Yuav ua li cas lub clamp meter ua haujlwm:
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub clamp ammeter yog ua raws li txoj hauv kev ua haujlwm ntawm qhov tam sim no transformer. Thaum lub clamp ammeter wrench yog nruj, cov tub ntxhais hlau ntawm tam sim no transformer tuaj yeem qhib, thiab cov xaim ntawm qhov ntsuas tam sim no nkag mus rau lub puab tsaig raws li kev sib nrig sib inductance tam sim no. thawj winding ntawm lub cuab yeej. Thaum cov hlau tseem ceeb ntawm lub loosening ciaj ntswj raug kaw, ib qho induced tam sim no yog generated ntawm nws theem nrab winding raws li lub hauv paus ntsiab lus ntawm lub transformer, thiab lub pointer ntawm lub ammeter deflects, yog li qhia tus nqi ntawm cov ntsuas tam sim no.
Nco tseg: Txij li thaum lub hauv paus ntsiab lus yog raws li lub hauv paus ntsiab lus ntawm lub transformer, seb cov hlau core yog kaw nruj nreem thiab seb puas muaj ib tug loj npaum li cas ntawm cov hlau nplaum residual magnetism muaj feem xyuam rau cov kev ntsuas. Thaum ntsuas qhov me me tam sim no, qhov ntsuas qhov yuam kev yuav nce ntxiv. Lub sijhawm no, cov xaim nyob rau hauv kev sim tuaj yeem raug mob ob peb zaug ntawm cov tub ntxhais hlau los hloov qhov piv ntawm tam sim no ntawm transformer kom nce qhov tam sim no.
