Tus txheej txheem ua hauj lwm ntawm digital voltage tester yog raws li analog {0}- Digital Conversion Technology. Nws hloov lub ntsuas hluav taws xob rau hauv lub qhov hluav taws xob ntsuas hluav taws xob ntawm lub ntsej muag, uas yog tom qab ntawd hloov mus rau cov zis digital los ntawm ib qho kev hloov kho digital}} digital converter (ADC). Lub microprocessor cov ntaub ntawv cov ntaub ntawv los ntawm ADC, xws li lim thiab suav, thiab thaum kawg nthuav tawm cov ntaub ntawv ua tiav rau cov neeg siv los ntawm cov zaub interface. Cov kev ua haujlwm no ua rau nws tau meej dua thiab yooj yim dua los nyeem dua li cov analog voltmeters.
Hauv cov nqe lus ntawm hom, digital vertage kuaj muaj ntau yam sib txawv thiab ntau yam. Portable digital digmeters yog yooj yim rau nqa thiab haum rau kev ntsuas ntawm cov chaw ntsuas hluav taws xob, xws li cov tshuab hluav taws xob siv cov kev ua yuam kev thaum xav tau; desktop digital voltmeters muaj qhov siab ntsuas thiab siv feem ntau siv nyob rau hauv cov chaw kuaj kom tau raws li cov kev xav tau siab rau high {precision ntsuas; Thaum lub sijhawm digital voltmeters nyob rau hauv cov tshuab ntsuas xyuas cov khoom siv ua ke ua ke, ua lub luag haujlwm ntawm cov khoom siv hluav taws xob, tso cai rau kev ntsuas hluav taws xob thiab cov hluav taws xob ntsuas.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov teb, digital voltmeters yog ubiquitous. Hauv kev ua teb hluav taws xob engineering, cov kws tshawb nrhiav siv lawv los sim cov voltage ntawm ntau cov nodes nyob rau hauv ib qho nodes nyob rau hauv ib qho nodes hauv ib qho kev siv hluav taws xob, kom muaj kev ruaj ntseg ntawm Circuit Designs. Ntawm cov khoom hluav taws xob cov khoom lag luam, lawv kuj tau siv los tshawb xyuas yog tias cov khoom ntsuas hluav taws xob ntawm cov khoom ua tau raws cov qauv. Hauv kev tswj hwm kev lag luam, lawv tuaj yeem saib cov khoom siv hluav taws xob ntawm cov cuab yeej muaj nyob hauv tiag- lub sij hawm los xyuas kom meej kev ua haujlwm ib txwm ua. Yog hais tias tus voltage mus txawv txav, lawv tuaj yeem muab cov khoom muaj qee qhov pom tseeb kom tiv thaiv cov cuab yeej siv puas.
Hauv kev tshawb fawb tshawb fawb uas yuav tsum tau ntsuas hluav taws xob ua tau, cov kws tshawb fawb digital, muab cov kws tshawb nrhiav tau hais txog cov ntaub ntawv raug. Nyob rau hauv cov neeg peg xeem neeg ua haujlwm, nrog cov chaw muaj koob npe ntawm cov tsev ntse, Portable voltage kuaj tau siv los xyuas tsev neeg hluav taws xob, kom muaj kev nyab xeeb hluav taws xob hauv tsev. Lawv cov zaub mov xa tuaj txhua xyoo ntxiv mus ntxiv, tsim ib qho kev lag luam zoo nkauj.
Tam sim no, cov ntsuas digital voltage ntsuas ntsuas kev lag luam tab tom qhia txoj kev loj hlob zoo. Kev lag luam nplai tseem nthuav dav, tau txiaj ntsig los ntawm kev nrawm ntawm cov kev hloov pauv hluav taws xob tshiab, thiab ua kom muaj kev xav tau kev siv tshuab. Nws cia siab tias yuav tau nce mus ntxiv rau ntawm qhov nruab nrab txhua xyoo kev sib xyaw ua ke hauv lub neej yav tom ntej. Nyob rau hauv cov nqe lus ntawm kev txhim kho thev naus laus zis, kev txawj ntse thiab kev sib txuas nrog cov peev xwm hloov chaw, nrog rau kev hloov pauv ntawm huab cia thiab saib xyuas cov chaw deb.
