氙气老化箱说明书

4.0. operation操作The section explains how to start the Weather – Ometer R, run a standard test, create a stop schedule for a test, and program a custom test. Once these steps have been mastered, the operator can rely on the prompts in the touch screen to manipulate test programs. Refer to section 3.6 to review the description of the parameter input techniques.本节说明如何使用氙气仪来进行一个标准试验，随机停止试验并安排自定义测试。

一旦掌握了这些步骤，操作者可以依靠触摸屏上的提示来操作测试程序。

参考3.6节，可以回顾参数设置的叙述。

4.1. instrument start up启动仪器Before applying power to the instrument（工具）, complete the setup, connection, and lamp installation procedures. When the setup procedures are complete, confirm the following:●Power at the wall disconnect switch is off.●The red power switch is off (O).●The working xenon lamp is installed.●Air, Dl and tap water supplies are on.●Instrument air pressure regulator is set to 552 KPA (80 psi).●Removable storage media card is inserted or DAQ system connected for datalogging.在拥有操作权限的前提下，完成机器的安装，连接，以及灯的安装（程序）。

当安装程序完成后，确认以下情况：●墙壁上的开关处于关闭的状态。

●红色电源开关关闭（O）。

●工作氙气灯已安装OK。

●空气，消旋和自来水正常开始。

●空气压力仪表调节设置为552帕（80磅）。

●移动存储介质卡插入或数据采集系统被连接，来采集数据。

1) Turn on power at the wall switch.2) Turn the instrument power switch on (I).3) Confirm that the Touch screen is operating. And I.D. screen will automatically change to the directory page.4) Confirm that the chart recorder (if included) is on. If not, press the ON button inside the lower right-hand corner of the chart recorder.5) Wait a few minutes to allow the instrument to fill the lamp cooling water reservoir. During first use, or use after the instrument has not been in operation, open the lower instrument doors and panels and check the water lines for leaks. Water will flow through the xenon lamp replacing the air with water.1)打开电源开关（在墙上）。

2)打开仪器电源开关（I）。

3)操作触摸屏，身份验证后屏幕会自动更改实验目录页面。

4)证实图表记录器（如果有）正常。

如果不正常，按下右下角的图表记录仪按钮。

5)等几分钟使仪器填补氙气灯冷却水。

第一次使用或很长时间未使用时，开下门和面板和检查水管是否泄漏，水流过氙灯时更换空气和水。

4.2. Preliminary settings 初步设置。

Before running a test, ensure that the settings in the following touch screen pages are as specified, or in conformance with requirements of the test method to be conducted.测试之前，确保按照显示屏指定的参数进行设定，或者在符合要求的测试方法下进行。

4.2.1. Unit settings page configuration1)On the Directory page, touch the Unit Settings button. The page below appears.2)Set the parameters according to the instructions below.Enabling a safety cut out: Enable a safety Cut Out by selecting Warning or Shutdown in the dropdown menu box. When set to Warning, the triggered cut out provides only a warning message in the main p age “Message:” box. When set to shutdown, the triggered cut out will cause the test program to be stopped and the instrument to enter cooling mode. Set a cut out to disabled to disable it.Irradiance cut out: This is the maximum irradiance set point tolerance allowed during operation. If the irradiance level exceeds this tolerance due to a malfunction, a warning or shutdown response will be initiated. It is set as an additive amount below and above the test set point.For exampleIf the test irradiance set point is 0.55 W/m2 and you wish to have a warning or a shutdown if the irradiance level goes more than 0.1 W/m2 out of tolerance (i.e., less than 0.45 or greater than 0.65 W/m2), set the cut out to 0.10.To adjust the irradiance cut out setting, touch its value box and a keypad appears. Touch in the desired value, then touch the enter button.Chamber temp cut out: this is the maximum chamber temperature set point tolerance allowed during operation. If the chamber temperature exceeds this tolerance due to a malfunction, a warning or shutdown response will be initiated. It is set as an additive amount below and above the test set point.For example, if the chamber temperature set point is 65℃and you wish to have a warning or a shutdown if the temperature goes more than 5℃out of tolerance (i.e., less than 60.0 or greater than 70℃), set the cut out to 5.0.To adjust the chamber temp .cut out setting, touch its value box and a keypad appears. Touch in the desired value, then touch the enter button.Relative humidity cut out:This is the maximum relative humidity set point tolerance allowed during operation. If the humidity level exceeds this tolerance due to a malfunction, a warning or shutdown response will be initiated. It is set as an additive amount below and above the test set point.For example, if the relative humidity for test is 65% and you wish to have the test stopped if relative humidity level rises to more than 60% or falls below 40%, set the cutout to 10.0.To adjust the chamber temp .cut out setting, touch its value box and a keypad appears. Touch in the desired value, then touch the enter button.Cut Out Time Delay: This delay defines how long the operating parameter must be continuously out of tolerance before the cut outs active. This setting applies to all the cut outs. This delay must be determined by the user with respect to specimen sensitivities and any set-point variation guidelines indicated in the applicable test method.To adjust the cut out time delay setting, touch its value box and a keypad appears. Touch in the desired value. Touch the enter button.Max. BPT: this is the maximum allowed black panel thermometer (sensor) temperature. When activated, it initiates cooling mode and sets the running test to "stopped." set it to 20℃above your test maximum BPT, or leave it at the default of 120℃.Recommended Max BPT (Bronchial provocation test) Cutout SettingThe Max BPT cut out should be set 20℃above your maximum test BPT temperature (or left at the default of 120℃). This cut out has a 60 second delay to prevent false tripping.最大BPT设置在最高试验温度的20℃以上（默认120℃）。
