万用表试用方法
万用表试用方法
一、外观及功能
万用表（多用表、调节表、示波表或数字多用表）是一种仪器，它具有测量和分析电压，电流和其他量的能力。
它可以用于我们的日常电气和电子领域的维修、检测、配置和测试。
它有一种独特的电路板结构，可以显示电压或电流曲线，并有多种插头，可以利用不同的设备测量不同的参数。
二、安全使用方法
1、使用万用表之前，应先检查好万用表的外观和状态，要确保整体良好无损，且控制台指示灯和按钮均可正常使用。
2、万用表应放置在干燥的通风场所，避免产生浓烟、潮湿及高温环境。
3、万用表使用前应检查电源电压是否在合适范围内，保证万用表的正常使用。
4、操作万用表时，首先应安装可靠的电池供电，使用时应将电池
分两个接头，在正负极连接好后再将正负极接入万用表接头中。
5、使用过程中，确保手持装置及其他运行位置的安全性，避免碰
撞造成仪器损坏。
6、万用表的功放开关及旋钮不能随意调节，有可能破坏仪器本身。
7、操作完成后，切记关闭万用表的电源，以防止火花及电弧的危害。
三、常见的使用方法
1、用万用表测量电源电压和电流：首先，接通测量目标的电源，
将黑色探头接入电源的正极，红色探头接入电源的负极，然后将指针
放在万用表上，把数字调节到“电流测量处”，可以获得电流大小，
再把数字调节到“电压测量处”，可以获得电压的大小。
2、示波测量：将红色探头接入检测信号的正极，黑色探头接入负极，将指针调到示波处，用时间调到适当位置，然后就可以看到曲线了，对曲线进行测量可以得到测量结果。
3、检测电路板上的信号：将红色探头接入检测信号的正。

Testing DiodesOpenAIK07F.EPSUsers ManualMeasuring AC or DC CurrentXW WarningTo avoid personal injury or damage to the Meter: • Never attempt to make an in-circuit currentmeasurement when the open-circuit potential to earth is >1000 V.• Check the Meter's fuses before testing. (See “Testing the Fuses”.)• Use the proper terminals, switch position, and range for your measurement.• Never place the probes in parallel with a circuit or component when the leads are plugged into the current terminals.Turn power OFF, break circuit, insert Meter in series, turn power on.Understanding AC Zero Input Behavior of True RMS Meters Unlike averaging meters, which can accurately measure only pure sinewaves, True RMS meters accurately measure distorted waveforms. Calculating True RMS converters require a certain level of input voltage to make a measurement. This is why AC voltage and current ranges are specified from 5% of range to100% of range. Non-zero digits that are displayed on a True RMS meter when the test leads are open or are shorted are normal. They do not affect the specified AC accuracy above 5% of range. Unspecified input levels on the lowest ranges are: • AC voltage: below 5% of 600 mV AC, or 30 mV AC • AC current: below 5% of 60 mA AC, or 3 mA ACUsing the Bar GraphMeasuring FrequencyXW WarningTo avoid electrical shock, disregard the bar graph for frequencies > 1 kHz. If the frequency of the measured signal is > 1 kHz, the bar graph is unspecified.The Meter measures the frequency of a signal. The trigger level is 0 V, 0 A AC for all ranges.AC/DC Voltage FrequencyAC Current FrequencyAIK09F.EPS⇒ To exit frequency, press YELLOW button or turn the rotaryswitch.⇒ In frequency, the bar graph shows the AC/DC voltage or ACcurrent accurately up to 1 kHz.⇒ Select progressively lower ranges using manual ranging for astable reading.Using the Bar GraphThe bar graph is like the needle on an analog Meter. It has anoverload indicator (>) to the right and a polarity indicator (±) to the left.Because the bar graph updates about 40 times per second, which is 10 times faster than the digital display, the bar graph is useful for making peak and null adjustments and for observing rapidly changing inputs.The bar graph is disabled when measuring capacitance ortemperature. In frequency, the bar graph accurately indicates the voltage or current up to 1 kHz.The number of lit segments indicates the measured value and is relative to the full-scale value of the selected range .In the 60 V range, for example (see below), the major divisions on the scale represent 0, 15, 30, 45, and 60 V. An input of −30 V lights the negative sign and the segments up to the middle of the scale.AIK11F.EPSUsers ManualCleaningWipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Dirt or moisture in the terminals can affect readings.Testing the FusesXW WarningTo avoid electrical shock or injury, remove the test leads and any input signals before replacing the fuse.Test fuses as shown below.AIK12F.EPS Replacing the Battery and FusesXW WarningTo avoid shock, injury, or damage to the Meter: •Use ONLY fuses with the amperage, interrupt,voltage, and speed ratings specified.•Replace the battery as soon as the low battery indicator (b) appears.SpecificationsSpecificationsAccuracy is specified for 1 yr after calibration, at operating temperatures of 18 °C to 28 °C, with relative humidity at 0 % to 90 %.

万用表
数字万用表使用方法文件编号修改状态工序名称一、适用范围适用于FLUKE179、FLUKE15B、FLUKE17B型号的万用表二、使用方法1 电压的测量1.1直流电压的测量：首先将黑表笔插进“com”孔，红表笔插进“”把旋钮选到直流选择档位（注意：“V－”表示直流电压档，“V～”表示交流电压档，“A”是电流档），接着把表笔接电源或电池两端；保持接触稳定。
数值可以直接从显示屏上读取，若显示为“OL”，则表明量程太小，那么就要加大量程后再测量.如果在数值左边出现“-”，则表明表笔极性与实际电源极性相反，此时红表笔接的是负极。
1.2交流电压的测量：首先将黑表笔插进“com”孔，红表笔插进“”把旋钮选到交流选择档位，然后将旋钮打到交流档“V～”处所需的量程即可。
接着把表笔接电源或电池两端；保持接触稳定。
数值可以直接从显示屏上读取，若显示为“OL”，则表明量程太小，那么就要加大量程后再测量。
2 电流的测量2.1直流电流的测量：先将黑表笔插入“COM”孔。
若测量大于400mA的电流，则要将红表笔插入“10A”插孔并将旋钮打到直流“10A”档；若测量小于400mA的电流，则将红表笔插入“400mA”插孔，将旋钮打到直流400mA以内的合适量程。
调整好后，就可以测量了。
将万用表串进电路中，保持稳定，即可读数。
若显示为“OL.”，那么就要加大量程；如果在数值左边出现“-”，则表明电流从黑表笔流进万用表。
2.2交流电流的测量：测量方法与1相同，不过应选择交流模式。
注意：电流测量完毕后务必将红笔插回“”孔。
3 电阻的测量：将表笔插进“COM”和”孔中，把旋钮打旋到“Ω”中所需的量程，用表笔接在电阻两端金属部位，测量中可以用手接触电阻，但不要把手同时接触电阻两端，这样会影响测量精确度的。
读数时，要保持表笔和电阻有良好的接触；注意单位：“Ω”，“KΩ” “MΩ ”。
4 二极管的测量数字万用表可以测量发光二极管，整流二极管等。

FLUKE179型数字万用表图解
1.数字万用表介绍
数字万用表，一种多用途电子测量仪器，一般包含安培计、电压表、欧姆计等功能，有时也称为万用计、多用计或多用表。
它可以有很多特殊功能，但主要功能就是对电压、电阻和电流进行测量，数字多用表，作为现代化的多用途电子测量仪器，主要用于物理、电气、电子等测量领域。
一般的数字万用表可以测量交、直流电压、交、直流电流、频率、电阻、电容、二极管、三极管等。
2.万用表的外观
3.数字万用表使用前的检查
1．首先检查万用表的外观、表笔的外观，看是否有破损；
2．检查表笔的好坏，把万用表打到通断档，表笔插在相应的孔里，并短接，看是否显示通，若通正常，否则表笔没插好或表笔损坏；
3．检查表笔位置是否正确。
4.基本的测量操作
◆注意:在测试电阻、电容、通断和二极管之前，需断开电路电源并
给所有的高压电容放电。
◆发出蜂鸣声代表通
注意：首先要强调的是用数字万用表测量二极管时，实测的是二极管的正向电压值，如果被测二极管开路或极性接反，显示屏将显示"OL";当测量在线二极管时，测量前必须断开电源，并将相关的电容放电。
◆注意：当开路对地电势大于1000V时，请勿测量电路内电流；当
引线插在电流孔时，请勿把测试表笔与电路或元件并联。
◆测量交直流电流时首先断开电路，将数字万用表串入电路，在未
知测量电流大小的情况下，直接用Auto自动挡，如果显示屏上显示为0L，则表明量程太小，需重新选定量程。
5.使用时的注意事项
1．测量电压时，检查表笔位置，千万不要把表笔插在测量电流的孔里，容易短路，烧坏表或出现其他安全事故，一定要把表笔放到所要测量电压的两个点上，电压为并联测量；
2．测量电流时，一定要串入回路，表笔也要插入相应的插口中，这样才能测到电流，测量完后把表笔放回测量电压孔；
3．为避免因读数错误而导致触电或伤害，显示电池低电量时应尽快更换电池；
4．对测量交流电30V以上、直流电60V以上时，应格外小心，防止触电事故；
5．测量时应正确使用接线端、开关档位和量程；
6．测量电阻、通断性、二极管或电容器以前，应切断电路电源，并把所有的电容器放电；
7．仪表有手动（Range）和自动(Auto)两种量程：开机时数字万用表自动进入(Auto)自动量程，仪表会根据被测量值的大小，由大到小自动判断，选择合适的量程，但测量时较长；也可以通过按“Range”键，手动选择量程，测量时间短，精度高；
8．交流电压无正负之分，测量时应注意人身安全，不要随便用手触摸表笔的金属部分；
9．最好断电测量，若需带电测量，务必注意安全！。
