摘要
X线机mA控制电路由mA予置电路和mA检测电路组成；为有效控制X线管管电流，设置了较多的安全与辅助电路．岛津UD150B－10X线机mA电路的故障全部以毫安（mATrouble）提示符显示，这给具体故障的判定带来困难．要文主要讨论出现毫安（mATrouble）提示符后如何正确准确判定mA电路的故障。
X-ray machine mA circuits are generally composed by mA Pre-set circuits and mA detect circuits.To effectively control the tube current,there are many safety circuits and auxiliary circuits in mA control circuits.The trouble of mA circuits of HD150B-10 displays 'mA Trouble'promptly on the plasma display;however,it is dif-ficult to discover the actual trouble in the circuits because the mA control circuits are interconnected. In this paper,the question we discuss is how to check and shoot quickly and correctly the trouble of mA circuits,after the prompt appearance of 'mA Trouble' on the plasma display.
