Cia lub multimeter ua lub luag haujlwm ntau dua hauv kev saib xyuas
1. Ua kom pom tseeb ntawm kev ua haujlwm sib txawv thaum tsis quav ntsej qhov sib txuam ntawm cov khoom siv
Qee cov neeg siv tau them nyiaj ntau dua rau ntau hom kev ua haujlwm multimeter thaum yuav khoom, tab sis lawv nyiam tsis quav ntsej qhov sib txuam ntawm cov khoom siv. Yog tias tsis muaj cov khoom siv tsim nyog, qhov sib txawv ntawm kev ua haujlwm tsis tuaj yeem ua tiav lawm. Piv txwv li, qee cov neeg siv cia siab tias qhov yuav khoom multimeter tuaj yeem kuaj xyuas qhov pib tam sim no thiab kuaj xyuas qhov kub thiab txias nyob rau hauv ntau yam mob, tab sis lawv tsis yuav tshwj xeeb tam sim no clamps thiab ntsuas kub ntsuas. Yog tias koj xav muab kev ua si tag nrho rau kev ua haujlwm ntawm lub tsheb multimeter, qhov sib txuam ntawm qee cov khoom siv tseem ceeb heev. Qee yam ntawm cov khoom siv no yog qhov tsim nyog, thiab ntau dua yog txuam nrog kev ua haujlwm ntawm lub tsheb multimeter.
Cov khoom siv hauv lub tsheb multimeter feem ntau muaj xws li cov hauv qab no: inductive pick-up, roj teeb alligator clip, tshwj xeeb kuaj clip rau SMD thaj Cheebtsam (siv los ntsuas qhov tsis kam xws li SMD resistance, capacitance, inductance thiab transistors, uas tuaj yeem ua haujlwm nrog ib qho. tes, ua Kev Ntsuas yog yooj yim dua), tam sim no sensors, siab probes, torque probes thiab IC probes, thiab lwm yam. Cov khoom siv no feem ntau tsis siv hauv kev saib xyuas. Rau cov tuam txhab kev saib xyuas, thaum yuav cov khoom siv, lawv yuav tsum xav txog ntau yam xws li cov neeg siv khoom zoo, kev saib xyuas lub tuam txhab nyiaj txiag, thiab kev siv txhua hnub, txhawm rau xaiv qhov tsim nyog thiaj li ua tiav kev siv cov khoom siv siab tshaj plaws.
2. Muab cov cuab yeej siv zoo vim muaj kev cuam tshuam cov lus yooj yim
Qee cov neeg siv xav yuav high-end imported tsheb multimeters, tab sis thaum lawv pom tias cov lus interface yog lus Askiv, lawv yooj yim muab cov khoom lag luam nrog ntau cov haujlwm tiav lossis cov khoom siv high-end. Qhov tseeb, qhov no tsis tsim nyog. Cov haujlwm yooj yim ntawm ntau yam multimeters zoo sib xws, thiab ntau lub luag haujlwm raug cim nrog cov cim sib txawv, yog li nws tsis nyuaj rau siv. Ntev npaum li koj mus dhau txoj kev kawm yooj yim, koj tuaj yeem ceev cov kev siv.
Multimeters feem ntau tsis ua haujlwm, tab sis ntau lub luag haujlwm tsis tas siv hauv kev saib xyuas.
1. "Tso rau qhov txhaws" rau qee qhov haujlwm
Qee tus neeg ua haujlwm saib xyuas feem ntau ntshai siv multimeter vim lawv txhawj xeeb txog kev puas tsuaj rau cov khoom siv thaum lub sijhawm kuaj, qhov pom tseeb tshaj plaws yog qhov kev sim tam sim no. Txoj kev ntsuas tam sim no tsis nyuaj, xws li qhov pib tam sim no, thawj zaug thiab theem nrab tam sim no ntawm lub tshuab hluav taws xob hluav taws xob, thiab qhov kev sim tam sim no ntawm cov roj injector, muaj ntau qhov yuam kev tuaj yeem pom los ua lub hauv paus rau kev kuaj mob, tab sis cov kws kho mob tsis tshua siv nws. hauv kev saib xyuas. Nws tau nkag siab tias ntau tus kws kho mob ntshai siv qhov kev sim tam sim no vim tias lawv ntshai ntawm "hluav taws kub" lossis ua rau cov khoom puas hauv kev sim vim qhov kev xeem tsis raug. Qhov tseeb, ntau lub multimeters tau tsim nrog cov khoom siv tshwj xeeb hauv Circuit Court lossis cov cuab yeej tiv thaiv kev tiv thaiv txhawm rau tiv thaiv kev sib xyaw ua ke. Piv txwv li, ib qho ntxiv DY2201 multimeter txais cov cuab yeej tiv thaiv kev ntsuas tam sim no txhawm rau tiv thaiv kev siv tsis raug. Tsuas yog thaum kev ntsuas tam sim no raug xaiv, qhov sib txuas "mA" lossis "20A" jack yuav qhib. Txwv tsis pub, nws yuav raug thaiv los ntawm baffle, uas tuaj yeem ua tau zoo kom tsis txhob tso cov kev xeem tsis raug. Cov neeg ua haujlwm saib xyuas tuaj yeem ua siab tawv siv qhov ntsuas tam sim no, tab sis yuav tsum ua haujlwm raws li kev siv.
2. Tsis txaus hais txog qhov ua yuam kev hauv kev sim
Txhua lub cuab yeej yuav muaj qhov yuam kev hauv kev ntsuas, tab sis qhov yuam kev yuav tsum raug txo qis hauv kev ntsuas kom tsis txhob muaj kev ua haujlwm yuam kev kom ntseeg tau qhov tseeb ntawm qhov ntsuas ntsuas. Qhov yuam kev loj uas feem ntau tshwm sim hauv kev siv multimeters yog qee zaum tshwm sim los ntawm cov cuab yeej, thiab qee zaum tshwm sim los ntawm qee yam tib neeg. Ob yam nram qab no yuav tsum tau nyiam cov neeg ua haujlwm saib xyuas: ①Vim qhov tseeb thiab kev daws teeb meem ntawm multimeter tsis txaus, yog tias qhov kev txiav txim tsuas yog raws li kev kwv yees, feem ntau yuav ua rau tib neeg yuam kev. ②Vim txoj kev sim sib txawv ntawm ntau yam multimeters, multimeters yuav muaj lawv tus kheej ntsuas qhov yuam kev hauv cov teeb liab sib txawv. Yog li ntawd, thaum siv multimeters, cov neeg ua haujlwm tu yuav tsum sim siv cov cuab yeej nrog cov qib siab precision, thiab tib lub sijhawm ua raws li cov txheej txheem ua haujlwm nruj me ntsis. txo qhov yuam kev.
