全文如下:
8.4 Calibration(校验)
8.4.1 Calibration(校验)
By clicking Calibration on the menu bar and then Calibration, you access the CALIBRATION-CALIBRATION MENU (fig. 8.4.1).
点击菜单栏里的校验,你将访问校验…校验菜单。
This menu is used to calibrate the system for the different gases you have to analyze.
这个菜单用来通过不同的标气来校验你的分析仪。
Be sure to first configure all parameters of the system that you find in the CONFIGURATION-SYSTEM MENU and in the CONFIGURATION-CYCLE MENU. The analyzer must be properly started and purged before the execution of calibration.
确定系统第一次设定的全部参数,系统参数包含配置…系统菜单和配置…周期菜单。分析仪在校准完成之前,必须完全起动和净化。(即热机稳定和气源净化)。
Then, specify the concentration of your span gas in the grid (span gas columns). This corresponds to the concentration of impurities found in the cylinders used for calibration. Click on the Enable button. This imposes ranges for integration based on the values specified in the CONFIGURATION-CYCLE MENU and those specified for span gas in the CALIBRATION-CALIBRATION MENU. These ranges are displayed in the Range column.
然后,在格子里输入量程气浓度(量程气栏)。这个值是被用于校准的钢瓶
气相应杂质浓度。点击激活键。这个强加的量程就是建立在你输入的配置…周期菜单和校验…校验菜单里的量程气的输入值上。这些量程值显示在量程栏里。
Example:例如:
• If 100 is set in the CONFIGURATION-CYLCE MENU with a range factor of 5,
如果配置…周期菜单设置一个量程值为100,量程因子为5,
then:然后
Range 2 ⇒ between 0 and 100 量程2在0…100之间;
Range 1 ⇒ between 0 and 20 量程1在0…20之间
Then if 75 is set as the span gas, Range 2 is selected for calibration.
那么如果量程气是75,量程2将被选择为校准量程。
• If 25 is set in the CONFIGURATION-CYLCE MENU with a range factor of 10,
如时在配置…周期菜单里设置一个量程为25的值,量程因子为10,
then:那么:
Range 2 ⇒ between 0 and 25;量程2在0…25之间;
Range 1 ⇒ between 0 and 2.5 量程1在0…2.5之间;
Then if 2.4 is set as the span gas, Range 1 is selected for calibration.
如果量程气为2.4,量程1将作为校验量程。
Calibration enabled will be displayed in the RUN-REAL TIME CHROMATOGRAM MENU. It is suggested and of common sense to do the calibration in Automatic injection mode. This allows a better gas equilibrium.
校验激活显示在实时分析菜单里。它将默认采用自动进样模式进行校准。这需要一个较好的气体平衡环境。
NOTE: When calibration is enabled, you can’t change neither range configuration nor span gas values.
注意:当校验被激活,你不能改变量程配置,也不能改变量程值。
