Txhawm rau tiv thaiv kev puas tsuaj rau multimeter, thov nco ntsoov ceev faj hauv qab no:
1. Feem ntau, kev puas tsuaj rau digital multimeter yog tshwm sim los ntawm kev ntsuas iav yuam kev. Piv txwv li, thaum ntsuas AC lub zog, yog tias lub ntsuas ntsuas tau teeb tsa rau cov iav tiv thaiv, thaum qhov kev sojntsuam tiv tauj lub zog, nws tuaj yeem ua rau muaj kev puas tsuaj rau cov khoom sab hauv ntawm multimeter. Yog li ntawd, ua ntej siv ib tug multimeter rau kev ntsuas, nws yog ib qhov tsim nyog los xyuas seb lub ntsuas ntsuas yog qhov tseeb. Tom qab siv, tso qhov ntsuas kev ntsuas ntawm AC 750V lossis DC 1000V, yog li tsis muaj teeb meem dab tsi tsis raug ntsuas hauv kev ntsuas tom ntej, nws yuav tsis ua rau muaj kev puas tsuaj rau digital multimeter.
2. Qee qhov digital multimeters puas vim qhov ntsuas voltage thiab tam sim no tshaj qhov ntau Yog tias ntsuas lub zog hluav taws xob hauv 20V ntau, nws yooj yim ua rau muaj kev puas tsuaj rau AC amplifier circuit ntawm digital multimeter, ua rau lub multimeter poob nws qhov kev ntsuas AC. Thaum ntsuas qhov hluav taws xob DC, yog tias ntsuas qhov ntsuas hluav taws xob siab tshaj qhov ntsuas qhov ntsuas, nws tuaj yeem yooj yim ua rau lub ntsuas hluav taws xob tsis zoo hauv lub ntsuas. Thaum ntsuas tam sim no, yog tias tus nqi tam sim no tshaj qhov ntau, nws feem ntau tsuas yog ua rau lub fuse hauv multimeter hlawv tawm thiab yuav tsis ua rau muaj kev puas tsuaj. Yog li thaum ntsuas qhov ntsuas qhov ntsuas hluav taws xob, yog tias koj tsis paub qhov kwv yees ntawm qhov ntsuas qhov ntsuas hluav taws xob, koj yuav tsum xub teeb lub ntsuas ntsuas rau lub iav siab dua, ntsuas nws tus nqi, thiab tom qab ntawd hloov lub zog kom tau txais qhov tseeb dua. Yog hais tias tus nqi hluav taws xob yuav tsum ntsuas deb tshaj qhov siab tshaj plaws uas lub multimeter tuaj yeem ntsuas tau, qhov ntsuas qhov ntsuas siab yuav tsum tau muab cais.
3. Cov kev txwv sab saud ntawm feem ntau cov digital multimeters rau DC voltage yog 1000V, thiab qhov txwv sab saud rau AC voltage yog 750V. Yog li, qhov ntsuas qhov ntsuas hluav taws xob feem ntau yog qis dua qhov txwv siab tshaj ntawm multimeter thiab yuav tsis ua rau lub multimeter puas. Yog hais tias qhov ntau tshaj qhov txwv ntawm lub multimeter, nws yuav ua rau muaj kev puas tsuaj rau lub multimeter.
4. Tsis txhob ntsuas qhov hluav taws xob tam sim no, hom kev tiv thaiv, hom, thiab hom buzzer. Thaum lub sij hawm sim, qhov kev hloov pauv hloov pauv tsis tuaj yeem tig, tshwj xeeb tshaj yog nyob rau hauv high voltage thiab high tam sim no.
5. Yog hais tias siv ib tug multimeter resistor los xyuas qhov zoo ntawm cov khoom los yog ntsuas qhov kev tiv thaiv tus nqi ntawm cov khoom nyob rau hauv lub Circuit Court, nws tsis raug tso cai kom them nyob rau hauv lub Circuit Court vim hais tias lub multimeter resistor siv lub internal roj teeb ntawm lub multimeter ua hauj lwm. Yog tias lub Circuit Court raug them, nws yooj yim rau kev puas tsuaj rau lub roj teeb sab hauv ntawm lub multimeter thiab cuam tshuam qhov ntsuas qhov tseeb. Yog hais tias lub multimeter resistor yog nruab nrog ib tug fuse, nws kuj yog ib qho yooj yim rau kev puas tsuaj rau qhov sib npaug ntawm cov resistor,
6. Thaum lub cim roj teeb tshwm rau ntawm qhov screen, nws qhia tias lub roj teeb qis thiab yuav tsum tau hloov. Tom qab txhua qhov ntsuas, qhov ntsuas yuav tsum raug muab tua. Txawm hais tias siv lossis khaws cia, cov dej noo thiab dej nkag yog nruj me ntsis txwv.
