Supervisor.

4.2 预防措施Instrumental Precaution

注意：操作者在使用Pyris 1时必须遵守下面的预防措施：

NOTE: The following precautions must be observed when using the Pyris 1

Thermogravimetric Analyzer.

4.2.1 当Pyris软件出现异常时不要按下计算机的Reset键。如果要关闭异常的Pyris窗口时应同时按下Ctrl+Alt+Del键，然后从任务管理其中关闭Pyris软件。

Never press the Reset button on the computer if the Pyris software appears to

malfunction. Press the Ctrl-Alt-Del keys simultaneously and select the Task

Manager. From the Task Manager, close the Pyris software.

4.2.2 在关闭PE Pyris 1设备和切断电源前，不要拆掉仪器上的任何面板。

Never remove the outer instrument cover or side panels on the PE Pyris 1 without

shutting the instrument down and disconnecting its power cord from the power

source.

4.2.3 PE Pyris 1所使用的气体纯度不应低于99.9%。 Only high-quality purge gases should be used with the PE Pyris 1. Minimum purity

of 99.9% is recommended.

4.2.4 遵守PE Pyris 1和相关设备的开启和关闭程序。

Always observe the proper startup or shutdown procedures with the PE Pyris 1 and

all related instruments.

4.2.5 通过天平室的气流流速始终控制在40-60cc/min, 建议使用惰性气体来作为天平室的冲洗气，如：氮气、氩气。

Always maintain a positive purge flow (40 – 60 cc/min) through the balance

chamber at all times. An inert gas such as nitrogen or argon is recommended as a

balance purge.

4.2.6 当加热炉的外套管移掉时禁止将加热炉抬升，否则将严重损坏PE Pyris 1的加热炉和其他部件。

Do not raise the furnace when the clear Pyrex furnace tube has been removed.

This will cause severe damage to the furnace and other components of the PE

Pyris 1 analyzer.

4.2.7 当PE Pyris 1的加热炉在升温时，将其前面的塑料保护面板放下，以避免意外接触高温的加热炉。

When the PE Pyris 1 standard or high temperature furnace is heating, keep the

protective plastic shield on the PE Pyris 1 in the down position. This will protect you

from accidentally touching the furnace when it is hot.

4.2.8 在切断电源和冷却风扇停止旋转前，不要移动PE Pyris 1。

Do not attempt to move the PE Pyris 1 while it is on. Wait until the power is off and

the furnace cooling fan has stopped spinning before moving the instrument.

4.2.9 在分析仪工作时禁止将其连接至PE Pyris 1的导线拔掉。

Do not remove cables from the PE Pyris 1 when the analyzer is turned on.

4.2.10 禁止触摸PE Pyris 1的加热炉开口，禁止向里面投入物体。

Do not touch the opening on the furnace lift mechanism or insert objects into the

opening.

5.0 定义 DEFINITIONS

5.1 TGA：热失重分析仪

TGA : ThermoGravimetric Analyzer

6.0 工作程序 INSTRUCTIONS

注意：在使用PE Pyris 1进行实验或者校正前，应先对热电偶进行检查。将温度设定至100°C后升温，如果热电偶校验正常，则显示的温度应非常接近100°C。

NOTE: Prior to performing any experiment or calibration procedure, be sure that the

thermocouple currently installed on the PE Pyris 1 is functioning properly. The

thermocouple can be checked by programming the PE Pyris 1 to 100°C and

checking the temperature displayed in the status panel. The temperature should be

close to 100°C if the instrument is calibrated.

6.1 设备的启动和测量 Start up and measurement

注意：在开机前确保动力气，天平气，参比气都已打开并调节到要求的流速。

NOTE: Make sure the Pneumatic gas, Balance gas and Reference gas are all open

and adjusted to the requirement before the Analyzer turn on.

6.1.1 按下面的顺序打开系统：

Turn the system on following order:

计算机

Computer

分析仪

Analyzer

6.1.2 运行Pyris软件，然后按下相关设备的按钮。

Execute the Pyris manager, then click on each instrument button.

6.1.3 等待每个设备的绿灯都亮起。

Wait until the green light comes to each instrument button (instrument window

opens automatically).

6.1.4 将加热炉升起，待重量读数稳定后，按下“Zero”键去除样品盘的皮重。

Raise the furnace, after the sample weight reading is stabilized, then tare the

sample pan by pressing the Zero weight button.

6.1.5 降下加热炉，在支架的保护下取下样品盘，放入样品，再将样品盘放回原处。

Lower the furnace; remove and fill the sample pan with the specimen while

supporting the sample pan with platform.

注意：当取下或放回样品盘时，必须使用支架对样品盘进行保护。由于Pyris 1的天平非常敏感易损，禁止再没有支架的保护下取下或放回样品盘。

NOTE: Always use the platform to work on sample pan. The weight balance is

extremely sensitive, so do not change sample pan without platform support.

6.1.6 从“File”中打开适当的操作程序（每个程序可以根据特殊的要求进行修改）。

Open the appropriate method from the File menu (each method can be modified

according to specific condition requirement).

6.1.7 打开“Sample Info”栏，填写Sample ID, Operator ID, Comment, File Name，同时检查初始状态栏并输入正确的系统参数。

Select the Sample Info tab and fill in the Sample ID, Operator ID, Comment, and

File Name. Also check initial state tab and program tab for proper parameter set up.

6.1.8 装入样品盘，升起加热炉。

Load the sample pan, then raise the furnace.

6.1.9 输入初始温度，然后点击“Go to temperature”键。当温度升至设定的初始温度后，点击“Sample weight”键称量样品重量，再点击“Start/stop”键，系统进入自动运行状态。
