5 lub ntsiab siv rau clamp ammeters
Feem ntau thaum ntsuas tam sim no nrog ib qho ammeter zoo tib yam, lub ammeter yuav tsum tau txuas nrog rau hauv lub voj voog rau kev ntsuas tom qab lub tshuab hluav taws xob raug kaw. Qhov no yog teeb meem heev, thiab qee zaus cov kev khiav hauj lwm ib txwm tsis tso cai rau qhov no. Lub sijhawm no, nws yooj yim dua los siv lub clamp ammeter. Lub clamp ammeter tuaj yeem ntsuas qhov tam sim no yam tsis tau txiav tawm hauv Circuit Court. Tsuas yog clamp cov hlau ntawm qhov tam sim no ntsuas hauv lub puab tsaig. Txawm li cas los xij, qhov tseeb ntawm clamp meters feem ntau tsis siab, feem ntau yog qib 2.5 txog qib 5, thiab feem ntau yog txwv rau siv thaum qhov hluav taws xob ntawm cov kab hauv qab ntsuas tsis tshaj 500V.
Muaj ntau ntau hom thiab hom ntawm clamp ammeters. Piv txwv li, T-301 clamp ammeter tsuas yog siv los ntsuas AC tam sim no, thaum T-302 clamp ammeter tuaj yeem ntsuas AC tam sim no thiab AC voltage. Lub MG24 hnab tshos clamp ammeter Ammeters kuj tuaj yeem ntsuas AC tam sim no thiab AC voltage; kuj tseem muaj MG21 thiab MG22 AC thiab DC clamp ammeters, thiab lwm yam. Thaum ua kev ntsuas, ntau hom clamp ammeters yuav tsum raug xaiv raws li cov khoom sib txawv raug ntsuas. Yog tias koj tsuas ntsuas AC tam sim no, koj tuaj yeem xaiv T-301 clamp ammeter. Yog tias siv lwm hom clamp ammeters, qhov hloov pauv yuav tsum tau txav mus rau qhov xav tau raws li qhov khoom ntsuas.
Raws li kev nyeem ntawv hom, clamp ammeters suav nrog ob pawg: hom pointer thiab hom digital; Raws li qhov hluav taws xob Circuit Court, muaj qhov tsawg-voltage clamp meters thiab high-voltage clamp meters; Raws li kev ua haujlwm, clamp ammeters suav nrog AC clamp meters zoo tib yam, AC clamp meters DC dual-purpose clamp meter, to tam sim no clamp meter, clamp meter nrog multimeter, thiab lwm yam. Cov tsos ntawm clamp meters txawv heev.
Ib qho yooj yim clamp meters tsuas yog siv los ntsuas AC tam sim no thiab ntsuas tsis tau lwm yam hluav taws xob tsis zoo. Lub clamp 'meter' nrog multimeter muaj nuj nqi ntxiv kev ua haujlwm ntawm multimeter ntawm lub hauv paus ntawm lub ntsuas ntsuas. Nws txoj kev siv yog tib yam li multimeter.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub ntsuas ntsuas digital yog qhov tseem ceeb tib yam li cov ntsuas ntsuas ntsuas analog. Qhov txawv yog tias lub vijtsam LCD siv los tso saib cov txiaj ntsig digital. Qhov loj tshaj plaws yog tias tsis muaj kev nyeem ntawv yuam kev, qhov ntsuas tau tuaj yeem nco tau, thiab koj tuaj yeem ntsuas ua ntej thiab tom qab ntawd nyeem.
