Piav qhia luv luv txog kev ua haujlwm theem pib ntawm kev ntsuas kev cuam tshuam nrog kev sib txuam
Kev ua haujlwm theem pib ntawm ntau qhov kev sib txuam ua ntsuas ntsuas.
1, Thawj qhov txuas nrog tus cwj mem, kev xaiv ntawm kev xaiv tuaj yeem yog tus lej ntawm cov ntaub ntawv, tus cwj mem dub tau tso rau hauv lub davhlau ya nyob twg, kom ntseeg tau tias qhov kev sib tw yog qhov qub.
2, rotate the multimeter gear, measuring resistance should be used resistance gear, if you are not sure how much resistance value, you should first range switch, placed in the maximum value, and then by a large number of range to the small range gear to switch, so that the meter pointer indicates that more than 1/2 of the full scale can be. Tom qab xaiv cov ntaub ntawv tsim nyog tshaj plaws, ob lub npiv kov yog li tus pointer rau xoom kom ntseeg tau tias qhov ntsuas tau yog.
3, txuas ob ntu ntawm lub resistor, tus cwj mem yog txuas nrog casually, tsis muaj cov ntsiab lus zoo thiab tsis zoo, nco ntsoov tias qhov kev sib cuag yog qhov zoo.
4, nyeem cov ntaub ntawv tso tawm rau ntawm multimeter tsis tshwm sim, tej zaum yuav muaj qhov tsis zoo uas yog qhov tsis txaus, hloov cov ntau.
5, Nce cov ntau, yog tias tsis muaj cov ntaub ntawv, nws tsuas yog txhais tau tias lub resistor yog qhov tsis zoo. Yog tias muaj cov ntaub ntawv tso tawm cov ntaub ntawv, them sai sai kom ntxiv rau chav ntawm lub iav.
Tus txheej txheem tseem ceeb ntawm kev loj heev:
Yog kev siv ntawm rhiab magneto-hluav taws xob DC Ammeter (microampere meter) ua lub taub hau meter. Thaum ib qho me me tam sim no hla dhau lub taub hau, yog qhia tam sim no. Tab sis lub taub hau tsis tuaj yeem hla cov dej khov loj loj, yog li lub taub hau yuav tsum muaj kev sib txuas nrog cov deunt lossis voltage txo, yog li ntsuas qhov tam sim no, voltage thiab kev tawm tsam hauv Circuit Court.
Sau ntawv rau kev siv ntawm multimeter:
1, hauv kev siv cov roj sib xyaw ua ntej, yuav tsum xub ua thawj zaug ", uas tsis muaj hluav taws xob ntsuas hauv txoj haujlwm ntawm xoom voltage lossis xoom tam sim no.
2, thaum lub sijhawm ua kev siv compultimeter ntau, koj yuav tsum tsis txhob kov ib feem ntawm tus cwj mem nrog koj txhais tes, yog li kom ntseeg tau ntawm qhov ntsuas ntawm ib sab, thiab ua kom tus kheej kev nyab xeeb ntawm lwm txhais tes.
3, thaum ntsuas ib qho hluav taws xob tsawg, koj tsis tuaj yeem hloov cov iav tib lub sijhawm ntsuas, tshwj xeeb yog cov kev ntsuas siab tam sim no, koj yuav tsum them nyiaj ntau rau nws. Txwv tsis pub, pillimeter yuav raug rhuav tshem. Yog tias koj xav hloov lub zog, koj yuav tsum xub txiav tus cwj mem, hloov zog thiab tom qab ntawd rov qab mus rau qhov ntsuas.
4, ntau nplua mias siv, yuav tsum muab tso rau kab rov tav, yog li tsis ua rau ua yuam kev. Nyob rau tib lub sijhawm, nws kuj yuav tsum tau sau tseg kom tsis txhob muaj kev cuam tshuam ntawm sab nraud sib nqus teb ntawm cov multimeter.
5, Pultat Anchatus tau siv, yuav tsum muab tso rau hauv qhov siab tshaj plaws hloov AC Voltage iav. Yog tias nws tsis yog siv rau lub sijhawm ntev, lub roj teeb sab hauv pultingimeter yuav tsum tau tawm kom tsis txhob muaj roj teeb corrosion ntawm lwm cov khoom siv hauv lub ntsuas.
Kev txhawj xeeb
1, yog tias siv 2113 hluav taws xob sib xyaw ua ke, rau 5261 thawj lub iav 4102 me ntsis hloov kho rau ohms.
2, ua ntej siv los xyuas kom meej tias xyoo 1653 peb yuav ua rau lub ntsej muag liab thiab yog tias tus neeg taw tes tau tig los kho tus Paus Xoom Pob K, yog li ntawd tus pointer ntsiab lus rau xoomheej.
3, tus cwj mem liab ntxig rau hauv "Vω" lub qhov, tus cwj mem dub ntxig rau hauv "com" lub qhov, thiab tom qab ntawd raws li kev ntsuas ncig ua kom xaiv tau cov iav tsis tawm.
4, cov kwv yees kwv yees tus nqi, thawj tus neeg siv tau hloov kho tau ntawm cov iav loj tshaj plaws, yog tias tsis haum txaus, peb yuav tsum kho lub iav.
5, Qhov zoo tshaj plaws kev nyeem ntawv tsuas yog ob tug lej kaum xwb, hloov kho rau cov iav no tau nyeem tawm cov ntaub ntawv yog qhov tseeb tshaj plaws.
