Kev ceev faj rau kev ntsuas DC tsis kam nrog multimeter
1. Kev xaiv ntau yam
Yog tias qhov ntau yam raug xaiv kom me me, cov zaub yuav tso tawm "1.", thiab ntau qhov loj yuav tsum tau siv rau lub sijhawm no; ntawm qhov tsis sib xws, yog tias qhov ntau yam raug xaiv kom loj, tus lej ze rau "0" yuav tshwm rau ntawm cov zaub, nyob rau lub sijhawm no, nws yuav tsum tau hloov pauv siv ntau yam me me.
2. Yuav nyeem li cas
Tus lej tso tawm ntawm cov zaub ntxiv rau chav tsev xaiv los ntawm lub zog sab sauv thiab qis yog nws qhov kev nyeem ntawv. Nws yuav tsum nco ntsoov tias chav tsev yog "Ω" hauv "200", chav tsev yog "KΩ" hauv "2K ~ 200K" thaiv, thiab chav tsev yog "MΩ" hauv "2M ~ 2000M" thaiv.
3. Yog tias qhov ntsuas qhov ntsuas tsis zoo tshaj qhov siab tshaj ntawm qhov kev xaiv, qhov ntau tshaj "1." yuav tso tawm kom pom, thiab yuav tsum xaiv ntau dua. Rau kev tawm tsam loj dua 1MΩ lossis siab dua, kev nyeem ntawv yuav ruaj khov tom qab ob peb feeb. yog li qub.
4. Thaum tsis zoo txuas, xws li qhib Circuit Court, lub 'meter' qhia "1."
5. Thaum kuaj xyuas qhov impedance ntawm kab nyob rau hauv kev sim, nco ntsoov tshem tawm tag nrho cov khoom siv fais fab hauv kab hauv qab kev sim thiab tso tawm tag nrho cov capacitors. Yog tias muaj cov khoom siv hluav taws xob thiab lub zog khaws cia hauv kab hauv qab kev sim, nws yuav cuam tshuam qhov tseeb ntawm kab impedance xeem.
6. Koj tuaj yeem kov qhov kev tawm tsam nrog koj txhais tes thaum ntsuas, tab sis tsis txhob kov ob qhov kawg ntawm qhov kev tawm tsam nrog koj txhais tes tib lub sijhawm - tib neeg lub cev yog tus neeg xyuas pib nrog lub zog loj, tab sis qhov kev tawm tsam yog txwv.
