Ib digitalclamp meteryog ib qho hluav taws xob tester uas sib txuas lub voltmeter thiab clamp ammeter. Zoo li lub multimeter, lubclamp meterkuj tau dhau los ua cov txheej txheem digital los ntawm yav dhau los analog mus rau niaj hnub no.
Covclamp meterFeem ntau yog tsim los ntawm electromagnetic ammeter thiab nkag mus rau tam sim no transformer. Nws yog ib qho cuab yeej siv tau yooj yim uas tuaj yeem ntsuas qhov hloov pauv tam sim no ntawm lub voj voog yam tsis muaj kev cuam tshuam lub voj voog. Nws yog ib qho yooj yim heev rau siv hauv kev kho hluav taws xob thiab nws yog dav siv.
Covclamp meterAmeslikas siv los ntsuas AC tam sim no. Niaj hnub no, multimeter muaj tag nrho cov haujlwm uas nws siv tau los ntsuas AC thiab DC voltage, tam sim no, tsis kam, capacitance, kub, zaus, diode, thiab txuas ntxiv.
1. Raws li xav tau, xaiv A-(AC) lossis A-(DC) cov ntaub ntawv.
2. Nias lub trigger kom clamp lub clamp meter lub taub hau rau hauv cov hlau tam sim no los kuaj thiab tuav nws hauv nruab nrab ntawm lub taub hau clamp.
3, thaum ntsuas tam sim no me me, nws qhov kev nyeem ntawv tsis pom tseeb, koj tuaj yeem sim cov xaim nyob ib ncig ntawm ob peb lub lem, tus naj npawb ntawm tig los ua tus lej ntawm lub puab tsaig, tom qab ntawv nyeem {{1} } ntsuas tus nqi / tus lej hloov.
4. Thaum lub sij hawm ntsuas, tus neeg xyuas pib nyob rau hauv kev sim yuav tsum muab tso rau hauv nruab nrab ntawm lub puab tsaig thiab kaw lub puab tsaig kom txo tau qhov yuam kev.
Nco tseg
(1) Qhov voltage ntawm Circuit Court nyob rau hauv kev ntsuam xyuas yog qis dua qhov ntsuas hluav taws xob ntawm lub ntsuas hluav taws xob.
(2) Thaum ntsuas qhov tam sim no ntawm cov kab hluav taws xob high-voltage, hnav cov hnab looj tes insulating, hnav cov khau insulated, thiab sawv ntawm lub rwb thaiv tsev lev.
(3) Lub puab tsaig yuav tsum raug kaw kom nruj yam tsis muaj kev hloov pauv.
(4) Rau phau ntawv qhia ntau yam clamp meter, yog tias koj tsis paub qhov ntsuas tam sim no, koj yuav tsum tau teeb tsa rau qhov siab tshaj plaws thiab maj mam txo nws.
