今天继续第9章第6段，仪器常规维护。
9.6 Routine check-up常规检查
The analyzer does not need a lot of supervision. But for accurate measurements you must be sure that:
分析仪不需要过多的管理。但是仪器的精密测量度你一定有把握做到：
1. Carrier flow is as per the value specified for your configuration. To check the carrier flow, put the injection mode in manual. Go back in «RUN» menu and watch the value. It is normal to have carrier flow deviation during a cycle. Between and before an injection the carrier flow must be correct.
载气流量按照你的仪器配置的设定值。检查载气流量，将进样模式改为手动。返回《运行》菜单并检查数值。通过这个标准，检查载气在常规状态下和分析周期期间两者之间的背离情况。在这之前，载气流量必须正确选择好。
2. From time to time, verify the oven temperature in the diagnostic menu. It must be constant and at the value specified in the configuration section in the back cover.
有时，在诊断菜单里查证柱温。这必须是一个恒定温度且背面配置章节里设定值。
3. The sample flow must be at the same value of the previous calibration procedure. This is to make sure you have the same sample volume injected. The default value of 75 sccm is OK.
样品流量必须与校验时的流量值相一致。必须确定你进的是同等体积的样品量。默认值是75就可以啦。
4. Clean cabinet fan’s filter periodically. This is very important, high internal temperature will eventually cause problems.
定期清洁你的风扇过滤网，这非常重要，内部温度高将导致产生问题信息。
