QHIA TXOG KEV PAB CUAM RAU DC FAIS FAIS COV NTAUB NTAWV VASTAGE
1. Potentiometer kev hloov kho
Ntau cov khoom siv fais fab tau nruab nrog potentiometers rau kev kho cov zis hluav taws xob. Thaum kho lub laujkaub, tig nws maj mam thiab saib cov kev hloov pauv ntawm voltmeter mus txog rau cov nqi voltage tau mus txog.
2. Kev tswj digital
Qee cov ntaub ntawv siab tshaj DC muaj cov tswj hwm digital muaj zog, uas tuaj yeem hloov kho cov zis hluav taws xob hauv ntej vaj huam sib luag. Txoj kev no tuaj yeem muab cov kev tswj kom meej thiab yooj yim dua los nyeem cov nuj nqis ua lej.
3. Sab nraud tswj cov cim
Qee cov khoom siv hluav taws xob tuaj yeem hloov kho cov zis hluav taws xob sab nraud xws li cov hluav taws xob voltage lossis kev sib txuas lus digital. Qhov no tso cai rau kev sib koom ua ke ntawm cov khoom siv fais fab uas muaj cov tshuaj ntsuam xyuas lossis cov microcontrollers, ua rau muaj kev tswj hwm ntau dua.
4. Tswv yim kev hloov kho
Nyob rau hauv ib tug kaw - lub voj fais fab muab, cov zis voltage tau kho los ntawm lub voj pib. Yog tias cov zis voltage diffuntes los ntawm cov teeb tus nqi, lub tswv yim teeb liab yuav kho cov zis ntawm lub zog ntawm lub zog kom txog thaum lub tshuab hluav taws xob rov qab mus rau tus nqi. Kev kuaj xyuas thiab kho cov vaj lug kub qhia yog lwm txoj hauv kev kom ntseeg tau ntau cov kev ruaj khov.
5. Calibration
Yog tias cov zis hluav taws xob ntawm DC cov khoom siv hluav taws xob coj los ntawm cov teeb tus nqi, yuav tau ua calibration. Qhov no feem ntau cuam tshuam nrog kev kho cov hluav taws xob sab hauv kev siv hluav taws xob lossis siv cov khoom ntsuas hluav taws xob los hloov cov zis hluav taws xob.
6. Software hloov
Rau cov khoom siv hluav taws xob nrog software tswj ua haujlwm, cov zis voltage tuaj yeem hloov kho los ntawm software interface. Txoj kev no tuaj yeem muab kev hloov kho tau ntau dua thiab siv tshuab ua.
7. Kho kom haum
Muaj qee kis, nws yuav tsim nyog los kho cov khoom siv kho vajtse ntawm lub zog hluav taws xob, xws li hloov lub capacitors lossis kev hloov kho cov khoom ntawm cov Circuit Court Board. Qhov no feem ntau yuav tsum muaj kev txhawb nqa kev ua haujlwm thiab cov cuab yeej tsim nyog.
