Kev ceev faj ua ntej siv Professional multimeter Digital
1. Before measuring, check whether the red and black test pens are connected correctly. The red test lead is connected to the red terminal or the jack marked with " plus ", and the black test lead is connected to the black terminal or the jack marked "-". The head part is damaged.
2. Ua ntej txuas qhov kev xeem coj mus rau lub voj voog nyob rau hauv kev sim, nco ntsoov xyuas seb cov iav uas tau xaiv puas zoo ib yam li cov khoom ntsuas. Txwv tsis pub, kev siv tsis raug ntawm cov iav thiab ntau yam yuav tsis tsuas tau txais cov txiaj ntsig kev ntsuas, tab sis kuj ua rau lub multimeter puas. Cov pib tshiab tau ceeb toom tias qhov kev puas tsuaj ntawm multimeter feem ntau tshwm sim los ntawm cov laj thawj saum toj no.
3. Thaum ntsuas, khaws koj cov ntiv tes kom deb ntawm cov hlau qhov chaw ntawm qhov kev xeem coj thiab cov khoom nyob rau hauv kev sim.
4. Yog tias qhov ntsuas qhov ntsuas yuav tsum tau hloov pauv, nws yuav tsum tau ua tom qab qhov kev ntsuam xyuas cov hlau lead tawm hauv Circuit Court, txwv tsis pub lub arc generated los ntawm kev sib hloov ntawm lub selector hloov yuav yooj yim hlawv tawm cov neeg ntawm lub selector hloov, ua rau muaj kev huam yuaj. ntawm kev sib cuag tsis zoo.
5. Hauv kev ntsuas qhov tseeb, feem ntau yuav tsum ntsuas ntau yam hluav taws xob ntau. Ua ntej txhua qhov kev ntsuas, ua tib zoo saib rau kev hloov pauv tus xaiv hloov mus rau qhov sib thooj iav thiab ntau yam raws li txhua txoj haujlwm ntsuas.
6. Tom qab kev ntsuas ua tiav, qhov hloov pauv yuav tsum tau muab tso rau hauv qhov siab tshaj plaws ntawm AC voltage.
