Cov ntsiab lus tseem ceeb ntawm kev siv clamp ammeters
Clamp meter (clamp meter) yog ib qho cuab yeej uas ua ke tam sim no transformers thiab ammeters, thiab yog ib ceg tseem ceeb ntawm digital multimeter. Nws txoj haujlwm ua haujlwm yog tib yam li ntsuas tam sim no nrog cov transformers tam sim no. Lub clamp meter yog ib qho kev sib txuas ntawm lub tam sim no transformer thiab ammeter. Cov tub ntxhais hlau ntawm qhov tam sim no transformer tuaj yeem qhib thaum lub qhov ciaj ntswj nruj; Cov hlau los ntawm qhov ntsuas tam sim no tuaj yeem dhau los ntawm qhov qhib qhov sib txawv ntawm cov tub ntxhais hlau yam tsis tau txiav nws tawm. Thaum cov ciaj ntswj raug tso tawm, cov tub ntxhais hlau kaw. Cov kab hluav taws xob ntsuas hluav taws xob dhau los ntawm cov tub ntxhais hlau ua lub hauv paus kauj ntawm lub tam sim no transformer, qhov twg tam sim no yog induced nyob rau hauv lub thib ob kauj los ntawm tam sim no. Yog li, lub ammeter txuas nrog lub coil thib ob muaj qhov taw qhia - ntsuas qhov tam sim no ntawm qhov ntsuas hluav taws xob.
Lub clamp meter tuaj yeem hloov mus rau ntau qhov sib txawv los ntawm kev hloov lub zog ntawm qhov hloov. Txawm li cas los xij, nws tsis raug tso cai ua haujlwm nrog lub zog thaum hloov cov iav. Qhov tseeb ntawm clamp zoo li watches feem ntau tsis siab, feem ntau yog li ntawm 2.5 mus rau 5 qib. Rau kev yooj yim ntawm kev siv, kuj tseem muaj kev hloov pauv hloov nrog ntau qhov sib txawv hauv lub 'meter' los ntsuas qhov sib txawv ntawm cov tam sim no thiab voltage.
Lub clamp meter yog siv los ntsuas AC tam sim no, tab sis tam sim no nws kuj muaj cov haujlwm xws li ntsuas AC thiab DC voltage, tam sim no, capacitance, diode, transistor, tsis kam, kub, zaus, thiab lwm yam.
Lub clamp meter yog ib qho cuab yeej siv los ntsuas qhov ntsuas tam sim no ntawm kev ua haujlwm hluav taws xob, uas tuaj yeem ntsuas qhov tam sim no yam tsis muaj kev cuam tshuam. Nws yog ib qho khoom siv hluav taws xob tshwj xeeb tsim los ntsuas qhov siab AC tam sim no.
Clamp ammeters tseem hu ua clamp meters, thiab nyob rau hauv Taiwan, lawv feem ntau hu ua nuv meters.
Lub clamp hom ammeter yog ib qho yooj yim ntsuas ntsuas (tseem hu ua kev ntsuas tsis muaj kev puas tsuaj) uas clamps cov xov hlau thiab kuaj pom tam sim no yam tsis tau txiav tawm ntawm lub voj voog.
Analog pointer multimeters thiab digital multimeters txiav tawm Circuit Court kom pom tam sim no, thaum clamp hom ammeters tsuas yog clamped rau ntawm daim tawv nqaij sab nraud ntawm cov xaim hluav taws xob kom pom qhov tam sim no. Kev ua haujlwm yog qhov yooj yim thiab tuaj yeem kuaj xyuas cov dej ntws loj yam tsis muaj kev sib txuas ncaj qha
Clamp hom meters, multimeters, thiab rwb thaiv tsev ntsuas ntsuas tag nrho tuaj nyob rau hauv ob hom: analog pointer hom thiab hom digital
Standard hom nrhiav tau ntau yam: AC thiab DC ob leeg nyob ib ncig ntawm 2A mus rau 200A los yog 400A, thiab kuj muaj cov khoom uas muaj peev xwm ntes tau siab tam sim no ntawm 2000A;
Kuj tseem muaj cov khoom lag luam to kom pom tias tuaj yeem ntes cov me me tam sim no ntawm ob peb mA, nrog rau cov khoom lag luam uas tuaj yeem ntes qhov tseeb RMS ntawm cov tsis sinusoidal nthwv dej uas tsis yog sinusoidal nthwv dej xws li cov khoom siv hluav taws xob transformer thiab hloov cov khoom siv hluav taws xob.
