1、使用环境：放置光谱仪的实验室应该防震，洁净，通风干燥（如南京麒麟生产的QL-5800A型直读光谱分析仪的环境要求：温度23正负5之间，适度在15-70%之间），一般来说直读光谱仪的相对适度应该小于80%，室内温度应该保持在0—50度之间，在同一个校准周期内室内温度变化不超过5摄氏度。

1, the use of the environment: place spectrometer laboratory should be shockproof, clean, dry and ventilated (such as type QL-5800A direct reading spectrometer Nanjing kylin production environment requirements: 23, the temperature of plus or minus 5 moderate between 15-70%), general spectrometer was relatively modest should be less than 80%, the indoor temperature should be maintained at between 0 - 50 in the same degree, the calibration period of indoor temperature more than 5 degrees celsius.

2、现场电源电压要求：QL-5800A型直读光谱分析仪的电源电压一定要是220V，千万不能用380V电压，因为HX-750型只是过流保护，没有过压保护，并且电压220V变化小于10%，频率50HZ，变化小于2%，并且一定要接地良好。

2, the power supply voltage requirements: power supply voltage type QL-5800A direct reading spectrometer must be 220V, do not use the 380V voltage, because only HX-750 type overcurrent protection, overvoltage protection and no less than 10%, voltage 220V, frequency 50HZ change, change is less than 2%, and must be well grounded.

3、检查氩气瓶是否有氩气，并且必须是纯度99.99%以上的高纯氩气，氩气的纯度与流量对分析测量值有很大影响.检查氩气是否与主机，压力表正确链接，打开氩气阀，检查氩气压力是否在10bar以上。

3, check whether the argon argon gas cylinders, and must be more than 99.99% of the purity of high purity argon, argon flow rate and purity have great influence on the analysis of the measured value. Check whether the host and the argon pressure gauge, the correct link, open the argon valve, check whether the argon pressure in 10bar to.

4、开机后，检查气压温度等条件是否满足仪器正常使用的要求。一般主机压力显示在5-5.5之间，温度在38正负1之间，一切正常时候就可以开始其他操作。

4, after opening the machine, check the pressure temperature and other conditions to meet the requirements of the normal use of the instrument. The general host pressure is displayed between 5-5.5, and the temperature is between 38 and 1. All the other operations can be started at normal time.

5、在开机之后到可以测量的这段时间大约在10分钟左右，在等待过程中可以先进行式样打磨，试样打磨对于测量也很重要，如打磨偏细则测得碳含量偏低，如打磨偏粗则测得碳含量偏高，对于试样的打磨粗磨后，最好用40#的砂子细磨。同一点也不能进行2次激发，否则结果也有偏差。样品表面纹路清晰，无缩孔，无砂眼则可进行测量分析，打磨好的试样表面不可以有手触摸，这是人为操作误差中常见的误差，一定要严格按安全操作规程操作。

In 5, after this period of time to boot can be measured in about 10 minutes, waiting for the process can be carried out style grinding, grinding specimen is also very important for measurement, such as grinding partial details the measured carbon content is low, such as coarse grinding, the measured carbon content is high, the samples of coarse grinding grinding after the best use of the 40# sand fine grinding. There is no 2 excitation at the same point, otherwise the result is also biased. The surface of the sample lines clear, no shrinkage, no blisters can be measured, grinding surface can not have good touch, this is the common error of human errors, must strictly follow the safety operation procedures.
