Kev ua tau zoo ntsuas rau multimeters
1. Teb ceev
Teb ceev yog cuam tshuam nrog AD hloov dua siab tshiab nti nyob rau hauv lub multimeter. Feem ntau ntawm cov digital multimeter tau txais ob daim ntawv tseem ceeb ntawm AD hloov dua siab tshiab nti, txawm hais tias nws qhov tseeb tuaj yeem ncav cuag 4 ½, tab sis vim tias muaj cov txheej txheem sib xws, yog li cov lus teb ceev tsis txaus siab heev. Thaum kuaj tsis kam, peb xav tias qee qhov multimeters qhia qhov tseem ceeb ceev ceev, thaum qee qhov tseem ceeb yuav tsum tau tos ntev heev los tawm. Tsis tas li ntawd, thaum ntsuas qhov ntsuas hluav taws xob, yog tias qhov hluav taws xob hloov pauv, cov lus teb ceev ceev ntawm multimeter yuav tuaj yeem cuam tshuam.
2. Kev ntsuas qhov tseeb
Peb feem ntau hnov 3 1/2 (3 1/2) los yog 4 1/2 (4 1/2) ntawm lub multimeter, hais qhov tseeb ntawm lub multimeter. " 1/ 2 tus lej" yog tus lej uas tsuas tuaj yeem pom 1 lossis tsis tau.
Piv txwv li: "Peb thiab ob tus lej" (tseem hu ua "peb thiab ib nrab tus lej") tuaj yeem tso saib 000~1999.
Tus "3/4 tus lej" yog tus lej uas tuaj yeem pom cov lej 1, 2 thiab 3, tab sis tsis yog lwm tus lej.
Piv txwv li: "Plaub thiab peb-quarter tus lej" tuaj yeem tso saib 0000~39999.
Thaum xaiv ib lub multimeter, koj tuaj yeem xaiv qhov precision raws li qhov xav tau tiag tiag, siab precision, tus nqi kuj tseem kim.
3. Muaj nuj nqi
Multimeter muaj nuj nqi ua tiav, ntxiv rau kev sim ntau yam ntawm qhov voltage, tam sim no, tus nqi tiv thaiv, tab sis kuj tuaj yeem hloov pauv ntau yam, ntsuas pulse zaus, capacitance, saib xyuas qhov siab tshaj plaws thiab qhov tsawg kawg nkaus ntawm qhov voltage thiab tam sim no, kub, thiab lwm yam. ..
4. Kev tiv thaiv kev nyab xeeb thiab ruaj khov
Multimeter muaj kev tiv thaiv zoo heev, nrog rau tam sim no, dhau-voltage, tus cwj mem tso rau hauv qhov kev ceeb toom tsis raug (xws li ntsuas qhov ntsuas hluav taws xob, tus cwj mem yuav muab tso rau hauv qhov ntsuas tam sim no) thiab lwm yam. Zoo multimeter casing ruaj, zoo dua, tshwj xeeb tshaj yog nyob rau hauv lub iav hloov, xav tias tshwj xeeb tshaj yog du, siv tau ntau xyoo, yuav tsis muaj kev sib cuag nrog cov iav. Zoo multimeter cwj mem kuj yog ruaj, yuav tsis yooj yim tawg, thiab jack tiv tauj teeb meem.
Hauv cov ntsiab lus, yog tias kev lag luam tso cai, muaj ib qho kev ua tau zoo ntawm multimeter, zoo li yuav ib tus poj niam zoo nkauj thiab tsim txiaj, lub neej ntawm inexhaustible.
