Model 4020中文操作手册
4 操作本部分介绍如何设置和操作Model 4020分析仪。
4.1和4.5介绍准备步骤，从4.7开始介绍实际的操作。
4.2 事先断电检查在开始使用分析仪之前应断电检查，检查内容如下：1.看样气和载气的安装是否与安装和应用部分的要求一致（chapter 3）。
保证这些气体的安装在正确的位置，并且正确地接到分析仪的后部。
2.检查电路安装是否与安装部分（chapter 3）和输入输出表中的用法说明一致。
3.检查电路板和电缆/线的安装/连接是否正确。
4.确定记录器和报警器安装正确。
4.3 进入操作状态1.打开电源2.完成下述的空气调节之后，需要预热至少两个小时（加热传感器和取样系统）。
预热时间出厂时已经由软件设置好。
预热时，禁止点火。
4.4 气体调节4.4.1 空气1.调节空气瓶上的减压阀，将空气的压力调节到30psig。
2.调节仪器上的空气减压阀，将空气压力调节到指定的空气压力。
等空气流过传感器和预热完成之后，调节其他气体。
4.4.2 样气样气瓶压力调节到30psig（或者与样气压力匹配的压力），调节仪器上的样气调节阀，将样气压力调节到指定的样气压力。
4.4.3 标气1.将标气通入分析仪。
在样气和标气之间需要一个三通阀来实现二者间的切换。
2.将标气压力调节至30psig或者与样气压力匹配的压力。
3.调节仪器的样气压力，直到指定的样气压力，同时，旁路流量计读数为0.5到1.0SCFH。
4.4.4 燃烧气1.打开气瓶上的主阀门，将气瓶压力调节到30psig（或与样气压力匹配的压力）。
2.缓慢地打开气瓶上第二个阀门，以避免仪器上燃烧气减压阀受到过大的压力冲击。
注：LED红灯灭后，才能调节燃烧气。
4.5 点火当预热倒数计时器读数为零（传感器预热计时器）时，黄色加热器指示灯闪（表示温度控制其将温度保持在设置点上），红色点火失败指示灯亮。
预热完成后，4020会自动尝试点火，如果自动点火失败，一段时间后仪器会重新尝试点火，如果五次自动点火失败，就会显示一个点火失败信息。

Using a traditional multimeter for this measurement can lead to inaccurate results since they typically employ the shunt resistance technique for measuring current.The DMM4020offers an improved method for measuring low currents.By using a current-to-voltage op amp technique,the DMM4020can make current measurements with1nA of resolution and with minimal loading affect on the circuit under test,giving results that reflect real-world operation of the device.Designed to Make Your Work EasierThe DMM4020multimeter is designed with the ease-of-use and familiar operation you expect from Tektronix.Intuitive OperationDedicated front-panel buttons provide fast access to frequently used functions and parameters,reducing setup time.You no longer need to search through software menus tofind the function youneed.Limit compare mode on the DMM4020.Setup Buttons for Your Common MeasurementsWith six setup buttons on the front panel,you can save the settings for your most common measurements.Simply set up the meter for a measurement, then press shift followed by a setup button to save the measurement settings.Now each time you perform that measurement,you simply press the appropriate setup key.Dual DisplayWith the unique dual display,you can measure two different parameters of the same signal from one test connection.Limit CompareThe limit compare mode provides pass/fail indicators to quickly show if a test passes or fails to help eliminate mistakes,especially for results that are close to the limit.Simple and Accurate4-wire MeasurementsPatented split terminal jacks for the2×4ohms function allow you to perform 4-wire measurements using only two leads instead of four.Special test lead accessories are available to enable you to establish the connection.You get excellent resolution and accuracy plus the convenience and ease of using a single pair of leads.Easy Connectivity to Your PCThe RS-232port on the back panel can be used to connect to your PC.A USB to RS-232interface adapter cable is included standard with the DMM4020for connecting to your PC’s USB port.Digital Multimeters—TektronixDMM4020Signal Express acquiring data from Tektronix DMM4020and DPO3052.Connect Your Bench for Intelligent Debug Easily capture,save,and analyze measurement results from your multimeter with the special Tektronix Edition of National Instrument’s LabVIEW SignalExpress™software.Every DMM4020multimeter ships with a free copy of the Limited Edition version of SignalExpress for basic instrument control,data logging,and analysis.The optional Professional Edition offers over200built-in functions that provide additional signal processing,advanced analysis,sweeping,limit testing,and user-defined step capabilities.SignalExpress supports the range of Tektronix bench instruments*1, enabling you to connect your entire test bench.You can then accessthe Signal Express used to export DMM4020data into Excel.feature-rich tools packed into each instrument from one intuitive software interface.This allows you to automate complex measurements requiring multiple instruments,log data for an extended period of time,time-correlate data from multiple instruments,and easily capture and analyze your results, all from your PC.Only Tektronix offers a connected test bench of intelligent instruments to simplify and speed debug of your complex design. Performance You Can Count OnIn addition to industry-leading service and support,every DMM4020 multimeter comes backed with a three-year standard warranty.*1NI LabVIEW Signal Express supports the following Tektronix instruments:MSO/DPO4000/3000/2000 Series oscilloscopes,TDS3000C/2000B/1000B Series oscilloscopes,AFG3000Series arbitrary/function generators,DMM4050/4040/4020Series digital multimeters.3Data SheetCharacteristics General SpecificationsVoltageCharacteristic Description100V Setting90V to110V120V Setting108V to132V220V Setting198V to242V240V Setting216V to264VFrequency47Hz to440HzPower Consumption15VA peak(10W average)DimensionsDimension mm in.

第一章 分析仪校验规程
自动化设备检测与校验手册第一章分析仪校验规范1 目的为规范在线使用分析仪的校验工作，特制定本规范。
2 适用范围本规范适用于本公司所有在线运行的分析仪，包括磁氧分析仪、总碳氢分析仪、氧分析仪、红外气体分析仪、热导气体分析仪、微量水分析仪和微量氧分析仪。
3 主要内容分析仪在安装后投运前必须进行校验后方能启用。
在正常运行中校验周期为每月一次，若中途发现测量值误差过大，也应及时给予校验，以确保仪器仪表的准确度。
3.1 磁氧分析仪（例如：TELEDYNE 3010M）在正常生产时每天对分析仪进行一次巡检，查看分析仪面板显示值无波动，流量指示在正常位置。
磁氧分析仪每月校验一次，若中途发现测量值误差过大，也应及时给予校验，以确保仪器仪表的准确度。
3.1.1 校验气和工具的使用零点气：O298% ，终点气：纯O2≥99.995%。
常用工具：扳手和检漏装置。
3.1.2分析仪的外观检查、气密性检查以及气路连接与压力的检查3.1.2.1检查分析仪的外观是否清洁，接口有无腐蚀，电缆连接是否正常。
3.1.2.2 对所有管线进行泄漏检查，特别是样品出入口的连接。
3.1.2.3检查使用的标准气是否正确，气路连接是否正确，调整标准气减压阀，要求标准气的输出压力与样气压力一致。
3.1.3 校验3.1.3.1 分析仪面板上的“ZERO（零点）”键用于进行零点校验，校验一般采用Auto（自动）模式。
首先通入零点气，在前面板将样气流量调至最小，将测量开关置于“零点”位置，慢慢调节流量调节阀，将流量调至通样气时一致。
待面板显示数值稳定后，查看是否与标准气数值显示一致，若不一致则需要进行零点校验。
具体步骤如下：按下“ZERO”键进入零点校验校第一章分析仪校验规范验功能，屏幕显示ZERO：Settling：AUTO，按下Enter键进入自动校验模式（也可通过△▽键选择MAN（手动）模式进行校验）；屏幕显示，设置自动校验的锁定时间（在设定时间范围内，未完成自动校验，分析仪将自动进入下一锁定周期，继续进行校验，如此循环往复，直至校验完成为止）；按下Enter键进入下一菜单，屏幕显示ZERO Val：***，设置完零点气校验值，按Enter键开始自动校验，整个过程自动完成，中途不能按任何键，否则会导致自动校验的中断，校验完成，自动进入测量状态，再进行终点校验。

阳极电源
• 高压阳极电源的元件安装在阳极电源印刷
电路板上。高压调节是用串联的齐纳二极 管来实现的。此电路的设计很简单，因为 阳极电路所需的电流非常小。通常正输出 电压为125 V，允许输出波动为＋/- 10 V。
火焰保护电路
• 当发生火焰熄灭时，热敏电阻控制的晶体
管开关电路使继电器动作。此继电器操纵 面板上的指示灯和燃料气截止电磁阀，以 警告操作人员发生了火焰熄灭的情况。此 燃料气截止电磁阀使氢气流中断。
品系统部件的恒温室温度。热敏电阻和加 热元件均位于恒温室内，而电路元件的均 衡回路安装在温度控制印刷电路板上。应 用一个温度上限开关保护恒温室不会达到 过高的温度，因为如果温度控制系统失效 的话，过高的温度是可能发生的。

火焰离子化检测器
检测器
不锈钢火焰离子化检测器的上部有圆柱形收 集极电极，高压（＋260 VDC）阳极点火器线 圈和火焰保护电路传感用的热敏电阻。 收集极通过一根同轴电缆连接电量计－放大 器印刷电路板。虽然此电缆和接头都是供同 轴连接用的，但实际上此电缆只是用作有屏 蔽的单芯导线。
警告：在阳极点火器线圈上有危险的高电压（＋260 VDC）。 在没有关闭电源和拔下电源线之前，决不可试图断开点火 器线圈的电缆，也不可拆卸任何火焰离子化捡测器的部件。
火焰点火电路
• 火焰点火电路包括阳极－点火器电极（在
捡测器内），变压器和微处理器控制的继 电器。在升温定时器倒计时结束后火焰点 火电路自动通电。
• 如果自动点火失败，将显示一条说明报文，
随后可同时按下向上（Up）和向下（Down） 键而手动点燃火焰。
温度比例调节电路

• 燃料气：7 psig
• 样品气： 3.5 psig
具体应用数据
• 旁路流量： 内置流量计读数为最少0.25 SCFH（标准立方
英尺/小时）
• 推荐的支持气体： 辅助气体的
助燃空气：无烃类的干燥压缩空气
•
零点气： 无烃类的干燥氧气（有证书）
•
满量程气： 含80%满量程（或ppm）甲烷的氧气
（有证书）
• （在原文中以上有些数据是手写的，在译文用下划线表示
――译注）
• 此满量程气含已知量甲烷，并必须附有以甲烷计的烃类浓
度证书。
助燃空气
助燃空气：需要一个低烃类含量的干燥压缩 空气钢瓶，使检测器中保持合适的气氛。此 钢瓶应安装无油的金属膜片的二级调压阀。 如果要达到仪器的精确度，则烃类污染物的 浓度最好低于满量程读数的1%（在选用的分 析量程内）。
火焰离子检测器
样品气和燃料气在一个安装在恒温室的T形管 接头中相互混合。混合气体从传感器组件内 的燃烧器中逸出。助燃空气通过位于组件底 部的另一单独管接头进入传感器（即捡测 器）。组件的上部安装有阳极点火器，收集 极和火焰保护热敏电阻。捡测器位于机箱内 左前方，故很容易接近。
热敏电阻
• 热敏电阻是火焰保护电路的传感器。在室
温下热敏电阻的阻值是100 k范围内，而当 火焰被点燃后其阻值降低100倍。热敏电阻 和阳极－火焰保护电源电路板上的晶体管 控制电路相连。
电量计－放大器
• 收集极的电缆直接连接至位于电量计－放
大器电路板上的同轴插座。此印刷电路板 位于靠近恒温室外侧的侧面板上，（参看 图2-1）其中包括一个电量计放大器和一个 运算放大器。这些电路都是极高增益的电 流电压转换电路，其测得的输入电阻在数 百万欧姆范围内。此外，这些电路对静电 和污染高度敏感，故在操作这些电路板时 应极其小心。
4020型总烃分析仪由以下三部分组成： 1.样品系统； 2. 检测器； 3.电子信号处理，显示和控制系统。
燃料气和助燃空气
燃料气和助燃空气系统采用类似的部件。通 过在捡测器上游的限流器两端维持恒定的压 差而使流量稳定。
燃料气
燃料气：需要一个40%氢气和60%氮气混合 气的气体钢瓶，为火焰离子化燃烧器提供燃 料。此钢瓶应安装无油的金属膜片的调压阀 （二级）。 注：如果在分析中氢气为主体气体（即既是 样品气又用作燃料气），则不再需要其他的 辅助燃料气源。
