Kev tiv thaiv yog ntsuas qhov nyuaj ntawm cov khoom siv hluav taws xob muaj nyob hauv ntws los ntawm ib yam khoom tshwj xeeb. Nws zoo ib yam li kev sib txhuam ntawm cov khoom uas tau ntsib thaum txav lossis txav mus los ntawm qhov chaw. Kev tiv thaiv yog ntsuas hauv ohms; 1 ohm yog sib npaug rau 1 volt ntawm qhov hluav taws xob sib txawv rau 1 ampere ntawm tam sim no (1 volt/1 amp). Koj yuav pom koj qhov hluav taws xob sib txawv los ntawm kev nyeem ob peb zaug siv koj cov cuab yeej. Kev tiv thaiv tuaj yeem ntsuas nrog analog lossis digital multimeter lossis ohmmeter. Cov neeg nyeem analog feem ntau muaj rab koob uas yuav txheeb xyuas qhov ntsuas ntawm qhov ntsuas, thaum tus nyeem ntawv digital yuav muab tus lej nyeem.

Txoj Kev 1 ntawm 3: Ntsuas Kev Tiv Thaiv nrog Digital Multimeter
Kauj Ruam 1. Xaiv yam khoom uas nws xav tau los ntsuas
Rau qhov ntsuas tau raug tshaj plaws, ntsuas qhov tsis kam ntawm ib feem ntawm tus kheej. Tshem cov khoom tiv thaiv los ntawm Circuit lossis sim nws ua ntej koj nruab nws. Kuaj cov khoom siv thaum tseem nyob hauv Circuit tuaj yeem ua rau nyeem tsis raug los ntawm lwm cov khoom.
- Piv txwv li, koj tuaj yeem ntsuas qhov tsis kam ntawm cov hloov pauv, sib txuas lus sib txuas, lossis lub cev muaj zog.
- Yog tias koj tab tom sim ib lub Circuit Court lossis txawm tias tsuas yog tshem tawm ib feem, nco ntsoov tias txhua lub zog rau hauv Circuit Court raug kaw ua ntej mus.
Kauj Ruam 2. Ntsuas qhov ntsuas coj mus rau qhov ntsuas qhov tseeb
Ntawm ntau lub ntsuas ntsuas, ib qho kev xeem txhuas yuav dub thiab lwm qhov yuav liab. Ib lub multimeter feem ntau muaj ntau qhov ntsuas ntsuas, raws li seb nws puas tau siv los ntsuas qhov tsis kam, qhov hluav taws xob, lossis amperage (tam sim no). Feem ntau txoj cai nyob rau qhov ntsuas kom tsis kam raug sau lo lus "COM" (rau ib qho) thiab ib daim ntawv lo nrog cov ntawv Greek omega, Ω, uas yog lub cim rau "ohm".
Plug cov hlau lead dub rau hauv lub qhov (socket) sau tias "COM" thiab cov hlau lead liab rau hauv lub qhov ("ohm")
Kauj Ruam 3. Qhib lub multimeter thiab xaiv qhov ntsuas zoo tshaj plaws
Kev tiv thaiv ntawm ib feem tuaj yeem yog los ntawm ohms (1 ohm) txog megaohms (1, 000, 000 ohms). Txhawm rau kom tau txais qhov nyeem tau raug ntawm qhov tsis kam koj yuav tsum teeb tsa lub multimeter rau qhov tsim nyog rau koj cov khoom. Qee qhov digital multimeter yuav txiav qhov ntau rau koj, tab sis lwm tus yuav xav tau teeb tsa tus kheej. Yog tias koj muaj lub tswv yim dav dav ntawm qhov kev tawm tsam tsuas yog teeb tsa nws mus rau qhov ntawd. Yog tias koj tsis paub meej, koj tuaj yeem txiav txim siab qhov ntau los ntawm kev sim thiab ua yuam kev.
- Yog tias koj tsis paub qhov ntau, pib nrog qhov nruab nrab nruab nrab teeb tsa, feem ntau yog 20 kilo-ohms (kΩ).
- Kov ib qho coj mus rau qhov kawg ntawm koj cov khoom thiab lwm qhov ua rau qhov kawg rov qab.
- Tus lej ntawm lub vijtsam yuav yog 0.00, OL, lossis tus nqi tiag tiag ntawm kev ua haujlwm.
- Yog tias tus nqi yog xoom, qhov ntau tau teeb tsa siab dhau thiab yuav tsum tau txo qis.
- Yog tias lub vijtsam nyeem OL (ntau dhau) qhov ntau tau teeb tsa qis dhau thiab xav tau nce ntxiv mus rau qhov siab tshaj tom ntej. Kuaj qhov kev tivthaiv dua nrog kev teeb tsa ntau yam tshiab.
- Yog tias lub vijtsam nyeem tus lej tshwj xeeb xws li 58, qhov ntawd yog tus nqi ntawm tus tiv thaiv. Nco ntsoov coj mus rau hauv tus account qhov ntau tau thov. Ntawm lub digital multimeter lub kaum sab xis sab xis yuav tsum ceeb toom koj ntawm koj qhov chaw teeb tsa. Yog tias nws muaj kΩ ntawm lub ces kaum, qhov kev tiv thaiv tiag tiag yog 58 kΩ (58, 000 ohms).
- Thaum koj tau txais hauv qhov raug, sim txo qhov ntau ib zaug ntxiv los saib seb koj puas tuaj yeem nyeem tau qhov tseeb dua. Siv qhov ntsuas qis tshaj plaws rau qhov nyeem tau raug qhov tseeb tshaj plaws.
Kauj Ruam 4. Kov lub multimeter coj mus rau qhov kawg ntawm cov khoom koj tab tom sim
Ib yam li koj tau ua thaum koj tau teeb tsa qhov ntau, kov ib qho coj mus rau ib qho kawg ntawm cov khoom siv thiab lwm qhov ua rau qhov kawg rov qab. Tos kom txog thaum tus lej nres nce lossis nqis thiab sau tus lej ntawd. Qhov no yog qhov tsis kam ntawm koj tivthaiv.
Piv txwv li, yog tias koj nyeem ntawv yog.6 thiab kaum sab xis hais MΩ qhov kev tiv thaiv ntawm koj cov khoom yog 0.6 mega-ohms
Kauj Ruam 5. Tua lub multimeter
Thaum koj ua tiav ntsuas tag nrho koj cov khoom siv, tua lub multimeter thiab tshem tawm cov hlau lead rau khaws cia. Cov qhab nia
