Taw qhia rau Yuav Ua Li Cas Xaiv Xaiv Lub Computer Hluav Taws Xob Hluav Taws Xob uas siv tus multimeter
Xaiv lub plawv ruaj khov - Yuav ua li cas siv ntau multatative xaiv computer lub zog? Tam sim no, lub cim tshiab ntawm cov npav duab, suab phaib, nyuaj tsav thiab lwm yam khoom siv tsis tau roj av {}}}}}}}}}}}}}} heev nyob rau hauv cov nqe lus ntawm kev siv fais fab. Koj puas tau xav txog kev muab nws lub siab muaj zog thaum koj muaj cov khoom siv uas koj nyiam hlub thoob plaws koj lub taub hau.
Muaj ntau cov lus sib tham ntawm cov kev txheeb xyuas cov peev txheej ntawm cov ntawv xov xwm thiab ntawv xov xwm thiab cov ntawv xov xwm, uas tuaj yeem ua tau teev ua peb lub ntsiab:
Ua tibzoo saib -}} Tshawb xyuas yog tias cov ntaub ntawv siv rau cov ntaub ntawv fais fab tau zoo, yog tias tus qauv ua haujlwm zoo, thiab yog tias qhov teeb tsa yog qhov tsim nyog. Yuav kom ncaj ncees, txoj kev npaj no yog ib qho nyuaj rau lwm tus. Firstly, nws yuav tsum tau cov kev paub hauv cov khoom hluav taws xob; Thib ob, txhawm rau txhawm rau ua kom huv tsib caug lub plab thiab rau lub ntsws ntawm lub zog siv, nws yog qhov tsim nyog los tshem tawm cov khoom siv fais fab, uas invernably tsoo lub khw muag khoom ntawm cov tub luam. Thaum lub foob tau tawg, tus tub lag luam tawm tsam tau ploj, thiab txawm tias muaj teeb meem nrog lub zog hluav taws xob, DIY yog qhov tsim nyog. Kuv xav tias ntau cov rookies dog dig raug yuam kom ua cov cw loj hauv qhov teeb meem uas tsis muaj kev vam meej.
Thib ob kov - hais txog kev kov seb puas muaj cua tshuab kub tawm los ntawm lub zog hluav taws xob yog kub thiab puas yog npog yog qhov kov tau rau ib lub sijhawm.
Peb tsw tsw - tus ntxhiab tsw vim lub zog hluav taws xob ua rau muaj ntxhiab tsw tawg tom qab ua haujlwm ntev. Lub tom kawg ob yog purely kev sib txuam ntawm kev paub zoo, yuav ua li cas tuaj yeem txiav txim siab tsis muaj kev paub dhau los? Ntawm no, Kuv pom zoo ib txoj hauv kev siv ntau ntau ntxiv los txiav txim siab qhov zoo ntawm cov khoom siv fais fab, uas yuav muab qee qhov kev pab rau cov pib tshiab.
Firstly, ntawm chav kawm, nws yog ib qho tsim nyog los nrhiav ntau ntau (nyiam dua cov digital ib qho) thiab siv tau nws. Qhov hluav taws xob muab los ntawm ATX lub zog fais fab tshwj xeeb suav nrog 3.3V, 5.0V, thiab 12.0v. Ntawm lawv, 12.0v yog lub zog tseem ceeb rau cov khoom siv kho vajtse, thiab kev hloov pauv kuj tseem ceeb tom qab sib txuas ntxiv. Yog li ntawd, tom qab txuas tag nrho cov khoom siv ntawm lub khoos phis tawm, nthuav tawm cov kev sojntsuam dub thiab cov kev sojntsuam liab rau hauv lub 12V tso tawm volfage). Tom qab txuas tag nrho cov txuas, koj tuaj yeem pib lub tshuab rau kev sim. Tom qab booting tuaj, peb tuaj yeem pom tias cov ntaub ntawv ntau sib xws yog hloov tas li kom txog thaum lub kaw lus tau pib thiab tso tseg. Sau cia tus nqi hluav taws xob valve nyob rau lub sijhawm no. Feem ntau, nws yuav tsum nyob ib ncig ntawm 12v (kwv yees li ntawm 11.95V thiab 12.15V. Yog tias nws tseem tsis tau muaj peev xwm loj heev, nws yuav ua rau lub peev xwm loj heev, nws yuav ua rau lub cuab yeej loj heev.
