style="text-indent:25px">數(shù)字式萬用表由于內(nèi)部結(jié)構(gòu)多用集成電路所以過載能力較差，損壞后一般也不易修復(fù)。數(shù)字式萬用表輸出電壓較低（通常不超過1伏）。對(duì)于一些電壓特性特殊的元件的測(cè)試不便（如可控硅、發(fā)光二極管等）。指針式萬用表輸出電壓較高。電流也大，可以方便的測(cè)試可控硅、發(fā)光二極管等。對(duì)于初學(xué)者應(yīng)當(dāng)使用指針式萬用表，對(duì)于非初學(xué)者應(yīng)當(dāng)使用兩種儀表。數(shù)字式萬用表內(nèi)部采用了多種振蕩，放大、分頻保護(hù)等電路，所以功能較多。比如可以測(cè)量溫度、頻率（在一個(gè)較低的范圍）、電容、電感，做信號(hào)發(fā)生器等等。</p><p style="text-indent:25px">選用原則1、指針表讀取精度較差，但指針擺動(dòng)的過程比較直觀，其擺動(dòng)速度幅度有時(shí)也能比較客觀地反映了被測(cè)量的大?。ū热鐪y(cè)電視機(jī)數(shù)據(jù)總線(SDL)在傳送數(shù)據(jù)時(shí)的輕微抖動(dòng)）；數(shù)字表讀數(shù)直觀，但數(shù)字變化的過程看起來很雜亂，不太容易觀看。2、指針表內(nèi)一般有兩塊電池，一塊低電壓的1.5V,一塊是高電壓的9V或15V,其黑表筆相對(duì)紅表筆來說是正端。數(shù)字表則常用一塊6V或9V的電池。在電阻檔，指針表的表筆輸出電流相對(duì)數(shù)字表來說要大很多，用R×1Ω檔可以使揚(yáng)聲器發(fā)出響亮的“噠”聲，用R×10kΩ檔甚至可以點(diǎn)亮發(fā)光二極管(LED)。3、在電壓檔，指針表內(nèi)阻相對(duì)數(shù)字表來說比較小，測(cè)量精度相比較差。某些高電壓微電流的場(chǎng)合甚至無法測(cè)準(zhǔn)，因?yàn)槠鋬?nèi)阻會(huì)對(duì)被測(cè)電路造成影響（比如在測(cè)電視機(jī)顯像管的加速級(jí)電壓時(shí)測(cè)量值會(huì)比實(shí)際值低很多）。數(shù)字表電壓檔的內(nèi)阻很大，至少在兆歐級(jí)，對(duì)被測(cè)電路影響很小。但極高的輸出阻抗使其易受感應(yīng)電壓的影響，在一些電磁干擾比較強(qiáng)的場(chǎng)合測(cè)出的數(shù)據(jù)可能是虛的。4、總之，在相對(duì)來說大電流高電壓的模擬電路測(cè)量中適用指針表，比如電視機(jī)、音響功放。在低電壓小電流的數(shù)字電路測(cè)量中適用數(shù)字表，比如BP機(jī)、手機(jī)等。手持式數(shù)字萬用表測(cè)電阻原理。</p><div
