Siv lub multimeter txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau
Cov huab cua los nag thiab huab cua yog maj mam nce ntxiv, thiab muaj ntau cov lus ceeb toom ua txhaum rau qhov ua rau cov dej xau. Kuv ntseeg hais tias cov phooj ywg hluav taws xob tau siv ntau lub hlwb los nrhiav qhov ua rau kom tawg. Qhov tseeb, tus kws tshaj lij hluav taws xob qhia rau koj tias koj tuaj yeem yooj yim paub qhov ua rau ntawm cov dej xau nrog lub tshuab hluav taws xob hauv koj txhais tes.
Kev tshawb nrhiav qhov tseeb:
Ua ntej txheeb xyuas qhov chaw xau tshwm sim, peb yuav tsum xub saib qhov tshwm sim txhaum cai thiab pom tseeb hauv tsev; thib ob, saib seb puas muaj cov ntsiab lus tsis txaus ntseeg los ntawm qhov chaw, thiab tom qab ntawd mus rau qib tom ntej ntawm kev tshuaj xyuas.
1. Ua ntej disconnect lub ntsiab kev rho tawm ntawm peb cov kab hluav taws xob nkag, thiab tua tag nrho cov neeg siv khoom hluav taws xob, xws li tshem tawm lub tub yees, disconnecting lub twj tso kua mis hloov, thiab lwm yam.
2. Muab cov iav ntawm cov digital multimeter rau ntawm 200M iav ntawm ohm ntau yam, tso ib qho kev xeem coj mus rau ib qho ntawm ob lub qhov hluav taws xob ntawm qhov chaw thauj khoom, thiab lwm qhov kev sim coj kov cov phab ntsa, nyiam dua hauv av xaim lossis ib ntus hauv av xaim. . Tom qab tus lej tso tawm ntawm lub multimeter yog qhov ruaj khov, qhov ntsuas hluav taws xob tiv thaiv tus nqi ntawm cov kab tseem ceeb tau nyeem tawm.
Yog tias tus nqi hluav taws xob tiv thaiv qis dua {{0}}.5 megohm, ces muaj teeb meem nrog cov kab tseem ceeb. Yog hais tias lub rwb thaiv tsev tsis kam siab tshaj 0.5 megohm, nws tuaj yeem txiav txim siab tias muaj teeb meem nrog cov kab tseem ceeb. Siv tib txoj kev los ntsuas lwm cov hlau, thiab tseem xyuas cov nqi kom pom tias muaj teeb meem nrog cov kab loj.
3. Tshawb xyuas cov nqi hluav taws xob tiv thaiv ntawm shunt thiab txhua yam khoom siv hluav taws xob, thiab xyuas ib qho los ntawm ib qho tib yam kom txog thaum pom qhov txhaum.
Kev ceev faj ua haujlwm:
1. Thaum siv 200M block ntawm ohm block ntawm multimeter, yuav tsum ceev faj tsis txhob kov cov hlau ntawm cov hlau lead nrog koj txhais tes thaum ntsuas, txwv tsis pub kev nyeem ntawv yuav tsis raug.
2. Thaum ntsuas txhua yam khoom siv hluav taws xob, ua tib zoo tso tawm ua ntej kom tsis txhob muaj qhov hluav taws xob tam sim no hauv cov khoom siv hluav taws xob los ntawm kev ua phem rau tib neeg.
Txoj kev no yog ib txoj hauv kev zoo los nrhiav qhov txhaum hauv lub xeev tsis muaj hluav taws xob. Txoj kev no kuj tseem siv tau rau cov neeg siv hluav taws xob thiab lub tsev tsim hluav taws xob tshawb nrhiav, tab sis thaum tshawb nrhiav, tsis yog tsuas yog cov khoom siv hluav taws xob yuav tsum raug txiav, tab sis kuj tseem yuav tsum tau txiav cov kab nruab nrab kom tsis txhob muaj hluav taws xob poob.
