Txoj kev daws teeb meem ntawm clamp ammeter
1. Thaum ntsuas qhov tam sim no lossis qhov hluav taws xob, tsis muaj qhov qhia txog ib lossis ob peb lub zog, thiab lwm lub zog qhia qhov qub. Yog vim li cas yog hais tias lub zawm hloov ntsia hlau ntawm lub clamp meter yog xoob, los yog kev sib txuas ntawm nws ceg hloov yog twisted thiab tawg. Qhov kev ua tsis tiav no yog qhov tshwm sim ntau tshaj plaws, thiab qhov kev txiav tawm tuaj yeem txuas nrog tom qab qhib lub hau.
2. Kev nyeem cov ntaub ntawv tam sim no tsawg dhau, thiab kev nyeem ntawv ntawm cov ntaub ntawv voltage yog qhov qub.
Feem ntau ntawm cov laj thawj yog vim kev sib cuag tsis zoo ntawm lub puab tsaig thiab sib nqus flux ntau dhau. Lub puab tsaig yuav tsum raug kho kom ua tau zoo. Qhov kev ua txhaum no qee zaum tshwm sim los ntawm qhov luv luv ntawm cov windings, uas yog qhov teeb meem ntau dua rau lub sijhawm no. Feem ntau hais lus, nws yog ib qho tsim nyog yuav tau rov qab raws li cov ntaub ntawv qub, thiab nws yuav tsum muaj hnub nyoog.
3. Cov kev nyeem ntawv tam sim no thiab lub zog hluav taws xob yog nyob rau sab qis, uas feem ntau tshwm sim ntawm lub ntsuas hluav taws xob sab hauv. Qhov laj thawj yog vim li cas cov hlau nplaum yog demagnetized, uas feem ntau yuav tsum tau daws los ntawm magnetization, thiab tseem tuaj yeem hloov kho los ntawm kev txo tus nqi tsis kam nyob rau hauv series nrog lub meter ceg.
4. Yog tias qhov kev nyeem ntawv ntawm ib qho ntawm lub zog tsis raug, qhov kev sib raug zoo yuav tsum tau kho.
5. Qhov taw qhia qhov ntsuas hluav taws xob yog qhov qub, thiab cov iav tam sim no tsis muaj qhov taw qhia. Siv lub multimeter los xyuas qhov kev hloov pauv thawj zaug thiab lub voj voog thib ob kom pom tias muaj qhov txawv txav.
6. Txhua yam tsis muaj lus qhia.
Lub rectifier diodes, meters, keyboards, thiab cov hlua txuas nrog lossis cuam tshuam nrog lub ntsuas ntsuas clamp yuav tsum tau kuaj xyuas kom tawg.
