ＪＥＭ－１２００ＥＸ电镜是用微机控制的高性能电镜。它的真空系统是由两台微机联机协调控制。真空系统电路控制的功能可分为二个，一是进行真空系统的程序控制，另一是将皮拉尼的电流值进行ＡＤ转换后输入到微机８０８０Ａ。真空系统在工作中，因为外部与内部（包括电源...
The JEM-1200EX electron microscope is a high-performance electron microscope controlled by a microcomputer. Its vacuum system is coordinated and controlled by two microcomputers. The function of the vacuum system circuit control can be divided into two, one is to carry out the program control of the vacuum system, and the other is to input the current value of Pirani to the microcomputer 8080A after AD conversion. Vacuum system at work because of external and internal (including power supply...
