Cov micro-ohmmeter feem ntau yog siv los ntsuas ntau yam resistances me me, xws li: DC winding tsis kam ntawm ntau lub motors thiab transformers, cable tsis kam thiab tiv tau tiv thaiv ntawm cov keyboards thiab lub qhov hu.
1. Qhib lub hwj huam tseem ceeb, lub teeb taw qhia lub zog yuav ua rau.
2. Xaiv cov ntawv xeem iav, feem ntau yog 50 milliohms rau kev tiv thaiv kev tiv thaiv kev sib tw.
3. Luv luv-ob txoj kev sib tw ua rau pom tias tus pointer rov qab xoom. Yog tias tus taw qhia taw tes rau xoom lub sijhawm no, kev sim hauv qab no tuaj yeem ua. Yog tias tus taw qhia tsis taw tes rau xoom lub sijhawm no, koj yuav tsum kho lub pob qhov xa rov qab kom txog thaum tus pointer rov qab xoom.
4. Tso ob txoj kev ntsuas coj mus kom ze rau ntawm ob qhov kawg ntawm cov khoom yuav tau sim, thiab nyeem cov ntaub ntawv los ntawm lub xov tooj tom qab tus pointer ruaj khov (tus xov tooj ntawm sab laug thiab sab xis tsis dhau 2), thiab sau cov ntsiab lus tawm hauv kev nthuav dav.
5. Yog tias lub hom phiaj xeem tsis tas yuav muaj nuj nqis tshwj xeeb, tab sis tsuas yog yuav tsum txiav txim siab seb nws puas tau raws li cov khoom lag luam tshwj xeeb, koj tuaj yeem xaiv" kuaj / teeb tsa" hloov raws li lub chaw teeb tsa ua ntej xeem, thiab kho" kev teeb tsa kev hloov kho" pob qhov rooj rau qhov khoom lag luam tus nqi (Piv txwv, 20 milliohms), ua qhov kev xeem raws li qib 4. Lub sijhawm no, yog tias cov khoom tsim nyog, micro-ohm meter" lub teeb ci" lub teeb yuav nyob rau, txwv tsis pub" tsis ua haujlwm" lub teeb yuav tsum muaj.
6. Tom qab ntsuas tiav, cov khoom yuav tsum raug tshem tawm thiab lub zog tseem ceeb ntawm lub micro-ohm meter yuav tsum muab tua.
