Cov ntsiab lus tseem ceeb ntawm kev siv clamp ammeter
Clamp meter (clamp meter) yog ib qho cuab yeej uas ua ke tam sim no transformer thiab ammeter, thiab yog ib ceg tseem ceeb ntawm digital multimeter. Nws txoj haujlwm ua haujlwm yog tib yam li qhov tam sim no transformer rau ntsuas 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 kev ntsuas tam sim no tuaj yeem dhau los ntawm qhov qhib qhov sib txawv ntawm cov tub ntxhais hlau yam tsis muaj kev txiav, thiab cov tub ntxhais hlau yuav kaw thaum lub ciaj ntswj raug tso tawm. 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, thiab tam sim no yog induced nyob rau hauv lub thib ob kauj los ntawm lub tam sim no. Yog li hais tias lub ammeter txuas nrog lub coil thib ob tuaj yeem qhia qhov tam sim no ntawm qhov ntsuas hluav taws xob.
Lub ntsuas clamp tuaj yeem hloov mus rau ntau qhov sib txawv los ntawm kev hloov qhov hloov. Tab sis nws tsis raug tso cai ua haujlwm nrog hluav taws xob thaum hloov cov iav. Clamp gauges feem ntau muaj qhov tseeb tsawg, 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 qhov ntsuas ntsuas ntsuas qhov sib txawv ntawm cov tam sim no thiab qhov hluav taws xob.
Lub clamp meter yog thawj zaug siv los ntsuas AC tam sim no, tab sis tam sim no nws kuj muaj cov haujlwm ntawm multimeter, uas tuaj yeem ntsuas AC / 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 tam sim no ntawm cov hluav taws xob khiav 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 hauv kev ntsuas qhov siab AC tam sim no.
Clamp tam sim no meter, tseem hu ua clamp meter, feem ntau hu ua nuv meter hauv Taiwan.
Clamp ntawm 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 hauv Circuit Court.
Analog pointer multimeters thiab digital multimeters ntes tam sim no los ntawm kev txiav tawm ntawm lub voj voog, thaum clamp ammeters tsuas yog clamp rau ntawm daim tawv nqaij ntawm lub zog hluav taws xob txhawm rau txheeb xyuas qhov tam sim no. Kev ua haujlwm yog qhov yooj yim thiab tuaj yeem kuaj xyuas qhov siab tam sim no yam tsis muaj kev txuas ncaj qha rau hauv Circuit Court
Clamp ntawm meters, multimeters, thiab rwb thaiv tsev ntsuas ntsuas txhua yam muaj ob hom: analog pointer thiab digital
Kev ntsuas ntau yam: AC thiab DC yog ob qho tib si nyob ib puag ncig 2A txog 200A lossis 400A, thiab tseem muaj cov khoom lag luam uas tuaj yeem ntes cov tam sim no siab ntawm 2000A;
Kuj tseem muaj cov khoom siv hluav taws xob uas tuaj yeem ntes cov tam sim no me me ntawm ob peb mA, nrog rau cov khoom lag luam uas tuaj yeem txheeb xyuas qhov tseeb RMS ntawm cov tsis sinusoidal tsis yog sine tsis xws li cov khoom siv hluav taws xob hloov hluav taws xob thiab cov khoom siv hluav taws xob hloov pauv.
