我先将这段整体贴出，然后询问，以便大家能理解题意。没有提问的地方，各位有时间也替我找找毛病。谢谢！
9.0 ANALYSER MAINTENANCE分析仪维护
The K4000NG requires very little maintenance. If the analyzer is equipped  with a trap (O2 or H2), this trap should be replaced ON in a periodic base. The frequency of replacement is a function of the sensitivity of the instrument i.e. if the instrument working range is 0-1 ppm or 0-200 ppm. Most of the time for high ppm range (>100 ppm) the trap is not required.
分析仪的维护量非常小，如果分析仪需要配置一个捕集阱（O2 or H2），
这个阱将被安装在一个定制的基座上。阱的置换频率是这个装置的一个敏感要素。如果这个装置的工作量程是0…1 ppm或0…200 ppm。在大多数情况下，测量高量程(>100 ppm)，捕集阱是不需要的。
The sample inlet moisture trap can be regenerated by following the instructions included with this trap. If the analyzer is used for process monitoring (distillation column, etc.) you may replace it once a year. In truck loading station, where the moisture level is high due to the use of quick connectors, it is a preferable to regenerate or replace it every six months. These are only guide lines and frequency of replacement may be extended or shorten based on experience. Both traps (O2 or H2) and moisture are available from Contrôle Analytique.
通过包括这个干燥器的如下说明，样品气入口的干燥器可以再生。如果分析仪用于程序控制（分裂蒸馏塔等），一年后你可能要换它。
在连接这个方面，使用快速接头，潮湿度高，它可取的地方是每六个月再生和替换它时的方便操作。这只是一个指导原则，置换频率的处长和缩短要看实际情况。两个捕集阱和干燥器应用于CA的仪器上。
The other parts of the system where maintenance is required are the diaphragm valves. Under normal condition, the valve's diaphragm should be replaced every two years.
系统的其它部分的维护如隔膜阀的维护也是必须的。在正常条件下，阀的隔膜每两年需要更换一次
