A digital voltmeter (DVM) ntsuas qhov tsis paub cov tswv yim hluav taws xob los ntawm converting cov hluav taws xob rau a digital tus nqi thiab ces qhia cov hluav taws xob nyob rau hauv tus lej. DVMs feem ntau yog tsim los ntawm ib hom tshwj xeeb ntawm analog-rau- digital converter hu ua integrating converter.
Ib yam li ib tug yuav nug, ua li cas cov voltmeter ua haujlwm?
Ua haujlwm Txoj cai ntawm Digital Voltmeter . yog nyob li cas digital voltmeter ua haujlwm : Tsis paub voltage teeb liab yog pub rau lub tshuab hluav taws xob mem tes uas tsim cov mem tes uas nws qhov dav yog proportional rau lub teeb liab input. Cov zis ntawm lub tshuab hluav taws xob mem tes yog pub rau ib ceg ntawm AND rooj vag.
Ib tug kuj yuav nug, voltmeter ntsuas voltage li cas? A voltmeter ntsuas yog instrumental ntsuas qhov sib txawv ntawm hluav taws xob muaj peev xwm ntawm ob lub ntsiab lus hauv ib qho hluav taws xob hluav taws xob. Ib qho analog voltmeter ntsuas txav tus pointer hla ib qho kev faib ua feem rau lub voj voog hluav taws xob ; ib digital voltmeter ntsuas muab tus lej tso saib.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog digital voltmeter?
Voltmeter yog ib qho kev ntsuas hluav taws xob siv los ntsuas qhov sib txawv ntawm ob lub ntsiab lus. Cov voltmeters digital tso saib tus nqi ntawm AC los yog DC voltage raug ntsuas ncaj qha raws li tus lej tsis sib xws es tsis txhob ntawm tus taw tes deflection ntawm qhov ntsuas tsis tu ncua xws li hauv cov twj paj nruag analog.
Dab tsi yog qhov zoo ntawm digital voltmeter?
Qhov zoo ntawm Digital Voltmeter Digital zaub ntawm cov zis tshem tawm tib neeg kev nyeem ntawv yuam kev. Kev nyeem ntawv yog qhov tseeb thiab nrawm piv rau cov ntsuas analog. Digital Voltmeter yog ruaj khov thiab txhim khu kev qha.

Yuav ua li cas koj xaim hluav taws xob tiv thaiv hluav taws xob?
Ntxig txhua lub xaim rau hauv lub qhov tsim nyog hauv qhov chaw txais khoom tshiab thiab ceev cov ntsia hlau davhlau ya nyob twg kom ruaj ntseg. Qhwv qhov kawg ntawm cov tooj liab liab lossis ntsuab xaim (hauv av) nyob ib ncig ntawm cov ntsia hlau ntsuab thiab nruj. Maj mam thawb lub qhov hluav taws xob rov qab rau hauv lub thawv thiab ceev cov ntsia hlau mounting
Dab tsi ua rau lub qhov hluav taws xob muaj hluav taws xob tsawg?
Ib qho laj thawj uas lub qhov hluav taws xob yuav muaj lowvoltageis uas nws hnav tawm. Cov hluav taws xob hluav taws xob tuaj yeem hnav tawm tib yam li txhua yam khoom siv lossis cov khoom siv hluav taws xob.Qhov txuas tsis tu ncua thiab tshem tawm cov hlua rau hauv lub qhov hluav taws xob tuaj yeem loosen thiab hnav cov kev sib txuas
Yuav ua li cas koj xaim lub tshuab hluav taws xob mus rau qhov ntsuas hluav taws xob?
Muaj peb cov xov hlau uas yuav tsum tau txuas mus rau qhov tseeb regulator davhlau ya nyob twg. Weld lub regulator mount rau lub tsheb laij teb ncej. Txuas lub regulator rau lub mount. Txuas lub roj teeb zoo cable hlau - feem ntau yog liab - rau tus tswj. Polarize lub generator los yog alternator los ntawm tus regulator
Koj siv lub ntsuas hluav taws xob ntsuas hluav taws xob li cas?
Txhawm rau siv lub ntsuas hluav taws xob, kov ib qho kev sojntsuam rau ib lub xaim lossis kev sib txuas thiab lwm qhov kev sojntsuam mus rau qhov sib txawv ntawm cov xaim lossis kev sib txuas
Puas yog txhua lub tshuab hluav taws xob muaj GFCI qhov hluav taws xob?
Duplex (ob chav) qhov hluav taws xob muaj nyob rau ntawm lub tshuab hluav taws xob nqa tau thiab txhua qhov khoom siv 120 volts. Hauv av txhaum kev tiv thaiv qhov hluav taws xob (GFCI) yog qhov tshwj xeeb ntawm qee cov qauv thiab tiv thaiv tus neeg siv los ntawm hluav taws xob shocks
