新型福克火电阻 multimeter 用户操作说明书
new version of the popular Fluke 87 DMM, the 87V,incorporates a selectable low pass filter* that allows for accurate drive output meas-urements that agree with the motor drive controller display indicator. Now, technicians won’t have to guess whether the drive is operatingcorrectly and delivering the correct voltage, current or frequency for a given controlsetting.Troubleshooting philosophyTechnicians use many different methods to troubleshoot an elec-trical circuit, and a good trou-bleshooter will always find the problem — eventually. The trick is tracking it down quickly and keeping downtime to a minimum.The most efficient trouble-shooting procedure begins at the motor and then works systemati-cally back to the electrical source, looking for the most obvious problems first. A lot of time and money can be wasted replacing perfectly good parts when the problem is simply a loose connection.Multimeter measurements on adjustable speed drives utilizing the new Fluke 87V DMMApplication NoteAs you go, take care to take accurate measurements. Nobody takes inaccurate measurements on purpose, but it’s easy to do,especially when working in a high energy, noisy environment like an ASD.Likewise, choosing the right test tools for troubleshooting the drive, the motor, and the con-nections is of utmost importance.This is especially true when tak-ing voltage, frequency and cur-rent measurements on the output side of the motor drive. But until now, there hasn’t been a digital multimeter on the market able to accurately measure ASDs. Fluke’sIntroductionIn the past, motor repair meant dealing with traditional three-phase motor failures that were largely the result of water, dust, grease,failed bearings, misaligned motor shafts, or just plain old age. But motor repair has changed in a big way with the introduction of electronically controlled motors, more commonly referred to as adjustable speed drives (ASDs). These drives present a unique set of measurement problems that can vex the most seasoned pro. Thanks to new technology, now for the first time you can take accurate electrical measurements with a DMM during the installa-tion and maintenance of a drive and diagnose bad components and other conditions that may lead to premature failure.*Patent pendingDrive measurementsInput side measurementsAny good quality true-rms multimeter can verify proper input power to an ASD. Theinput voltage readings should be within 1 % of one another when measured phase to phase with no load. A significant unbalance may lead to erratic drive opera-tion and should be corrected when discovered.Output side measurementsOn the flip side, a digital multi-meter can’t reliably read the output side of a pulse widthmodulated (pwm) motor drive,because the ASD applies pulse width modulated non-sinusoidal voltage to the motor terminals. A true-rms DMM reads the heating effect of the non-sinusoidal voltage applied to the motor, while the motor controller’s output voltage read-ing only displays the rms value of the fundamental component (typically from 30 Hz to 60 Hz). The causes of this discrepancy are bandwidth and shielding.Many of today’s true-rms digital multimeters have bandwidths out to 20 kHz or more, causing them to respond not only to the fundamental component, which is what the motor reallyresponds to, but to all of the high frequency components generated by the pwm drive. And if the DMM isn’t shielded for high frequency noise, the drive con-troller’s high noise levels make the measurement discrepancies even more extreme. With the bandwidth and shielding issues combined, many true-rms meters display readings as much as 20to 30 % higher than what the drive controller is indicating.Fluke’s new 87V multimeter,with its newly incorporatedselectable low pass filter, allows troubleshooters to take accurate voltage, current and frequency measurements on the output side of the drive at either the drive itself or the motor terminals.With the filter selected, the 87V readings for both voltage and frequency (motor speed) should agree with the associated drive control display indications, ifavailable. The low pass filter also allows for accurate current measurements when used with Hall-effect type clamps. All of these measurements are espe-cially helpful when taking measurements at the motor location when the drive’s dis-plays are not in view.Taking safe measurementsBefore taking any electrical measurements, be sure you understand how to take them safely. No test instrument is com-pletely safe if used improperly,and many test instruments are not appropriate for testing adjustable speed drives. Also make sure to use the appropriate personal protective equipment (PPE) for your specific working environment and measurements.If at all possible, never work alone.Safety ratings for electrical test equipmentANSI and the International Electrotechnical Commission (IEC) are the primary independ-ent organizations that define safety standards for test equip-ment manufacturers. The IEC61010 second edition standard for test equipment safety states two basic parameters: a voltage rating and a measurement cate-gory rating. The voltage rating is the maximum continuous work-ing voltage the instrument is capable of measuring. The cate-gory ratings depict the measure-ment environment expected for a given category. Most three-phase ASD installations would be con-sidered a CAT III measurement environment, with power sup-plied from either 480V or 600V distribution systems. When using a DMM for measurements onthese high energy systems, make sure it’s rated at a minimum for CAT III 600V and preferably for CAT IV 600V/CAT III 1000V. The category rating and voltage limit are typically found on the front panel, at the input terminals.The new Fluke 87V is dual-rated CAT IV 600V and CAT III 1000V.Refer to the ABC’s of DMM Safety* from Fluke for additional information on category ratings and taking safe measurements.*The ABCs of Digital Multimeter Safety can be found at /download/library/1263690_w.pdfOscilloscope view of a pwm motor drive signalTransformer type clamp (i200, 80i-400, 80i-600A)1Connect the clamp to the87V’s common and 400 mAinput jacks.2Select the mA/A ac function.3Place the clamp around each of the input supply phasecables in succession, recording each of the readings as theyare taken. Since these clampsoutput one milliamp per amp,the milliamp readings shownon the 87V display are theactual phase current readingsin amps.Hall Effect type (AC/DC)clamp (i410,i-1010)1Connect the clamp to the87V’s common and V/Ωinputjacks.2Select the 87V’s ac voltage function. 3Press the yellow button to enable the low pass filter. This allows the meter to reject all of the high frequency noise generated by the drive con-troller. Once the low pass filter is enabled, the meter will be in the 600mV manual range mode.4Place the clamp around each of the input supply phasecables in succession, recording each of the readings as they are taken. Since these clamps output one millivolt per amp,the millivolt readings shown on the 87V display are theactual phase current readings in amps.Output voltageTo measure the ac output voltage at either the drive or the motor terminals:1Plug the black test lead into the common jack and the red test lead into the V/Ωjack.2Select the 87V’s ac voltage function.Taking the measurementsNow let’s put Fluke’s new 87V DMM to the test. The measure-ments in the following procedure are designed to be made on a 480 volt 3 phase drive control at the control panel terminal strips,using the 87V. These procedures would also be valid for lower voltage 3 phase drives powered by either single or 3 phase sup-ply voltages. For these tests the motor is running at 50 Hz.Input voltageTo measure the ac voltage supply to the input side of the drive at the drive:1Select the 87V’s ac voltage function.2Connect the black probe to one of the three phase input terminals. This will be the reference phase.3Connect the red probe to one of the other two phase input terminals and record the reading.4Leaving the black probe on the reference phase now move the red probe to the third phase input and record this reading.5Make sure there’s no more than a 1 % differencebetween these two readings.Input currentMeasuring the input current gen-erally requires a current clamp accessory. In most cases, either the input current exceeds the maximum current measurable by the 87V’s current function, or it isn’t practical to “break the cir-cuit” to take an in-line series current measurement. Regardless of clamp type, insure that allreadings are within 10 % of eachother for proper balance.Figure 1.Output voltage reading without using the low pass filter.Figure 2.Output voltage reading with low pass filter enabled.3Connect the black probe to one of the three phase output voltage or motor terminals.This will be the reference phase.4Connect the red probe to one of the other two phase outputvoltage or motor terminals.5Press the yellow button toenable the low pass filter.Now record the reading.6Leaving the black probe on the reference phase, now move the red probe to the third phase output voltage or motor terminal and record this reading.7Make sure that there’s no more than a 1 % differencebetween these two readings(see Figure 2). The readingsshould also agree with thecontroller display, panel if available.8If the low pass filter isn’t enabled, the output voltage readings may be 10 to 30 %higher, as on a regular DMM (see Figure 1).2Select the 87V’s ac voltage function.3Press the yellow button to enable the low pass filter. This allows the meter to reject all of the high frequency noise generated by the drivecontroller. Once the low pass filter is turned on, the meter will be in the 600 mV manual range mode.Motor speed(Output frequency using voltage as a reference)To determine motor speed, sim-ply take a frequency measure-ment while using the low pass filter. The measurement can be made between any two of the phase voltage or motor terminals.1Plug the black test lead into the common jack and the red test lead into the V/Ωjack.2Select the 87V’s ac voltage function.3Connect the black probe to one of the three phase output voltage or motor terminals.This will be the reference phase.4Connect the red probe to one of the other two phase output voltage or motor terminals.5Press the yellow button to enable the low pass filter.6Press the Hz button. The displayed reading in hertz will be the motor speed (see Figure 3). This measurement couldn’t be made successfully without the 87V’s low pass filter (see Figure 4).Output currentAs with input current, measuring the output current generally requires a current clampaccessory. Once again, regardless of clamp type, insure that allreadings are within 10 % of each other for proper balance.Transformer type clamp (i200, 80i-400, 80i-600A)1Connect the clamp to the 87V’s common and 400 mA input jacks.2Select the mA/A ac function. 3Place the clamp around each of the output phase cables in succession, recording each of the readings as they’re taken.Since these clamps output 1 milliamp per amp, the milliamp readings shown on the 87V display are the actual phase current readings in amps.Hall Effect type (AC/DC)clamp (i410,i-1010)1Connect the clamp to the87V’s common and V/Ωinputjacks.Figure 5.Output current reading without using the low pass filter.Figure 6.Output current reading with low pass filter enabled.Figure 3.Output frequency (motor speed) without the low pass filter.Figure 4.Output frequency (motor speed) using the low pass filter.4Place the clamp around each of the output phase cables in succession, recording each of the readings as they are taken (see Figure 6).Since these clamps output 1 millivolt per amp, the millivolt readings shown on the 87-V display are the actual phase current readings in amps. This meas-urement would not be possi-ble without the 87V’s low pass filter (see Figure 5).Precision and safetyAdjustable-speed drives (ASDs)deliver big benefits for industry. They save energy, enable more precise process control and help motorsand equipment last longer. And now,with the new 87V button-controlled filter, technicians can precisely check voltage and frequency on ASD motors and verify that they’re operating properly.In addition to its unique ability to accurately measure ASDs, the Fluke 87V boasts a new thermometer function and provides an important line of defense against workplace accidents. Rated for use in 600 V CAT (category) IV and 1000 V CAT III environments, the 87V is engineered to withstand voltage spikes of 8 kilo-volts and reduce risks related to surges and spikes that can cause arc flashes.DC Bus measurementsA healthy dc bus is a must for a properly operating motor drive. Ifthe bus voltage is incorrect or unstable, the converter diodes or capacitors may be starting to fail.The dc bus voltage should beapproximately 1.414 times the phase to phase input voltage. For a 480 volt input, the dc bus should be approximately 679VDC. The dc bus is typically labeled as DC+, DC- or B+, B-on the drive terminal strip. To measure the dc bus voltage:1Select the 87V’s dc voltage function. 2Connect the black probe toeither the DC- or B- terminal.3Connect the red probe to the DC+ or B+ terminal.The bus voltage should agree with the example mentionedabove and be relatively stable.To check the amount of ac ripple on the bus, switch the 87V’s function switch to the vac func-tion. Some small drives don’tallow external access to the dcbus measurement without disas-sembling the drive. If you can’t access the dc bus, use the peakmin max function on the 87V to measure the dc bus voltage via the output voltage signal.1Plug the black test lead into the common jack and the red test lead into the V/Ωjack.2Select the 87V’s ac voltage function.3Connect the black probe to one of the three phase output voltage or motor terminals.This will be the reference phase.4Connect the red probe to oneof the other two phase output voltage or motor terminals.5Press the MIN MAX button.6Press the7The displayed reading in Peakmin max will be the dc bus voltage.Motor speed(Output frequency using current as a reference)For motors that pull at least 20 amps of running current,motor speed can be determined by taking a frequency measure-ment with current clamps. Until now, noise issues have prevented accurate readings using hall effect type clamps.Here’s how the low pass filter makes it possible.Motor speed using aHall Effect type (AC/DC)clamp (i410,i-1010)1Connect the clamp to the87V’s common and V/Ωinput jacks.2Select the 87V’s ac voltagefunction.3Press the yellow button toenable the low pass filter. This allows the meter to reject allof the high frequency noisegenerated by the drive con-troller. Once the low pass filter has been turned on, the meter will be in the 600 mV manual range mode.4Place the clamp around one of the output phase cables. Verify that the 87V is reading acurrent of at least 20 amps(20 mV in the display).5Press the Hz button. Thereadings now display themotor speed as a frequencymeasurement.Motor speed using atransformer type clamp(i200, 80i-400, 80i-600A)1Connect the clamp to the 87V’s common and 400 mA input jacks.2Select the mA/A ac function. 3Place the clamp around one of the output phase cables. Verify that the 87V is reading a cur-rent of at least 20 amps(20mA in the display).4Press the Hz button. The read-ings now display the motorspeed as a frequency meas-urement.Fluke CorporationPO Box 9090, Everett, WA USA 98206Fluke Europe B.V.PO Box 1186, 5602 BDEindhoven, The NetherlandsFor more information call:In the U.S.A.

高精密程控电压源设计与实现
高精密程控电压源设计与实现乐千桤;徐静【摘要】提出一种基于MCU的高精密程控电压源实现方法.PC机通过异步串口与MCU通信,远程控制D/A输出,同时使用精密电阻衰减网络压缩电压幅度,提高输出电压精度,输出电压经放大器驱动输出,增强了负载能力.根据大量的测试数据,创造性地拟合输出电压与配置电压值的函数关系,并通过软件修正系统误差和非线性误差,精度可达士1.5 μV,完全满足设计要求.【期刊名称】《现代电子技术》【年(卷),期】2008(031)012【总页数】2页(P25-26)【关键词】精密电压源;精密电阻衰减网络;D/A转换器;A/D转换器【作者】乐千桤;徐静【作者单位】成都理工大学,四川,成都610059;成都理工大学,四川,成都610059【正文语种】中文【中图分类】TN7921 引言在自动测试领域,为了检测电压型精密传感器的配套系统,需要可调精密电压源,其输入范围为0~50 mV,精度为10 μV,稳定性要求非常高。
传统的精密电压源一般采用精密电位器调节生成,需要高的D/A分辨率和抗干扰能力。
这种电压源操作不方便,而且随着温度等外界条件的变化而变化,其波动范围很难控制在10 μV内。
本文提出一种新的实现方案,采用闭环反馈控制方式,实时监控电压输出端并根据实际情况进行调整;对配置电压值和多组实际测试结果进行最小二乘拟合,得到配置电压值与理想输出值之间的函数关系,并通过软件修正了系统的非线性引起的误差,输出精度达到了±1.5 μV,提高了输出电压的稳定性。
2 硬件设计2.1 工作原理该系统硬件由高性能单片机、数/模转换器、高精密电阻衰减网络、仪用放大器和A/D转换器组成,其系统硬件结构如图1所示。
图1 高精密程控电压源系统硬件框图利用PC机输入一个设定值,通过串口将数据送到单片机;单片机根据PC机与单片机的通信协议解析串口数据,当检测接收到有效数据后,启动D/A转换器配置部分的软件,将设定值转化为数字量输出到D/A转换器;D/A转换器将单片机输出的数字量转化为模拟量输出到精密电阻衰减网络[1],衰减系数可通过可调电位器调整,衰减后的信号通过仪用放大器INA114稳压输出;同时A/D转换器开始工作,连续采集运放输出端的电压值,以串行方式送到单片机中,单片机根据A/D转换器采集的数据实时控制D/A转换器的数字输入端,修正环境温度等外界因素引起的误差,确保输出电压值满足设计要求。

2.8 数字电位器选型 数字电位器我们选择 ADI 公司的产品,根据产品型号列
表,非易失性器件的最大抽头为 1024,而易失性器件最大 抽头最大只有 256,因为非易失性器件受工艺性影响,有一 定的寿命,不能应用于频繁变化的场合,所以我们只讨论易 失器件。本方案中我们选择的数字电位器为 AD8400,它的总 电阻为 1 kΩ,拥有 256 位调节,相当于拥有 3.9 Ω 的分辨 率。这样的分辨率虽然不能单独用于微调网络,但是通过与 100 Ω 精密电阻的并联,即可满足我们的精度和范围要求 [5]。
2.4 电阻网络理论计算 并联电阻的阻值曲线虽然并不是线性的,但是在后半部
分,曲线趋于线性。数字电位器有 1000 个刻度值,1 ~ 400 为非线性区,我们抛弃不用,但是 400 ~ 1000 以为趋近线性 区,用 600 个阶梯很好的细分了约 80 ~ 90 Ω 之间 10 Ω 刻 度的 Y 值。

1 绪论
1.1 电阻模拟器的应用场景 温度监控无论在消费级产品应用,还是在工业级乃至军
工级产品都扮演着重要的角色,PT100 属于最为常用的电阻 式温度传感器,现代的电子技术很容易把电阻信号经过电桥 电路、差分放大电路转变为电压信号,再由 AD 传给微处理器 解析出温度值。虽然通过经典的电子技术能够很容易的识别 电阻信号,但是市场上却缺少能够输出任意电阻的电子产品。 在这里,我们把能够输出电阻信号的装置叫作电阻模拟器。 市场上缺少相关产品的第一个原因是因为相关产品工艺设计 较复杂,第二个原因是相关的应用场景相对较少。但是不能 说明它不重要,下面就举两个应用例子。

首先,将压缩包减压后,出现如下的程序:运行setup.exe,出现安装对话框,在对话框里边选择想要安装的文件目录:在这里目录可以由用户自定义,选择完成后点击下一步,再点击下一步,程序开始安装,稍作等待后,程序安装完成,再点击下一步,进入Pickering公司60系列LXI驱动的安装,该驱动为运行LXI系统的必要驱动,所以不建议用户取消,如果不小心取消了该驱动的安装,可以在该网址重新下载驱动进行安装,一路默认安装,在安装完驱动后,重启电脑,便可以使用该软件对LXI机箱中的40-297系列程控电阻进行操作。
2 环境软件安装软件运行需要Labview runtime engine 2014环境的支持,该环境已经集成在程序的安装包中,因此不需要单独安装。
软件需要Pickering的LXI驱动,前文已经介绍,集成于安装文件中。
三软件说明1 软件简介该软件主要用来实现对于高精度程控电阻卡的输出进行精确的控制和读取,以及对输出进行编程,从而实现在测试测量中对于精确电阻值的需求,例如在温控系统中通过对电阻值进行编程实现对于不同温度的模拟,从而达到测试控制器的目的。
2 功能介绍该软件的语言为中文,主面板如图所示:该软件分为如下几个模块:⑴板卡地址设置模块该模块可以设置板卡的具体地址,实现软件与板卡的连接,其中,设备IP 中填写LXI机箱的IP地址,该地址可以在LXI机箱的LED显示屏上找到,也可通过Pickkering的General SFP软件查找,或者通过Find LXI软件进行查找。
板卡具体的总线号与槽位号可以通过后两款软件获得,填写完毕后,点击“开始运行”,则该模块功能锁定,后续对板卡操作的模块激活。
⑵阻值显示模块该模块可以实时显示电阻卡各个通道的电阻值,用户可以轻松了解板卡当前阻值状况。
⑶直接设置电阻值模块单击模块前边的按钮激活该模块,在该模块中,用户可以通过在文本框中输入电阻值来直接对电阻卡的各个通道的电阻值进行设置,输入数字后按回车键或者单击空白处进行确定。
电阻值可以是阻值范围内的任意值,也可以是短路(0)或者开路(inf)。
⑷编程模块-手动模式单击模块前边的按钮激活该模块,在该模块中,用户可以预设多组每个通道的电阻值,包括短路和开路状态,通过“上一组”和“下一组”按钮来进行不同组的切换。
用户也可以直接通过“上一组”和“下一组”按钮中间的空白输入框直接输入自己想跳到的组别。
预设的阻值可以通过软件生成并且导入。
该模块用蓝色数字来显示当前组的阻值,还可以显示出前一组和后一组六个通道的阻值,方便用户观察。
⑸编程模块-自动模式单击模块前边的按钮激活该模块,在该模块中,用户可实现多组电阻值的自动步进变化,在设置完每一组的电阻值以及该组和下一组的延时后,点击“开始”按钮,程序开始运行,电阻值根据设定时间的不同开始步进变化。
同样预设的阻值可以通过软件生成并且导入。
该模块用蓝色数字来显示当前组的阻值,还可以显示出前一组和后一组六个通道的阻值,方便用户观察。
⑹预设阻值模块点击“新建”按钮,即可打开预设阻值模块,如下图所示,在该模块中可输入每一组六个通道相应的阻值,以及在自动模式下使用的步进延时,可以通过“保存”按钮将预设值保存为*.csv格式的文件,供载入模块读取。
⑺预设阻值载入模块该模块可以载入预设模块保存的文件,供编程模块使用,点击地址框后边的文件按钮,即可打开文件选择按钮,选择好保存的文件后,即可载入。
四测试验证软件安装完毕后,有两个方法进行测试和验证,即有实物的实际测试和没有实物的模拟测试。
1 实物测试实物测试就是在有Pickering的LXI机箱以及高精度程控电阻板卡的情况下对整个系统进行测试。
下边是具体的测试过程:①将电阻卡插入LXI机箱,将机箱与控制PC通过网线连接。
②打开电源开关,并且将PC开机。
③等LXI机箱启动后,可以在机箱控制器的显示屏上获取到一个IP地址,如图所示:④在控制PC上打开浏览器,输入获取到的IP地址,即可打开LXI的控制面板,如图所示:⑤点击“Instrument Control”,然后点击右边的“Click here to launch the Javacontrol applet”,即可打开如下面板:如果未能打开,请按照提示安装最新版的JAVA环境,即可打开。
在该界面中,左上角的窗口显示了目前插在机箱中的板卡,而右上角的窗口显示了当前选中板卡的具体信息,在该窗口中我们可以获得电阻卡的总线号(Bus)和槽位号(Device)。
⑥在获取到了板卡的位置信息以后,就可以打开我们的电阻控制软件,输入相应的板卡位置信息,点击“开始运行”,即可开始用软件来实时控制板卡。
2 仿真测试对于身边没有LXI实物的情况下,我们设计了仿真测试,即仿真出一个虚拟的LXI机箱来实现对软件的测试。
这就需要我们自行搭建一个虚拟机箱。
以下是虚拟机箱的搭建方法。
首先需要安装VirtualBox,下载地址:选择下载合适自己系统的最新版并且安装,然后下载Pickering公司的Virtual LXI device ISO,下载地址:下载完成后,打开VirtualBox,选择新建虚拟机,具体设置如下图,类型选择Linux,版本选择Ubuntu(32-bit),设置好后,点击创建,即可创建一个虚拟机。
然后选中虚拟机,点击工具栏中的设置,即可打开设置窗口,在设置窗口中,首先打开“系统”选项卡,然后在“启动顺序”窗口中只勾选“光驱”,如下图所示:然后切换到存储选项卡中,在“储存树”窗口中选择“控制器:IDE”,点击“没有盘片”,可以在右侧的属性栏里看到该控制器分配的光驱,单击选择控制器下拉菜单后边的光盘按钮,载入刚刚下载好的LXI device ISO,即可看到如下图界面::最后切换到网络选项卡,勾选“启用网络连接”,连接方式选择“桥接网卡”,如下图所示:设置完毕后,点击确定保存设置,然后运行虚拟机,就会出现如下界面:这表明我们已经成功的创建了一台LXI虚拟机箱,其中inet addr后边的IP 地址就是机箱的IP地址。
我们用浏览器连接该IP,就会出现LXI的控制面板,与实际机箱的控制面板相同。
点击左下角的Simulation,可以打开仿真机箱的设置界面,在这个界面中可以选择不同的机箱以及板卡。
在选择了正确的机箱和板卡以后,就可以运行软件进行相关功能的测试。
五注意事项i 在设置电阻值的时候不可以超过电阻本来的阻值范围,否则会导致阻值设置不成功,为了防止以外发生,系统锁死,重启后解除。
II 如果因为意外导致程序关闭,重新打开后无法连接到LXI设备,请重启LXI设备。
III 在编程-自动模式运行中切换其他模块时,需要等到自动模式运行结束或者手动按“停止”键停止自动模式的运行。
