Puas yog multimeter nrog lossis tsis muaj clamp zoo dua?
Dedicated tam sim no clamp meter ntawm kev tshawb pom ntawm kab tam sim no thiab siab raug, txawm tias ib qho kev ua haujlwm tab sis txaus kom tau raws li kab tam sim no nrhiav pom. Tsuas saib, clamp tam sim no ntsuas yog tsim los ntawm tam sim no transformer thiab ammeter. Kev ntsuas cov txheej txheem hloov lub zog, yuav tsum tau muab tshem tawm los ntawm kev ntsuas cov hlau los hloov cov iav. Vim hais tias nyob rau hauv lub iav hloov yuav ua rau lub thib ob sab ntawm lub tam sim no transformer instantaneous qhib Circuit Court, yog hais tias lub ntsuas tam sim no loj, lub thib ob sab ntawm lub tam sim no transformer yuav tsim instantaneous high voltage, lub clamp meter yuav hlawv tawm.
Clamp meter yog pib siv los ntsuas AC tam sim no ntsuas yog khiav kab tam sim no qhov ntsuas ntsuas. Raws li koj tuaj yeem pom, qhov tam sim no tuaj yeem kuaj pom yam tsis muaj qhov cuam tshuam rau lub zog hluav taws xob, thiab nws yog tshwj xeeb hauv kev kuaj xyuas cov AC siab. Niaj hnub no lub clamp-on meters yog tsis mono-functional; Lawv muaj tag nrho cov haujlwm uas lub multimeter muaj, tab sis lawv kuj muaj tib lub zog.
Yog li ntawd, txhua tus muaj nws tus kheej zoo, yog hais tias koj xav mus ntes cov tam sim no ntawm lub Circuit Court yog khiav yeej clamp tam sim no meter yog zoo siv, tsis txhob disconnect tus kab ncaj qha rau tam sim no nrhiav tau. Nrog ib tug multimeter tab sis kuj disconnect tus kab los ntsuas, yog hais tias cov khoom nyob rau hauv lub nruam ntau lawm txheej txheem yuav tsis tau arbitrarily disconnected, lub sij hawm no lub multimeter tsis zoo.
Tam sim no lub clamp meter tau ntev tsis tau kaum xyoo dhau los lub clamp meter, nws siv Hall induction txoj cai, tsis tsuas yog ntsuas AC Circuit Court, DC tam sim no; Muab tso rau hauv tus cwj mem rau hauv digital multimeter, koj tuaj yeem ntsuas qhov voltage, tsis kam, capacitance, zaus thiab lwm yam. Raws li qhov tseeb, thiab digital multimeter yog tib yam, tsis muaj qhov sib txawv.
Lawv txawv
Yog tias koj yuav tsum tau hais tias ib qho ntawm cov clamp meter thiab multimeter yog qhov zoo rau siv, lawv cov kev paub hauv cov txheej txheem ntawm kev siv lawv tseem txawv me ntsis.
1. Clamp meter nws tuaj yeem ntsuas qhov tam sim no tas li, uas tsis tuaj yeem ua nrog multimeter. Yog tias koj xav tau ntsuas AC thiab DC tam sim no, nws raug nquahu kom yuav lub ntsuas ntsuas clamp; Tsis tas yuav ntsuas tam sim no ntawm kev yuav khoom ntawm multimeter.
2. Txhawm rau ntsuas qhov tam sim no tsis muaj lub zog, lub ntsuas hluav taws xob yuav tsum muaj lub puab tsaig, yog li nws lub cev lub cev yog qhov ntev. Vim tias tsis muaj lub bracket nyob rau sab nraum qab ntawm lub ntsuas ntsuas, kuv xav tias lub ntsuas ntsuas clamp yog ntau inclined los tuav ntawm tes ntawm kev ntsuas; multimeter muaj ib tug bracket nyob rau sab nraum qab ntawm qhov ntau inclined rau muab tso rau ntawm lub rooj los ntsuas. Yog li ntawd, yog tias koj feem ntau zaum ntawm lub rooj ntawm kev saib xyuas, los yog yuav ib lub multimeter yog qhov yooj yim, los yog ncab koj lub caj dab kom pom lub rooj zaum clamp yog qhov tsis xis nyob heev.
3. Nyob rau hauv cov nqe lus ntawm tus nqi, clamp meter nws tsis tsuas yog muaj ib tug multimeter ntawm loj multi-function, tab sis kuj ntau tam sim no transformer, yog li tus nqi kuj kim dua.
