Kuv yuav tsum qhib dab tsi thaum siv lub multimeter los kuaj xyuas qhov xau?
1. Ua ntej disconnect lub ntsiab cais hloov ntawm lub hwj chim nkag thiab tua tag nrho cov neeg siv hluav taws xob loads, xws li unplugging lub tub yees, tig tawm lub twj tso kua mis hloov, thiab lwm yam.
2. Muab lub tshuab ntsuas digital tso rau ntawm 200M ohm ntau yam, tso ib qho kev xeem coj mus rau ib qho ntawm ob lub qhov hluav taws xob nyob ntawm qhov chaw thauj khoom, thiab kov lwm qhov kev sim ua rau ntawm phab ntsa. Nws yog qhov zoo tshaj plaws los kov cov av xaim lossis ib qho av xaim ib ntus. Tom qab tus naj npawb tso tawm ntawm lub multimeter stabilizes, nyeem dab tsi yog qhov kev tiv thaiv hluav taws xob ntawm cov kab tseem ceeb. Yog tias tus nqi rwb thaiv tsev tsis zoo tsawg dua 0.5 megohms, ces muaj teeb meem nrog cov kab tseem ceeb. Yog hais tias lub rwb thaiv tsev tsis kam yog siab tshaj 0.5 megohms, 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 xyuas cov nqi kom pom tias muaj teeb meem nrog cov kab loj.
3. Tshawb xyuas cov nqi hluav taws xob tiv thaiv hluav taws xob ntawm cov ceg hluav taws xob thiab txhua yam khoom siv hluav taws xob, thiab siv tib txoj kev los xyuas lawv ib qho los ntawm ib qho kom txog thaum pom qhov txhaum.
Yuav ua li cas txheeb xyuas cov dej xau nrog multimeter:
1. Ua ntej disconnect lub ntsiab kev rho tawm ntawm tus neeg siv lub zog nkag, thiab tua tag nrho cov neeg siv cov khoom hluav taws xob, xws li tshem tawm lub tub yees, tua lub twj tso kua mis hloov, thiab lwm yam.
2. Muab cov digital multimeter rau ntawm 200M ohm ntau yam, tso ib qho kev xeem coj mus rau ib qho ntawm ob lub qhov hluav taws xob nyob ntawm qhov chaw thauj khoom, thiab kov lwm qhov kev sim coj mus rau phab ntsa, nyiam dua rau hauv av xaim lossis ib ntus hauv av xaim. Tos rau lub multimeter
Tom qab tus lej tso tawm yog qhov ruaj khov, qhov nyeem tau yog qhov ntsuas hluav taws xob tiv thaiv tus nqi ntawm cov kab tseem ceeb. Yog tias tus nqi hluav taws xob tiv thaiv qis dua {{0}}.5 megohms, ces muaj teeb meem nrog cov kab tseem ceeb. Yog hais tias lub rwb thaiv tsev tsis kam siab tshaj 0.5 megohms, ces txoj kab tseem ceeb yuav raug txiav tawm. Ib yam dab tsi mus tsis ncaj ncees lawm. Siv tib txoj kev los ntsuas lwm cov hlau thiab xyuas cov nqi kom pom tias muaj teeb meem nrog cov kab loj.
3. Tshawb xyuas qhov kev tiv thaiv kev tiv thaiv hluav taws xob ntawm cov ceg hluav taws xob thiab txhua yam khoom siv hluav taws xob, thiab siv tib txoj kev los xyuas lawv ib qho los ntawm ib qho kom txog thaum pom qhov txhaum.
