对安装在阀台上正常工作的阀门进行多方面的检测和操作。这里有两种测试方式：在线检测和独立检测。 1.1.1 Plant (In Line) 工厂工作（在线检测） As in fig a) the plant and valve operate normally. In fig b) the Valve Checker is connected between the plant electronics and the valve such that all the plant electronics’ signals, to and from the valve, are connected as normal. The Valve Checker monitors the plant electronics’ signals and the signals back from the valve, enabling a check of the valve’s performance. 图a为电气线路与控制阀通常连接方式； 图b为伺服阀检测仪串联在电气线路和控制阀总电气线路之间，保证阀输出输入线路在正常状态。检测仪器能检测电气信号和输入给阀信号，来检测阀的性能。 1.1.2 Checker (Stand Alone) 检测模式（独立检测） In this mode the plant command is switched out while the Valve Checker generates the command to the valve and monitors the signals b
