Lub ntsuas hluav taws xob digital yog lub ntsuas hluav taws xob uas tuaj yeem ntsuas AC tam sim no ntawm lub voj voog los ntawm kev txuas txuas txuas mus ntxiv. Vim yog qhov yooj yim siv thiab txav tau yooj yim ntawm cov digital clamp meter, nws yog dav siv nyob rau hauv lub overhaul thiab overhaul ntawm ib co circuits. Qhov chaw ua haujlwm ntawm lub ntsuas ntsuas digital yog tsim los ntawm electromagnetic ammeter thiab pub-los ntawm tam sim no. Tom ntej no, cia peb saib seb lub ntsuas hluav taws xob digital yog dab tsi thiab qee qhov kev siv thiab kev nyeem ntawv.
Dab tsi yog digital clamp meter?
Lub clamp meter kuj tseem hu ua clamp meter, uas yog ib qho cuab yeej uas tuaj yeem clamp cov hlau thiab ua kom pom tam sim no yam tsis tau txiav cov hlau. Lub digital clamp meter tuaj yeem ntsuas qhov tam sim no ntawm cov xaim tsuas yog los ntawm clamping lub sheath ntawm cov hlau, uas ua rau kev ua haujlwm yooj yim dua thiab nyab xeeb dua.
Yuav ua li cas siv digital clamp meter thiab teeb meem xav tau kev saib xyuas
Yuav siv cov digital clamp meter li cas:
1. Ua ntej ntsuas, ua txhua yam xoom hloov kho;
2. Tom ntej no, koj yuav tsum xaiv cov khoom tsim nyog, raws li lub hauv paus ntsiab lus ntawm kev xaiv ntau yam loj ua ntej thiab tom qab ntawd ib qho me me, lossis koj tuaj yeem kwv yees nws raws li lub npe ntawm tus nqi ntawm cov khoom siv hluav taws xob;
3. Thaum siv qhov tsawg kawg nkaus rau kev ntsuas, kev nyeem ntawv yuav tsis pom tseeb. Lub sijhawm no, cov hlau yuav tsum tau ntsuas yuav tsum raug mob ob peb lub lem, thiab tus naj npawb ntawm cov lem yuav tsum yog raws li tus naj npawb ntawm lem nyob rau hauv nruab nrab ntawm lub puab tsaig. Nyob rau hauv cov ntaub ntawv no Qhov kev nyeem ntawv yog: nyeem=qhia tus nqi × ntau / tag nrho sib txawv × tus naj npawb ntawm lem;
4. Thaum ntsuas, cov hlau yuav tsum ntsuas yuav tsum nyob hauv nruab nrab ntawm lub puab tsaig, thiab lub puab tsaig yuav tsum tau kaw kom nruj, uas tuaj yeem txo qhov yuam kev;
5. Thaum kev ntsuas tiav, hloov qhov hloov pauv mus rau qhov siab tshaj plaws.
Kev ceev faj rau kev siv cov digital clamp meters:
1. Qhov voltage ntawm txoj kab yuav tsum ntsuas yuav tsum yog qhov ntsuas hluav taws xob ntawm tus tsov ntxhuav clamp meter;
2. Thaum ntsuas qhov tam sim no ntawm cov kab hluav taws xob siab, nco ntsoov hnav cov hnab looj tes insulating, insulating khau thiab sawv ntawm cov ntaub qhwv insulating kom muaj kev nyab xeeb;
3. Lub puab tsaig ntawm lub digital clamp meter yuav tsum raug kaw kom nruj, thiab kev ntsuas tsis tuaj yeem ua raws li qhov xwm txheej ntawm hluav taws xob.
Digital Clamp Meter Nyeem Ntawv
Lub clamp meter tau muab faib ua ob hom: koob hom thiab hom digital. Piv nrog rau rab koob hom clamp meter, txoj kev nyeem ntawv ntawm digital clamp meter yog qhov yooj yim heev. Koj tsuas yog yuav tsum siv txoj kev ntsuas kom raug los ntsuas thiab tos rau cov duab digital. Tom qab tus lej ruaj khov, koj tuaj yeem nyeem tau.
Cov digital clamp meter tuaj yeem siv dav hauv qee qhov kev lag luam thiab qee lub neej. Nws tuaj yeem siv tsis tau tsuas yog rau kev kho dua tshiab ntawm qee lub voj voog, tab sis kuj tseem siv tau rau kev kho dua tshiab ntawm qee cov khoom siv hluav taws xob. Nws yog ib qho cuab yeej siv. Piv nrog rau qee qhov ntsuas ntsuas tam sim no, cov ntsuas ntsuas digital tsis tsuas yog muaj cov yam ntxwv ntawm kev siv yooj yim thiab kev ua haujlwm yooj yim, tab sis kuj muaj cov yam ntxwv ntawm kev nyab xeeb, ceev thiab txav tau yooj yim. Cov cuab yeej no feem ntau siv nyob rau hauv lub neej niaj hnub, thiab nws cov yam ntxwv yooj yim nqa nqa nqa tau yooj yim rau peb lub neej. Paub txog kev siv qee qhov digital clamp meters thiab qee txoj kev nyeem ntawv tuaj yeem pab koj siv nws zoo dua.
