TECHNICAL DATAFluke 830 Laser Shaft Alignment ToolConnected reliability systemIt’s a known fact—all rotating machinery is susceptible to misalignment. Machines that are well aligned at thecommissioning stage and regularly maintained will have reduced wear in couplings, bearings, and seals, all of which means reduced plant operating and maintenance costs.Accurate shaft alignment contributes to energy savings and a cleaner environment. It protects assets, extends machineavailability, and increases product quality, reducing vibration to a minimal level.Are you still using dial indicators and straightedges to ensure your shaft-driven machines are correctly aligned? If so, you could be losing thousands of dollars per year in replacement bearing and coupling costs, hours of unnecessary repair time, and crippling unplanned downtime, not to mention taking years off your machine’s useful life.When uptime matters, picking the right tool is criticalThe Fluke 830 Laser Shaft Alignment tool is easy to use andprovides you with fast, accurate, and actionable answers to keep your plant up and running. With laser shaft alignment, data is helpful, but insights are even better.Unlike using the straightedge method or dial indicators, the Fluke 830 performs complicated alignment calculations for you, meaning you’ll have the answers you need to align your machine and get your plant humming again quickly. An enhanced user interface provides easy to understand results that don’t require extensive alignment knowledge. It also offers a unique “All-in-One” result screen that shows you both coupling results and feet corrections (vertical and horizontal) in real terms, making it easy to take corrective action.Since machine downtime is costly, test repeatability is critical. The Fluke 830 uses a proven single-laser precision alignment system that provides accurate and repeatable measurement results so you can be confident you’re addressing misalignment problems properly.High-quality brackets make certain the sensor and prism don’t slip as the shaft rotates.FEATURES AND BENEFITS •Single-laser measurementtechnology means reduced errors from backlash, resulting in better data accuracy•Intuitive guided user interface quickly and easily completes machine alignments•Compass measurementmode enables flexible, reliable, and repeatable measurements using an activated electronic inclinometer•Dynamic machine tolerance check provides continuous evaluation of alignmentadjustments, so you know when your machine in acceptable range •Unique extend mode handles gross misalignment by virtually increasing laser detector size •Data protection ensures your data is there when you need it, with auto save and resume capabilityAlign coupled shafts in four simple steps:Quick, easy, precise alignments to covermore of your machines:Handling gross misalignment:When machines are well outside of acceptedtolerances, it can be difficult to get accuratealignment readings. For these grossmisalignment problems, the Fluke 830 usesa unique “Extend” mode that enables bettermeasurement accuracy by automaticallyincreas¬ing the effective sensor measurementarea. Increasing the sensor measurement areavirtually allows the Fluke 830 to address grossmisalignment quickly without the need toperform an initial rough alignment.Additional features and benefits:1. Clock mode for vertical and flangedmachines.2. Machine Flip turns over the image of amachine on screen for alignment jobs withobstructions.3. Resume mode to save your work and returnat the same step (anytime you need).1. SetupStep-by-step input of themachine dimensions.2. MeasureRotate the shaftand receive instantmeasurement verification.3. Diagnose/correctActual correction numbersare given, along with a4-level color severity scaleindicating whether yourmachine is misaligned.“Live” mode providesimmediate dynamicfeedback while you makeadjustments – eliminatingthe need to performadditional diagnostics.4. Re-measureConfirm alignment results.Then print a report,As Found & As Left, todocument the job.Fluke offers a complete line of predictive maintenance tools designed to maximize plant uptime. Whether you’re using a Fluke vibration tester to diagnose fault and severity, or a Fluke infrared camera to evaluate machine health, our predictive maintenance tools provide the answers you need to reduce unplanned downtime and decrease repair costs. The Fluke 830 Laser Shaft Alignment Tool uses asimilar measurement process as the Fluke 810 Vibration Tester, making laser shaft alignment as easy as 1-2-3-4. Just set up the unit, perform the test, evaluate the diagnosis, and check the results.A Fluke infrared camera helps you quickly identify possible machine health problems, and a Fluke vibration tester will further diagnose the problem anddetermine whether or not misalignment is present. With the Fluke 830 Laser Shaft Alignment tool, you can correct any misalignment, then verify your results with your Fluke infrared camera or vibration tester to check the machine health.Fluke predictive maintenance tools help keep your plant up and running:1Identify a potential problem using a Fluke infrared camera.2Diagnosis and repairrecommendation using the Fluke vibration tool.3Corrective action using the Fluke 830 Laser Shaft Alignment tool.4Result verification using the Flukevibration tool.Technical specificationsFluke CorporationPO Box 9090, Everett, WA 98206 U.S.A.Fluke Europe B.V.PO Box 1186, 5602 BD Eindhoven, The Netherlands For more information call: In the U.S.A. 856-810-2700 In Europe +353 507 9741 In UK +44 117 205 0408 Email:*****************Web access: ©2020 Fluke Corporation.Specifications subject to change without notice. 07/2020 6013592a-enModification of this document is not permitted Order InformationFluke 830 Laser Shaft Alignment Tool includes:Fluke 830 rugged device, sensALIGN 3 sensor with cover, reflector prism with cover, ballistic carrying case, chain-type mounting bracket with 150 mm support posts (2X), 300 mm support posts (4X), tape measure, lens cleaning cloth, device power cable and adapter, PC cable, sensor micro power cable and adapter, USB drive, USB drive cable, safety information sheet and Quick Reference GuideVisit to get complete details on these products or ask your local Fluke sales representative.Technical specifications continued...。

数字电子技术课程设计报告设计课题: DT-830数字万用表组装姓名:学院: 信息工程学院专业:班级:学号:日期指导教师:山东大学威海分校信息工程学院DT-830的焊接与装配摘要：电压表按其工作原理和读数方式分为模拟式电压表和数字式电压表两大类。

与普通的模拟式多用表相比，数字多用表的测量功能较多，它不但能测量直流电压、交流电压、交流电流、直流电流和电阻等参数，而且能测量信号频率、电容器容量及电路的通断等。

本次实验主要是焊接DT-830数字万用表及其组装，学会数字万用表的工作原理。

关键词：数字万用表、工作原理、焊接组装1 工作原理1.1数字万用表的特点数字电压表可缩写为DVM。

较之模拟式多用表，数字多用表除具有一般的所具有的DVM准确度高、数字显示、读数迅速准确、分辨力高、输入阻抗高、能自动调零、自动转换量程、自动转换及显示极性等优点外，还由于采用大规模集成电路，因而体积小，可靠性好，测量功能齐全，操作简便，有些数字多用表可以精确地测量电容、电感量、温度等，大大地扩展了功能；同时数字多用表内部有较完善的保护电路，过载能力强等等。

由于数字多用表具有上述这些优点，使得它获得越来越广泛的应用。

但它也有不足之处，它不能反映被测量的连续变化过程以及变化的趋势，如用来观察电容器的充、放电过程，就不如模拟电压表方便直观，也不适于作电桥调平衡用的零位指示器；同时，其价格也偏高，所以尽管数字多用表具有许多优点，但它不可能完全取代模拟式多用表对于DT-830数字万用表来说，它的主要特点有，（1）技术成熟，主电路采用典型数字集成电路ICL7106,性能稳定可靠；（2）性价比高，由于技术成熟，应用广泛，具有精度高、输入电阻大、读数直观、功能齐全、体积小等优点；（3）结构合理，安装简单，集成电路ICL7106采用COB封装。

1.2 数字多用表的基本原理和模拟直流电压表前端配接检波器即可构成模拟交流电压表一样，在数字直流电压表前端接相应的交流-直流转换器(AC/DC)、电流-电压转换电路（I/V）、电阻-电压转换电路（Ω/V）等，就构成了数字多用表，如图一所示。

前言1关于智能变电站传统变电站面临诸如常规互感器的动态量测范围存在局限性、缺乏统一的信息模型和信息交换模型而使电网信息共享难以实现、智能设备之间缺乏互操作、大量二次电缆对可靠性的不利影响等问题。

随着新型光电互感器技术的成熟、光通信技术和以太网智能交换技术的发展，以及IEC61850系列国际标准的颁布实施，为解决以上问题的解决提供了技术支撑，同时为智能变电站的推广应用奠定了基础。

智能变电站是变电站技术的发展方向，是坚强智能电网的建设基础和重要组成部分。

许继符合IEC61850标准体系的智能变电站自动化系统正是在上述背景下应运而生的。

IEC61850标准体系给变电站自动化技术的发展提供了有效的支撑，主要体现在建模的标准化，支持网络通信方式实现智能电子设备之间的信息交互，实现不同设备之间的互操作等。

需求的推动和技术的发展使变电站向着全数字化的方向发展，符合IEC61850的全智能变电站是发展的潮流。

许继的智能变电站产品基于成熟的软、硬件平台，信息模型和信息交换模型完全遵循IEC 61850的规范，支持互操作，其突出的特点如下：（1）数据采集数字化，采用非常规互感器提高了动态量测水平和测量精度，降低了绝缘要求，在高压系统采用节约成本效用明显；（2）一次设备智能化，IEC61850把变电站分为站控层、间隔层和过程层，过程层的智能接口可以看作是一次设备的延伸和在二次系统中的映射，便于实施精确跳合闸控制和开展设备的状态检修；（3）二次设备网络化，大量的控制电缆被数字通信网络取代，装置冗余被信息冗余取代，降低了工程造价，提高了可靠性；（4）系统建模标准化，统一的信息模型和信息交换模型解决了互操作问题，实现了信息共享，简化了系统维护、工程配置和工程实施。

You will need a front panel conversion kit for each module to be changed. Refer to the “Parts Required” section for details of the kits available. You can order these kits from your nearest Tait Dealer or Customer Service Organisation. The instructions in this TN assume the person making the changes to the equipment has good technical knowledge.This TN replaces TI-RID-457 and we have taken this opportunity to reformat the docu-ment into our latest layout. This has resulted in some minor changes to the pagination,text and illustrations. However, to avoid confusion, we have decided to mark only sig-nificant changes to the content and technical procedures with our usual vertical lines in the outer margin of the page.If you have any questions about this TN or the procedures it describes, please contact your nearest Tait Dealer or Customer Service Organisation. If necessary, you can get additional technical help from Customer Support, Tait Electronics Ltd, Christchurch,New Zealand.Note:For information on converting T800 Series II modules for use in a T800Series I rack frame, refer to the appropriate T800 Series II service manual.TN-619Parts RequiredChoose the Series I to Series II front panel conversion kit(s) you need from the list of available kits in the following table.Conversion Kit T800 ModuleT800-70-0000receiverT800-71-0000transmitterT800-72-0000exciter with rear RF outputT800-73-0000exciter with front RF outputT800-74-000050W PA with rear RF inputT800-75-000050W PA with front RF inputT800-76-0000100W PA with rear RF inputT800-77-0000100W PA with front RF inputT838/839 Only1 x 330nH SMD inductor (IPN 056-10330-02)Tools RequiredTool SizeAllen head screwdriver2mm AFflat blade screwdriver3mm AFPozidriv screwdrivers No. 1 for M3 screws No. 2 for M4 screwsTorx screwdrivers T10 for M3 screws T20 for M4 screws spanners1/4” AF for D-range locating pins5.5mm AF for M3 nuts a6mm AF for SMC connector7mm AF for M4 nutssoldersoldering irona.If you do not have a 5.5mm spanner, you can use long-nosed pliers to carefully grip the M3 nuts onthe D-range securing screws and locating pins.Page 2 of 102nd June 2000TN-619 MethodT835, T836 & T837You must make a number of modifications to convert a Series I T835, T836 or T837 for operation in a Series II rack frame. These changes can be split into two groups, mechan-ical and electrical, as described below.Mechanical These changes involve:•putting on a new front panel because of the differences inheight and width between a Series I and Series II panel;•removing the D-range 1a locating pins, as the Series II hasself-aligning guides which do not accommodate locatingpins.Electrical These changes involve making sure there is pin compatibility for D-range 1 pin 7 between the Series I module and the Series II rackframe.In Series I pin 7 is allocated to audio 1 for the T836/837, and audio 2for the T835, but in Series II pin 7 is the serial programming port.a.D-range 1 is the main D-range connector soldered directly to the main PCB.The procedure assumes you have already purchased a Series I to Series II front panel conversion kit. If not, you should purchase one from your nearest Tait Dealer or Cus-tomer Service Organisation before beginning the procedure.Step Action1.Remove the Series I front panel from the module:•remove the volume knob (T835 only);•remove the four screws using an Allen head screwdriver;•push the LEDs from the front of the panel to remove them fromtheir grommets.2.Remove both covers from the module.3.Remove the locating pins (long pins attached to either side of D-range 1)using either a spanner or a pair of pliers.Note:These pins may be screwed directly into the chassis orsecured by nuts inside the chassis.4.Replace the locating pins with M3x12 screws, spring washers and M3nuts.Note:If you have a chassis with threaded holes, you will need touse only the M3x12 screws and spring washers.2nd June 2000Page 3 of 10TN-619Step Action5.Disconnect pin 7 of D-range 1 so that audio line 1 (T836/837) or audioline 2 (T835) does not interfere with the programming line on the SeriesII rack frame:•locate D-range 1 pin 7 on the bottom side of the main PCB (theside furthest from the handle) - check the D-range connectorfor pin numbering;•desolder pin 7 and lift it away from the PCB;•to ensure that pin 7 will no longer make contact with the PCB,place a silicone sleeve over the pin or cut the pin off com-pletely;•in the T836/837 only, short the pads for pins 6 and 7 (audiolines 2 and 1) together on the PCB with a solder bridge.Note:If you still require the audio previously available on pin 7,you can access it by hard-wiring it to a second D-range.6.Replace both covers.7.Fit all parts of the Series II front panel, following Step 1 in reverse order.Note:If you have difficulty refitting the LEDs, try pushing thebody of the LED back into the grommet with a thin screw-driver or spike. Be very careful while doing this as the legsof the LED are very easy to break.Page 4 of 102nd June 2000TN-619T838/839Note:This procedure applies to the latest design T838/839 PAs which use RF power modules and are identified by the Series II style product codeT83X-X0-0300. We do not recommend converting the earlier model T838with product code T838-10 for use in Series II systems.You must make a number of modifications to convert a Series I compatible T838/839 PA for operation in a Series II rack frame. These changes can be split into two groups, mechanical and electrical, as described below.Mechanical These changes involve putting on a new front panel because of the differences in height and width between a Series I and Series IIpanel.Electrical These changes involve:•inserting and removing components inside the module toenable cyclic keying;•converting from front RF input to rear RF input.The procedure assumes you have already purchased a Series I to Series II front panel conversion kit. If not, you should purchase one from your nearest Tait Dealer or Cus-tomer Service Organisation before beginning the procedure.The conversion procedure starts on the following page.2nd June 2000Page 5 of 10TN-619Step Action1.Remove the Series I front panel from the PA as follows:•remove the four screws using an Allen head screwdriver;•push the LEDs from the front of the panel to remove them fromtheir grommets.2.Remove the side cover.3.Follow the step for whichever module you are going to modify:•T838 - go to Step 4;•T839 - go to Step 5.These modifications will enable the cyclic keying.4.T838Place *L201 (330nH SMD inductor), as shown in Figure 1.Caution:Do not use excessive heat to place the inductor or it willmelt.Remove *R120 (0Ω SMD resistor), as shown in Figure 1.Go to Step 6.5.T839Place *L211 (330nH SMD inductor), as shown in Figure 1.Caution:Do not use excessive heat to place the inductor or it willmelt.Remove *R120 (0Ω SMD resistor), as shown in Figure 1.Continue with Step 6.Page 6 of 102nd June 2000TN-6192nd June 2000Page 7 of 10Figure 1 T838/839 Component Changes*R V 111R 135R 163R 166R 173R 174T O P F I D BR V 109D 109D 103D 107S E R I E S I I O N L Y*C 203*C 204*C 206*L 201*R 201*R 202*R 204*S K 2030C 143C 145C 147C 149C 155C 173C 174C 176C 179C 180C 181C 182C 184C 185C 186C 187C 189C 215C 220C 221C 222C 223C 224C 226D 202I C 101I C 105I C 107I C 204L 105L 208L I N K 1L I N K 201Q 123Q 125Q 127Q 133Q 135Q 136Q 201R 101R 103R 104R 118R 119R 141R 142R 143R 144R 145R 146R 155R 156R 157R 168R 169R 170R 171R 172R 175R 176R 177R 178R 179R 180R 181R 182R 183R 184R 185R 186R 187R 188R 189R 190R 194R 195R 196R 197R 207R 209R 210R 212R 213R 214R 218R 220R 222R 224R 228R 229*R 107*R 122*C 123*R 116*C 212*C 213*R 211*C 121*R 105*C 103*C 101*R 120*C 124*R 102*C 127Q 137*C 217*C 219*L 211*S K 201*I C 203*I C 20500000000000000000P L 101000000000C 272C 271C 270*#I C 202R V 10900000 0000#I C 201T 839 I S S U E : 3A 220-01404-03000000000000000P L 101000000000C 272C 271C 270R V 10900000 #I C 201220-01404-03000000000T 838 I S S U E : 3A T838 - place *L201T838 & T839 - remove *R120T839 - place *L211TN-619Step Action6.Converting from front panel RF input to rear panel RF input.Remove the front panel SMC connector and coax.Fit the rear panel BNC connector:•unscrew and remove the blanking plate covering the hole inthe rear of the chassis;•carefully feed the coax through this hole and screw the BNCconnector in place;•route the coax from the BNC connector around the PCB andconnect it to *SK203 (T838) or *SK201 (T839) as shown in Figure2.Note:The coax must go down the side of the PCB and not acrossit.Caution:Do not bend the coax too tightly because you will puttoo much stress on it.7.Refit the side cover.8.Fit all parts of the Series II front panel, following Step 1 in reverse order.Note:If you have difficulty refitting the LEDs, try pushing thebody of the LED back into the grommet with a thin screw-driver or spike.
