Digital ohmmeter (lossis ohm meter) muaj txiaj ntsig zoo rau ntsuas kev tiv thaiv hluav taws xob hauv cov khoom siv hluav taws xob. Digital ohm meters yog qhov yooj yim dua los nyeem thiab siv dua li lawv cov analog analog. Cov duab loj loj yuav tsum qhia koj tus nqi tiv thaiv (tus lej, feem ntau ua raws tus lej lossis ob lossis ntau dua) thiab qhov ntsuas ntawm qhov ntsuas. Digital ohm meters sib txawv me ntsis los ntawm tus qauv rau tus qauv, yog li sab laj koj tus neeg siv phau ntawv qhia kom ntseeg tau tias koj nyeem nws raug.
Cov kauj ruam
Txoj Kev 1 ntawm 3: Nyeem Digital Display
Kauj Ruam 1. Txheeb xyuas qhov ntsuas ntawm kev nyeem los ntawm kev nrhiav "K" lossis "M" ib sab ntawm omega
Lub cim omega ntawm koj lub vijtsam digital ohmmeter qhia txog qib ohm. Txawm li cas los xij, yog qhov tsis kam ntawm txhua yam koj tab tom sim yog hauv kilo-ohm (1, 000 ohms) lossis mega-ohm (1, 000, 000 ohms) ntau, cov zaub yuav ntxiv "K" lossis "M," feem, nyob rau hauv pem hauv ntej ntawm lub cim omega.
Piv txwv li, nyeem ntawv uas hais tias 4.3 nrog tsuas yog lub cim omega qhia 4.3 ohms. Kev nyeem ntawv uas hais tias 4.3 nrog "K" ua ntej lub cim omega txhais tau tias 4.3 kilo-ohms (4, 300 ohms)
Kauj Ruam 2. Nyeem tus nqi tsis kam
Sib nrug los ntawm kev nkag siab txog qhov ntsuas ntawm digital ohmmeter, nkag siab qhov ua haujlwm tsis txaus yog lub hauv paus tseem ceeb ntawm txheej txheem nyeem ntawv ohmmeter. Cov lej feem ntau yog pem hauv ntej thiab nruab nrab hauv cov duab digital, thiab feem ntau nthuav mus rau ib lossis ob lub ntsiab lus sib tw.
- Kev tiv thaiv yog ntsuas ntsuas ntau npaum li cas cov cuab yeej lossis cov khoom siv txo qhov hluav taws xob uas ntws los ntawm nws. Cov lej ntau dua qhia txog qhov ntsuas kev tiv thaiv siab dua, uas txhais tau tias yuav tsum muaj lub zog ntau ntxiv los ua ke cov khoom siv hauv Circuit Court.
- Thaum koj ntsuas tus tiv thaiv, lub ntsuas hluav taws xob, lossis lwm yam khoom siv hluav taws xob, ohmmeter yuav tso tus lej qhia tias nws tiv taus.
Kauj Ruam 3. Nrhiav “1,” “OL,” (“hla lub voj”) lossis ob peb kab sib txuas rau qhov qhia tias qhov ntau tau teeb tsa qis dhau
Yog tias koj tsis siv lub ntsuas 'meter' nrog qhov pib ua haujlwm, koj yuav tsum teeb tsa koj tus kheej. Txhawm rau zam qhov teeb tsa qis dhau, ib txwm pib ntawm qhov siab tshaj plaws tau thiab ua haujlwm koj txoj hauv kev mus rau qis qis kom txog thaum ohmmeter sau npe nyeem ntawv. Ua qhov no txawm tias thaum koj paub ntau yam ntawm cov khoom koj tab tom sim.
Txoj Kev 2 ntawm 3: Siv Lub Tshuab Ntsuas
Kauj Ruam 1. Qhib lub ntsuas cua
Cov txheej txheem uas koj tig koj lub ohmmeter ntawm yuav txawv nyob ntawm tus qauv koj tab tom siv. Feem ntau, koj tuaj yeem tsuas yog ntiv tes xoo hloov qhov hais tias "Lub Hwj Chim" lossis "On/Off."
Tham nrog cov chaw tsim khoom kom paub ntau ntxiv txog yuav ua li cas xaiv qhov ua haujlwm tsis kam ntawm koj lub multimeter
Kauj Ruam 2. Xaiv qhov tsis kam ua haujlwm yog tias koj siv lub multimeter
Lub ohmmeter suav nrog hauv cov cuab yeej muaj nyob hauv multimeter, cov cuab yeej uas tseem ua haujlwm zoo li ammeter thiab voltmeter. Txoj hauv kev tseeb uas koj xaiv qhov kev ua haujlwm tsis sib xws yuav txawv me ntsis nyob ntawm tus qauv ntawm multimeter koj tab tom siv. Saib rau qhov hloov pauv lossis hu kom hloov chaw.
Tham nrog cov chaw tsim khoom kom paub ntau ntxiv txog yuav ua li cas xaiv qhov ua haujlwm tsis kam ntawm koj lub multimeter
Kauj Ruam 3. Kuaj qhov kev tiv thaiv hauv Circuit Court thaum nws tsis muaj zog
Hauv lwm lo lus, tsis txhob txuas lub Circuit Court mus rau lub zog siv thaum siv koj lub ohmmeter. Ua li ntawd tuaj yeem ua rau koj puas ohmmeter digital lossis ua rau koj nyeem tsis raug.
Kauj Ruam 4. Nqa cov khoom ib leeg tawm ntawm Circuit Court ua ntej ntsuas lawv
Yog tias koj xav ntsuas qhov kev tiv thaiv ntawm ib tus neeg tivthaiv (piv txwv li, vim tias koj xav tias nws ua tsis raug), tshem nws tawm ntawm Circuit Court, tom qab ntawv sim cov khoom tiv thaiv los ntawm kev kov cov coj mus rau ob tus ncej ntawm cov khoom. Qhov no yuav muab rau koj nyeem hauv paus tawm tsam uas koj tuaj yeem sim tom qab ntsuas qhov Circuit.
Txoj hauv kev tseeb uas koj tshem tawm cov khoom ib tus neeg nyob ntawm seb cov khoom siv yog dab tsi. Piv txwv li, yog tias koj tab tom ntsuas lub ntsuas hluav taws xob, koj yuav tsum tau tshem nws nrog cov hlau txuas thiab tso tawm cov hluav taws xob uas tseem tshuav los ntawm nws
Kauj Ruam 5. Kuaj qhov tsis kam ntawm cov khoom siv hluav taws xob siv cov ntsuas coj
Thaum koj npaj txhij los ntsuas cov khoom siv rau kev nyeem tsis taus, kov qhov kev xeem ua rau kev coj ua ntawm cov khoom siv. Cov kev coj ua no feem ntau tshwm sim raws li ob txoj kab xaim nyiaj xaim poking tawm ntawm cov khoom siv.
- Txawm tias nyob hauv tib hom kev tivthaiv, qhov tso rau ntawm cov khoom no sib txawv. Piv txwv li, hauv qee lub capacitors, cov coj ob leeg tawm ntawm tib sab. Hauv lwm lub tshuab hluav taws xob, ib tus hlau lead yuav tsoo tawm ntawm ib qho kawg thaum cov hlau lead thib ob nthuav tawm qhov kawg.
- Yog tias koj muaj teeb meem txheeb xyuas cov coj ntawm cov khoom koj xav tau hauv kev sim, sab laj cov chaw tsim khoom.
- Nws tsis muaj teeb meem twg cov tshuaj txhuas thiab cov khoom uas coj koj kov ua ke.
Txoj Kev 3 ntawm 3: Teem Ntau Yam
Kauj Ruam 1. Siv qhov pib-ntau qhov chaw yog ua tau
Feem ntau cov digital ohmmeters muaj qhov pib-ua haujlwm uas tshem tawm qhov xav tau rau koj los txheeb xyuas qhov raug. Qhov no txuag sijhawm thiab lub zog, thiab ua rau koj pib siv koj lub ohmmeter sai dua.
Qhov pib ntau qhov chaw tuaj yeem tsim kho, lossis koj yuav xav tau xaiv nws los ntawm cov ntawv qhia zaub mov. Tham nrog koj tus neeg siv phau ntawv qhia kom paub ntau ntxiv
Kauj Ruam 2. Pib ntawm qhov siab tshaj plaws ntawm koj lub ohmmeter
Ib txwm teeb tsa qhov ntau rau qhov siab tshaj plaws muaj thaum koj xub pib ntsuas seb koj puas tuaj yeem tau txais kev nyeem ntawv raug. Tuav tus sojntsuam ntawm ohmmeter tiv thaiv ob sab ntawm Circuit Court kom coj koj nyeem. Yog tias qhov ntau yog siab dhau, tom qab ntawv nyeem yuav nyob ntawm 0 lossis ze rau nws.
Yog tias koj teeb tsa qhov sib piv ntawm ohmmeter qhov qis heev, nws yuav ua rau rab koob nrawm nrawm mus rau ib sab, uas yuav ua rau nws puas tsuaj
Kauj Ruam 3. Tig qhov ntau ntawm ohmmeter 1 kauj ruam ntawm ib lub sijhawm los ntsuas qhov Circuit Court
Yog tias qhov ntau yog siab dhau rau hauv Circuit Court, kev nyeem ntawv yuav tsis raug lossis nws yuav nyuaj rau pom. Siv cov khawm hloov pauv ntau ntawm lub ntsuas ntsuas digital lossis tig lub xov tooj qis dua ntawm lub ntsuas ntsuas sib piv kom txo qis los ntawm 1 qib. Kuaj cov kev sojntsuam ntawm cov vojvoog dua kom pom tias koj nyeem tau meej dua. Yog tsis yog, khaws kho lub ntsuas qis dua kom txog thaum koj tuaj yeem pom cov ntawv nyeem.
