Dab tsi yog tus qauv rau theem pov thawj ntawm peb -}} pa taws ncig siv cov khoom siv sib xyaw?
1. Xaiv cov iav raug: Ua ntej, xaiv ntau ntau rau ntawm AC Voltage ntsuas lub iav thiab xaiv ntsuas kom haum raws li hom Circuit Court.
2. Txuas cov phiaj xwm: Qhib cov Circuit Court thiab ntxig vertical ntsuas kev sim ua ntu zus ntawm ob qho kawg ntawm nws cov khoom siv fais fab.
3. FORE SAIB COV TSWV YIM: Tom qab ntsuas ntsuas tiav, saib xyuas kev nyeem ntawv ntawm multimeter. Yog tias qhov kev ntsuas hluav taws xob ntsuas tau ntsuas los ntawm ob qho kev sim muaj sib npaug thiab qhov zoo, nws qhia tau tias ob lub ntsiab lus no yog nyob rau tib lub peev xwm thiab hauv theem; Yog tias qhov ntsuas hluav taws xob muaj sib npaug tab sis tsis zoo, nws qhia tau tias theem yog rov qab; Yog tias cov hluav taws xob voltage tsis sib npaug, nws qhia tau tias muaj qhov sib txawv ntawm lawv, thiab theem kev sib raug zoo tsis tuaj yeem txiav txim siab ncaj qha.

Thaum siv malcimeter, kev ceev faj hauv qab no yuav tsum tau ua kom muaj kev nyab xeeb thiab ntsuas qhov tseeb:
1. Kev ua haujlwm nyab xeeb: thaum siv tshuaj puv, xyuam xim rau kev nyab xeeb thiab zam cov xwm txheej txaus ntshai xws li hluav taws xob hluav taws xob lossis luv luv. Tshwj xeeb tshaj yog thaum ntsuas cov hluav taws xob ntau lossis qib siab tam sim no, yuav tsum ceev faj ntxiv.
2. Xaiv cov iav uas tsim nyog: ua ntej ntsuas, kwv yees qhov loj ntawm cov hluav taws xob hluav taws xob kom raug ntsuas, thiab tom qab ntawd xaiv cov iav uas tsim nyog. Yog tias cov iav xaiv tsis tsim nyog, nws yuav ua rau cov kev ntsuas ntsuas tsis raug thiab muaj kev puas tsuaj rau kev sib tw.
3. Ua tib zoo mloog rau qhov ntsuas ntau: Thaum ntsuas hluav taws xob, tam sim no, lossis kev ntsuas tus nqi yog nyob rau hauv qhov ntsuas tau ntawm cov multimatatimeter. Yog tias nws ntau tshaj qhov ntsuas tau ntau, nws yuav ua rau kev puas tsuaj rau kev ntsuas ntau lossis tsis raug.
4. Tswj kev sib cuag zoo: thaum ntsuas kev ntsuas, xyuas kom tus cwj mem tau sib cuag nrog lub Circuit Court lossis cov khoom siv raug sim kom tsis txhob qhia kev sib cuag lossis cov teeb meem tsis txaus.
5. Ua tib zoo saib xyuas ib puag ncig kev xeem: Thaum ib puag ncig kev sim, xyuas kom ib puag ncig ib puag ncig yog qhuav, muaj qhov cua, thiab txav mus los ntawm kev sib cuam tshuam sib cuam tshuam. Zam tsis txhob xeem nyob rau hauv damp, kub, lossis muaj zog sib nqus teb ib puag ncig kom tsis txhob cuam tshuam qhov tseeb ntawm cov txiaj ntsig ntawm kev xeem.
6. Ua raws cov txheej txheem kev ua haujlwm: Thaum siv cov txheej txheem sib xyaw, ua raws cov txheej txheem kev ua haujlwm thiab cov lus qhia, thiab tsis txhob cais lossis kho cov multimeter ntawm yuav. Yog tias koj tsis paub txog txoj kev ua haujlwm lossis muaj lus nug, nws raug nquahu kom nrhiav kev pab tshaj lij.
